The application of mobile technologies in communication systems could be tracked back into 1980s. The emerging of cognitive radio targeted on the revolutionary spectrum access paradigm has sparked a radical change on wireless mobile system design, development, and performance analysis. Since then, the state-of-the art of wireless communications has been significantly advanced, from substantial improvement on spectrum usage, smart adaptation and coexistence in radio and network environments, fundamental enhancement on performance and capacity, to considerable reduction of complexity in mobile network management. This trend will strengthen even more with the advent of fifth generation (5G) communication networks that will impose new challenges, related mainly to the heterogeneity of such networks, the improvement of the quality of experience of users, and the efficient and sustainable use of network resources. Solutions for energy efficient, sustainable future Internet are heavily relied on advanced technologies, new ways of thinking on network design and development, as well as new theoretic foundations. Mobile communication ecosystems need to be equipped with advanced intelligence coming from machine learning, data analytics, and cognitive computing to meet the challenges. We believe mobile communications will remain an important and active area of research for the next several decades. It becomes necessary to provide a common forum to publish high quality papers, and to offer readers a single source to get inspiring ideas and important findings in this area.

However, the Network Coding-enabled WSNs are affected by
various attacks, such as pollution attacks. Many HMAC schemes have been proposed in the literature to secure packets against pollution attacks. In 2015, Esfahani et al. proposed a dual-homomorphic MAC scheme based to the construction of two different MACs to ensure the integrity of coded packets. Their solution has many weaknesses in terms of security against tag
pollution attacks. In this paper, we improve their scheme by proposing a novel HMAC scheme for NC enabled WSNs, called E-HMAC, based on multi-linear space to check the integrity of coded packets. The simulation results demonstrate the ability of our proposed scheme to secure the coded packets with a low key storage overhead and communication overhead, compared to Esfahani et al.’s scheme.

Specification and implementation of such applications should be modular, extendable and reusable. Performance, re-usability of once established capabilities and easy integration of devices are main objectives. It relies on extendable common data formats. Edge computing capabilities allow to analyze and transform this data. These computing modules can also manage an arbitrary number of devices with similar capabilities interchangeably. The framework is ready to be used. Nodes for CSharp, Javascript, C++ and Java exist and features are continuously expanded. Ubi-Interact lets users build real-time systems with modular components that can separate system behaviour from base API calls, leaving the user free to explore and maintain a combination of software and hardware each running in their native environment.

One of the salient functions of cognitive radio is spectrum sensing which is used to avoid the interference of the unlicensed secondary users with licensed primary users and spot the available spectrum for enhancing the spectrum usage. The frequency band that a secondary user can utilize without interfering with any licensed primary users are called spectrum holes. Cooperative sensing is a remedy to improve the sensing performance, in which secondary users (SUs) cooperate among themselves to sense the spectrum and find the spectrum holes. Here we propose a deep reinforcement learning based spectrum sensing to discover the spectrum holes. We implement a deep reinforcement learning based method called Deep Q-Network (DQN) to find the spectrum holes. The secondary users (SU) uses the DQN to find the vacant channels in the spectrum effectively. The secondary user (SU) senses the spectrum associated with a single primary user (PU). The spectrum is sensed and the spectrum holes are detected to satisfy the requirement of the secondary user (SU).

These requirements include higher uplink and downlink throughput requirement, low latency, and consistent throughput even at the cell edge. Present day 4G/5G Network faces a lack of resource availability for highly sophisticated applications like interactive multimedia. While 4G/5G networks do have a QoS mechanism to handle multiple varieties of traffic requirements, they are passive. At best, initial negotiated QoS are changed on a reactive basis.

OBJECTIVES: This work proposes a dynamic QoS management scheme so that the overall necessary resource allocation for interactive multimedia and non-interactive applications can occur.

METHODS: The scheme uses mobile agents which can efficiently predict possible disruption in QoS and helpboth server and users to adapt to changing network situation. This way user can be notified of an expected or estimated service quality change in advance, timely adaptation is possible. use this information to for efficient QoS negotiation and re-negotiation.

RESULTS: The developed scheme has been tested with different sizes of the 4G/5G networks with several virtual reality users along with other background loads of applications.

CONCLUSION: Results are quite encouraging and the system is practically implementable.

V2V communications evolve the exchange of Wave Short Messages (WSM) between vehicles for safety advertisement, either in one hop or multi-hop broadcasts. However, previous DSRC evaluations have shown that this protocol is highly sensitive to transmission conditions, making it difficult to predict its performance. We are interested in finding the best configuration parameters for safety messages broadcasting over DSRC in typical African urban environments. Extensive simulations through the widely used network simulator OMNeT++, Veins, and SUMO show that only a very small fraction (around 30%) of the WSM reach the neighboring vehicles on time. Furthermore, the rebroadcasting of WSM further deteriorates the performances. Thus, the protocol as it is needs to be improved for its application in our environment.

