Performance analysis of real-time streaming under TCP and UDP in VANET via OMNET

Abstract

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.
