Throughput analysis of next-hop forwarding method for non-linear vehicular Ad Hoc networks

Abstract

Position based routing plays a significant role in multi-hop Vehicular Ad hoc Networks (VANETs), due to high mobility of nodes. Selection of nexthop node is crucial to improve the performance of routing. In this paper, we have proposed a method for selecting next-hop forwarding node based on the distance between the source and next-hop node and link quality. Next-hop node is selected based on Expected Progress Distance (EPD) criteria. The EPD is estimated in terms of expected distance between the source and next-hop node. The expected delay (ED) and throughput (Th) are also estimated for the proposed method. The mathematical model derived for calculating EPD, delay, and throughput are simulated in MATLAB and evaluated the performance of the proposed method. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2012.