The efficacy of the greedy methods differs and varies; nevertheless, the algorithms are similar and process the same data at a forwarding node. Their commonalities potentially allow the online assignment of different methods for more efficient progress forwarding in heterogeneous MANET environments. We define a multimethod multi-greedypacket forwarding approach in this paper. Using the IPFIX packet flow measures, we demonstrate the multi-greedy scheme for the performance of repetitive packet routing tasks that permit exploration-exploitation application. The flows report reveal the optimal efficiency of each base greedy method in each flow which aggregates to the multi-greedy design. In comparison to the base methods, the case multi-greedy methods show considerable performance improvement in PDR, hop-count, and delay measures.

To accomplish such goals, new antennas compatible with 5G technology are necessary. Patch antennas, being made of resistant and cheap materials, easy to mass-produce and low profile, represent a solid candidate for deployment in a 5G scenario. This paper aims to serve as a comprehensive guide for designing an antenna using microstrip technology, oriented to provide 5G services. This paper proposes a top-down approach, explaining first the general concepts and orienting the study towards more specific subjects. The topics discussed are the underlying technologies of 5G, patch antennas, circular polarization and array theory. Each topic provides an explanation of its fundamental principles, with an approach intended to be comprehensive instead of technical, and focusing towards giving practical design considerations for a 5G-oriented antenna.

LTE network technologies provide a high speed triple play services like data, voice, and video with QoS provision. The resource allocation techniques primary concerns are the QoS support that aims to satisfy the diverse service requirements as well as to guarantee the required data rates from the available resources. In this context different network architecture for broadband wireless data network like LTE made OFDMA a practical access technology for wireless multimedia services. Therefore, this survey investigates the techniques that aim to support QoS for real-time and non real-time services in OFDMA-based packet scheduling and adaptive multiuser frequency-time domain resource allocation. Moreover, this survey addressed the different aspects of resource allocation algorithms design to be contributed to the emerging 5G next generation networks.

As an Internet systems simulator, ns-3 simulator provides an ideal simulation environment for network research. However, ns-3 is lack of table-driven IPv4 routing modules. Despite the fact that a routing protocol is a mandatory component of a network, it is necessary to introduce a table-driven routing protocol for the ns-3 which is able to maintain the network connectivity and consistency. To this end, we introduce a distance vector IPv4 wired routing protocol for the ns-3 simulator (DVRP). The proposing protocol is developed as a table-driven wired routing protocol. In this study, we describe the proposing routing protocol, including its design, implementation, behavior on networks, and limitations.

These systems are being deployed in tasks that are time-consuming, expensive or inconclusive if accomplished by human intervention. Design, development and testing of such vehicles using actual hardware could
be quite costly and dangerous. Another issue is the limited outdoor usage permitted by Federal Aviation Administration regulations, which makes outdoor testing difficult. An optimal solution to this problem is to have a simulation environment where different operational scenarios, newly developed models, etc., can
be studied. In this paper, we propose GNSSim, a Global Navigation Satellite System (GNSS) simulation framework. We demonstrate its effectiveness by integrating it with UAVSim. This allows users to experiment easily by adjusting different satellite as well as UAV parameters. Related tests and evidence of the correctness
of the implementation are presented.

mechanism enables transport of IPv6 datagrams with the required minimum MTU of 1280 bytes over
802.15.4-based networks. With the goal of a fully standardized WSN protocol stack currently necessitating a route-over approach, i.e., routing at the IP-layer, there are two main choices for any 6LoWPAN implementation with regard to datagram fragmentation: Hop-by-hop assembly or a cross-layered direct mode, which forwards individual 6LoWPAN fragments before the whole datagram has arrived. In addition to these two straightforward approaches, we propose enhancements based on adaptive rate-restriction for the direct forwarding and a retry control for both modes to reduce the number of losses of larger datagrams. An evaluation of these modes in a simulation environment and a hardware testbed indicate that the proposed enhancements can considerably improve PRR and latency within 6LoWPAN networks.

We focus
on the LTE module of ns-3, which is also known as LENA. Our contribution is twofold. On one hand, we propose a set of new features for the LTE module, including a new model for simulating obstacles blocking the propagation of radio signals, and a handover model suitable for the offline
evaluation of mobility management solutions. On the other hand, we describe in detail the setup of the simulation scenario, highlighting the challenges that we faced during the implementation and discussing the chosen configuration parameters. Finally, we present some simulation results that
we obtained with the proposed approach.

