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.

The disruptions induced by the mandatory social distancing norms amidst the COVID-19 pandemic has brought it to the centre stage as it facilitates seamless delivery of education to mobile-users on the go. The ever increasing penetration of low-cost smartphones and remarkable advancement in wireless communication technologies has made M-learning ubiquitous and affordable. This paper highlights the roles that mass-adoption of mobile phone devices have played in sustaining K-12 schools. We review the impact that latest developments in communication technology and the deployment of LTE-WiFi coexistence, 5G, and Wi-Fi6 networks will have on M-learning applications. Further, we highlight the challenges that need to be addressed so that the higher penetration of mobile phones and deployment of wireless network technologies can be optimally harnessed for an improved M-learning experience.

(MANET). It powerfully self-composes in subjective and impermanent system topologies. These moveable ad-hoc
systems are dishonest and powerless to any interruption in light of their remote association approach. Subsequently, the
data from these systems can be stolen effectively just by presenting the aggressor nodes in the system. The hop count
metric is calculated to determine the straight route degree. For this reason, directing conventions are arranged. Among all
the potential assaults on MANET, identification of wormhole attack is considered to be most problematic. One malevolent
node gets packets from a specific area, tunnels them to an alternate transmissible node arranged in another area of the
system and deforms the full steering strategy. All routes are merged to the wormhole set up by the aggressors. The total
directing framework in MANET gets diverted. Here in this paper, a procedure for identifying malevolent nodes in movable
ad-hoc system has been proposed (E-CREDND) and this scheme is critical for the regions where the route separate in the
midst of source and goal is two nodes only. This scheme isn't appropriate for those situations where multi-hops are
exhibited in the midst of transmitter and recipient. In the anticipated investigation, another procedure is executed for the
identification and separation of aggressor sensor nodes from the system. The anticipated plan is used in NS2 and it is
portrayed by the propagation results that the anticipated plan demonstrates better execution in correlation with existing
methodologies.

ambulatory palliative care to monitor the patients’ health status – especially during the transition phase from
hospital to home since this phase is critical and often patients are re-hospitalised. Following an user-centred
design approach, we performed interviews with patients recruited at the Clinic of Radiation Oncology of the
University Hospital Zurich, Switzerland. The patient group was perceived as vulnerable and varied largely
in physiological burden and mental aspects. Special needs concern primarily obtrusiveness of the system
and sensitivity in the work with this patient group. With the deployment of the system, we gathered first
experiences: the first patient was tracked over 12 weeks resulting in 84 tracked days, 181 digital questionnaire
answers, 40908 collected GPS points, 861 hours of heart rate measurements and positive feedback of the

challenging issue. The lack of information at the TCP layer about the link quality will result in inaccurate
transmission rate. Therefore, TCP needs to have sufficient information about the environment and the
different characteristics of the lower layers to improve the performance. To achieve this goal we proposed a
cross-layer scheme which makes use of the information stored in the 802.11n compressed block acknowledged
bitmap about the status of the transmitted subframes of the aggregated frame. This information is fed to the
TCP transmission mechanism as a new criterion to adjust the TCP transmission rate with accordance to the
aggregation level and channel quality. The simulation results show that the proposed scheme improves the
TCP performance in term of throughput and packet loss.

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.

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

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.

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.

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.

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.

These networks are characterized by high mobility receivers which perform frequent handoffs across homogenous and heterogeneous access networks while maintaining seamless connectivity to the multimedia services. In order to ensure secure delivery of multimedia services to legitimate group members, the conventional cluster based group key management (GKM) schemes for securing group communication over wireless mobile multicast networks have been proposed. However, they lack efficiency in rekeying the group key in the presence of high mobility users which concurrently subscribe to multiple multicast services that co-exist in the same network. This paper proposes an efficient multi-service group key management scheme (SMGKM) suitable for high mobility users which perform frequent handoffs while participating seamlessly in multiple multicast services. The users are expected to drop subscriptions after multiple cluster visits hence inducing huge key management overhead due to rekeying the previously visited cluster keys. The already proposed multi-service SMGKM system with completely decentralised authentication and key management functions is adopted to meet the demands for high mobility environment with the same level of security. Through comparisons with existing GKM schemes and simulations, SMGKM shows resource economy in terms of reduced communication and less storage overheads in a high speed environment with multiple visits.
