Improved selection of the best forwarding candidate in 3MRP for VANETs

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.This work was supported by the Spanish Government under project “sMArt Grid using Open Source Intelligence.