This intelligently avoids interference amongst users and provides the ability to use up all available bandwidth on the RF spectrum. There are many ways in which the communication can be demonstrated. This paper examines how we have implemented a cognitive radio network testbed using software defined radios (SDRs) for multimedia communications, where components that have been traditionally implemented in hardware are instead implemented by means of software on a personal computer or embedded system to communicate and transfer a file between each other. We attempt to demonstrate potential use of SDRs for future multimedia applications.

devices and/or monitoring from a distant part. It is very easier and cost effective to implement a wireless system.
Because there are barriers in implementing wired system. That is why wireless system is much effective than wired.
But the wireless system has also some problems or deficits. One of them is signal loss during the transmission due to
various causes like surrounding environmental reason and others. If transmitted signal is lost the receiver will remain
completely blind as it is not receiving the signal. Another one can be the receiver is unable to receive signal due to the
technical fault of receiver end whether the transmitted signal is stable. That is why an acknowledgement system is
necessary to determine whether the receiver is receiving the transmitted signal or not. The developed system is an
effective and low cost system with nRF24L01P transceiver module and Arduino Uno to determine that the receiver is
working accordingly or not or is there any technical fault.

The initial view of practitioners and researchers was that radio-equipped vehicles could keep the drivers informed about potential safety risks and increase their awareness of road conditions. The view then expanded to include access to the Internet and associated services. This position paper proposes and promotes a novel and more comprehensive vision namely, that advances in vehicular networks, embedded devices and cloud computing will enable the formation of autonomous clouds of vehicular computing, communication, sensing, power and physical resources. Hence, we coin the term, autonomous vehicular clouds (AVCs). A key feature distinguishing AVCs from conventional cloud computing is that mobile AVC resources can be pooled dynamically to serve authorized users and to enable autonomy in real-time service sharing and management on terrestrial, aerial, or aquatic pathways or theaters of operations. In addition to general-purpose AVCs, we also envision the emergence of specialized AVCs such as mobile analytics laboratories. Furthermore, we envision that the integration of AVCs with ubiquitous smart infrastructures including intelligent transportation systems, smart cities and smart electric power grids will have an enormous societal impact enabling ubiquitous utility cyber-physical services at the right place, right time and with right-sized resources.

Telemedicine includes several applications such as remote monitoring of chronically ill patients, monitoring people in their everyday lives to provide early detection and intervention for various types of diseases, computer-assisted physical rehabilitation in ambulatory settings, and assisted living for the elderly at home, as well as remote monitoring of injured people in a post-disaster situation. These new applications require a reliable, wireless communication link between the devices implanted in the patient’s skin and a clinician. In this article, this issue is discussed and a list of performance criteria for the different communication links used are addressed, especially focusing on the satellite link. Then an adaptive air interface which is designed to meet the performance constraints of bidirectional satellite communication links in an emergency situation in Ku/Ka/Q/V bands where when strong channel impairments occur is described and analysed.

Indeed through its contactless interactions with external entities, the smartphone of an individual will become an essential authentication tool for service providers such as transport operators. However, from the point of view of the user, carrying a part of the service through his smartphone could be a threat for his privacy. Indeed, an external attacker or the service provider himself could be tempted to track the actions of the user. In this paper, we propose a privacy-preserving contactless mobile service, in which a user’s identity cannot be linked to his actions when using the transport system. The security of our proposition relies on the combination of a secure element in
the smartphone and on a privacy-enhancing cryptographic protocol based on a variant of group signatures. In addition, although a user should remain anonymous and his actions unlinkable in his daily journeys, we designed a technique for lifting his anonymity in extreme circumstances. In order to guarantee the usability of our solution, we implemented a prototype demonstrating that our solution meets the major functional requirements for real transport systems: namely that the mobile pass can be validated at a gate in less than 300 ms, and this even if the battery of the smartphone is exhausted.

However, with a large base station (BS) antenna, the non-square channel matrix restricts the zero-forcing (ZF) precoder rotations to obtain the best optimal solution with the per-antenna power allocation. In this paper, we propose the beamforming and lattice reduction (LR) approach to restrain the channel matrix and transform the lattice of the channel vectors to be near orthogonal. Numerical results show that the LR-based ZF precoder outperforms other ZF precoder schemes, such as, the norm approximation of the beamforming matrix. In particular, the sum rate of the proposed optimal ZF precoder requires a small number of BS antenna. Subsequently, with the strong line of sight (LoS) channel, the optimal power allocations in the subchannels depend on the dominance of the users in order to achieve substantial multiplexing and diversity gains. Speciﬁcally, the Ricean channel gain with the water-ﬁlling allocation at high SNR is non-negligible.
