Handoff Process Improvement in IEEE802.11p Based VANET

Abstract

The IEEE802.11p is a draft standard intended to support wireless access in the vehic- ular environment (WAVE). IEEE802.11p standard o ers the connectivity for the highly mobile vehicular network. The IEEE802.11p standard has introduced the multichan- nel concept but it does not speci ed the algorithm for channel access and the hando process for V2I (Vehicle-to-Infrastructure) communication. This thesis work presents hando process in vehicular communications by adopting IEEE 802.11p based communi- cation systems. This research mainly focuses on reducing the total time taken by hando and support seamless hando process for application demanding the real-time services. The proposed scheme reduces the control messages latency and uses the multi-channel operation of IEEE802.11p that has optimized hando process. The Simulation result shows that the time taken by hando and delay regarding control message is reduced. Simulation results show best performance of the proposed scheme compared to existing scheme.
