Ad hoc network is composed of mobile nodes without infrastructure. Depending on a hop-by-hop basis of connection, communications between high-mobility nodes are accomplished via cooperative forwarding. Especially, the vehicular ad hoc network (VANET) is a technology that uses moving cars as nodes to create a mobile network or implement vehicle-to-vehicle (V2V) connection. However, the discussion about live streaming or comparative performance in V2V has been lacked so far. We propose a V2V streaming on omnet platform (VSOP) to build a V2V evaluation of real-time multimedia streaming under TCP/UDP on VANET. We not only compare TCP and UDP, but also analyze and simulate the routing performance in VANET. The major contribution of proposed scheme is a compared study of protocols for real-time wireless application.

The evolution of wireless communication technologies brought great benefits to society, such as multi-connectivity, increased connection speed, low latency, and elevated throughput. However, it has also raised concerns regarding security and the amount of handovers to accomplish this. In this paper, we propose a low-complexity machine learning paradigm for handover prediction in 5G mobile networks by applying the Logistic Regression algorithm. By considering selection criteria like Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), Received Signal Strength Indicator (RSSI), and distance in this algorithm, we show that it is possible to significantly reduce the number of handovers and provide a better quality of service to the user.

TOA-based methods represent an interesting alternative to overcome Important constraints of the existing fingerprinting solutions to locate WIFI devices Indoors, especially in terms of accuracy, stability and quick deployment. However, In some situations the scalabillity, of TOA-based methods to large number of users is expected to be degraded because of the traffic generated by the positioning process. This paper describes the architecture of a novel TOA-based WIN location system and as main contribution presents an assessment of the system's sculability considering different location-based services and scenarios. Achieved results show that system Is viable even In scenarios with a high density of terminals and allows reconsidering some system design Issues In order to Improve the quality or the positioning service.
