Performance analysis on mobility of ad-hoc network for inter-vehicle communication

This paper presents the feasibility of using an ad-hoc network as an infrastructure for a small group of inter-vehicle communication network. Mobile ad-hoc networking with wireless LAN infrastructure can be employed to build inter-vehicle communication based network. The irregular driving environment pose a challenge to the performance of a wireless LAN. We have measured transmission characteristics for sending and receiving high data volumes using TCP and UDP in vehicles moving on IEEE 802.11b. Our framework aims to evaluate the effect of our proposed mobility models on the performance of dynamic source routing (DSR) based on measured data. Proposed mobility models are varied by conducting the experiments under different driving environment, driving conditions, and vehicular patterns. Our result shows that the routing protocol mechanism, such as route discovery and route maintenance, does not interrupt the data transmission seriously.
