Mobility and Handoff Management in Vehicular Ad-Hoc Networks

VANET is different from MANET due to high mobility of nodes and large scale networks. VANET is a form of network that provide vehicle to vehicle and vehicle to infrastructure communication. The main gaol of VANET is to provide the road safety . Various wireless communication technologies used for VANET, the IEEE 802.11p is to support the medium range communication characteristics of vehicular environments. One of the main issues of VANET is handover process. It can be effectively achieved through FHP mechanisms . The handover algorithm for IEEE 802.11p based on the vehicular communications. This handover based on a V2I communications is done by varying the size of the topology. The performance evaluation and simulation results show that the scheme can minimize the handover latency and packet loss.
