A Location Based Delay and Packet Loss Optimized Communication Mechanism involving Handoffs in Vehicular Ad Hoc Network

Abstract

Vehicular ad-hoc network faces many challenges, in particular frequent handoffs due to high mobility of vehicles is a serious performance limitation factor and is probably the most critical process in terms of packet loss and delay. In this paper an efficient mechanism of Vehicular Ad-hoc Networks (VANETs) is proposed for making handoff decision that considers both Received Signal Strength (RSS) and Global Positioning System (GPS) information along with maps. Furthermore; the proposed mechanism focuses on nodes moving at high speeds while receiving and saving the relevant information in buffers. This particular approach not only minimizes delay and packet loss but is also used to retransmit the lost packets locally. The addition of this capability in the proposed mechanism contributes in improving the packet loss in less crowded areas having limited available connectivity.
