Improved Selection of the Best Forwarding Candidate in 3MRP for VANETs

Abstract:

The design of different metrics in hop-by-hop routing protocols for vehicular ad hoc networks (VANETs) has been investigated with the clear objective to improve the performance of VANETs in terms of packet losses and average end-to-end delay. However, the best way of combining these metrics to compute a multiscore value for each candidate node to choose the best forwarding one, is an open issue yet. Based on a previous designed routing protocol called Multimedia Multimetric MapAware Routing Protocol (3MRP), a detailed analysis of the power mean function is done to determine which form of metrics combination will give the best results in terms of packet losses and average end-to-end delay. Extensive simulations have been conducted indicating that the geometric mean has obtained the lowest average percentage of packet losses.
