Abstract

With the rapid development of wireless technology and the wide availability of low cost wireless devices, the domain of mobile computer networks has expanded in the recent past. Mobile ad-hoc networks promise to be the feature of wireless networking technology, which opens up new frontiers of research and continuous development. One such frontier is VANET – Vehicular ad-hoc network. VANET is a type of mobile ad-hoc network that is formed between and among the nearby vehicles. It enables them to communicate among themselves and with the fixed unit or access point called the roadside unit. The nearby vehicles exchange safety messages among themselves and with the roadside units. The safety messages are broadcasted, which ensures that all the mobile nodes receive the safety message being sent out. This creates several issues such as broadcast storms, collisions and contention among the neighboring nodes or vehicles, which is referred as the broadcast problem. The main objective of this thesis is to propose an efficient scheme, that will greatly reduce or possibly eliminate the broadcast problem in VANETs and to put forth a safety application called as Remote Chase Ender (RCE). This would aid the police officers to end vehicle chases. To address the issue of broadcast problem in VANETs, we propose a broadcast scheme known as i-broadcast and evaluate its performance.
