A reactive routing protocol for VANETs based on composite metric concept

In the last years, the interest on vehicular networking has incredibly increased in the scientific and industrial community, due to the enormous potentialities that this emerging technology offers. In this context, routing protocols become fundamental for enhancing QoS, related to the different services offered to final users. The implementation of new routing protocols becomes challenging in VANETs so, at this aim, we propose a new reactive routing scheme in which the available channels are exploited for the optimization of a new metric, which takes into account different characteristics. Network Simulator 2 (NS2) has been employed to validate the Reactive Routing Protocol for VANETs (RRPV), showing how it performs better than other protocols in terms of different performance variables.
