In this study, to observe the relationship between disease and drug, we first constructed disease and drug networks. These networks consist of a disease diagnosis and drugs written by doctors. After the disease and drug networks were generated, a link prediction was done concerning similarity values between nodes. Experimental results show that the proposed method finds satisfactory results. By examining these constructions and connections it is feasible to achieve affinities, similitudes, and patterns and it is likewise conceivable to make it feasible to achieve.

Non-orthogonal multiple access (NOMA) scheme provides multi-user scaling (multiplexing), optimum spectral efficiency (SE), excellent user-pairing improvement, and a single resource block sharing by multiple users because of which it is a more preferable scheme over orthogonal multiple access (OMA) for the next generation technologies. This article investigates comparative analysis of various power allocation algorithms in multiple-input multiple-output-NOMA (MIMO-NOMA) technology and to come up with the best power allocation algorithm which suited best for MIMO-NOMA technology. Firstly, comparison analysis will be carried out considering direct methodologies followed by power allocation algorithm using Deep Neural Network (DNN) along with the Depth limited search (DLS) algorithm. These techniques are tested on two users initially then followed by multi-user communication. Allocating optimal power to the poor signal strength user terminal (user not receiving appropriate signal power) is a difficult task in actual scenario, and moreover, SIC also creates complexity in the proper allocation of Base station (BS) source power. The above problems can be solved with the assistance of the DNN along with the DLS algorithm, where the weaker user receives maximum power and the stronger user receives minimum power. The DNN-MIMO-NOMA technology, which is based on the DLS algorithm, helps user terminals to get their signals free from noise (inter_user_interference) and with greater precision. The DLS process (algorithm) offers higher potential in MIMO-NOMA with DNN technology for successfully applying SIC. Here, MIMO helps to improve the channel gain. A DLS provides an optimum power allocation (OPA) based on the position of user equipment. The simulation results show that the power allocation method using DNN along with DLS algorithm achieves better performance than the traditional multi-user.

However, NOMA's primary issue is the error with successive interference cancellation (SIC). This paper aims to examine bit error rate (BER) downlink (DL) NOMA power domain (PD) for various SNR levels in additive white Gaussian noise (AWGN) as well as in Rayleigh fading channels utilizing Quadrature Phase Shift Keying (QPSK) for three different scenarios, to clearly differentiate the more effect of distance, bandwidth (BW), and power location coefficients factors using the MATLAB simulation software program. The BER versus SNR results were obtained in terms of charts for different BWs, distances, and power location coefficients. According to the findings, the BW parameter has the strongest effect on BER DL NOMA PD when compared to the distance, and power location coefficient parameters.

This key component of Intelligent Transportation Systems (ITS), is impacted by the vehicle’s mobility and suffers from frequent link disruptions caused voluntarily or intentionally by malicious attackers, which make the security issue more challenging and even life-threatening when critical attacks occurred. This work focuses on analyzing the smart grayhole attacks within VANets environments and evaluating the Reputation-based Ant Colony Optimization Dynamic Source Routing (RACODSR) and Dynamic Source Routing (DSR) protocols performances under two different scenarios. For this purpose, VANets mobility models with and without collisions are generated using OpenStreetMap and Simulation of Urban Mobility (SUMO) tools and simulated in Network Simulator NS2 to assess the effectiveness of the compared protocols using the Drop rate, Packet Delivery Ratio, Throughput, Jitter, End-to-End delay, and consumed energy metrics.

D2D resource optimization scheme has been thoroughly investigated in the literature to manage interference and enable its smooth integration into the future cellular network in recent years as an increasing number of papers are published each year. We believe systematic categorization of literature in the area will help readers to comprehend the strengths, weaknesses, and trends of the solution approach. However, a survey that discusses all aspects, requirements, and challenges of D2D resource optimization is largely missing. Hence, in this paper, we aim to develop a comprehensive survey that fills the gaps found in the previous literature. Based on the surveyed papers, it will figure out ideas that have been thoroughly explored and those that assume the potential for further research.

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

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.

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.

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.

We focus

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

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.

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.

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.
