Efficiency Broadcast Base Safety Message BSM Through VANET Based on Transmit Packet Coding (TPC)

Abstract

Vehicular networking has emerged with wireless technology concept that supports safety messaging exchange. VANETs provide a collection of interesting safety applications. Many of these applications rely on broadcasting of messages to other vehicles. Basic Safety Messages (BSMs) are an important message type used in safety applications in VANETs. The emergence of Vehicular Ad Hoc Networks (VANETs) is expected to be an important step toward achieving safety and efficiency in intelligent transportation systems (ITS). One important requirement of safety applications is that vehicles are able to communicate with neighboring vehicles, with very low latency and packet loss. The high mobility, unreliable channel quality and high message rates make this a challenging problem for VANETs. In this paper focus on how to enhance the security and scalability of the system for the VANET by improving BSM transfer quality using Transmit Packet Coding (TPC). Briefly discusses issues and challenges for disseminating reliability and low latency of BSM over VANETs. The simulation of different scenario of VANETs and dissemination of transfer BSM content over this network environment using NS2. The result shows suitability of proposed technique over different existing solutions towards effective and efficient techniques in term of delivery ratio and probability for BSM broadcasting over vehicular environments.
