Link Reliability Based Greedy Perimeter Stateless Routing for Vehicular Ad Hoc Networks

The authors propose an enhancement for the well-known greedy perimeter stateless routing (GPSR) protocol for vehicular ad hoc networks (VANETs), which exploits information about link reliability when one-hop vehicles are chosen for forwarding a data packet. In the proposed modified routing scheme, a tagged vehicle will select its one-hop forwarding vehicle based on reliability of the corresponding communication link. The authors define link reliability as the probability that a direct link among a pair of neighbour vehicles will remain alive for a finite time interval. The authors present a model for computing link reliability and use this model for the design of reliability based GPSR. The proposed protocol ensures that links with reliability factor greater than a given threshold alone are selected, when constructing a route from source to destination. The modified routing scheme shows significant improvement over the conventional GPSR protocol in terms of packet delivery ratio and throughput. The authors provide simulation results to justify the claim.
