Routing Optimization in Vehicular Networks : A New Approach Based on Multiobjective Metrics and Minimum Spanning Tree

الملخص EN

Recently, distributed mobile wireless computing is becoming a very important communications paradigm, due to its flexibility to adapt to different mobile applications.

As many other distributed networks, routing operations assume a crucial importance in system optimization, especially when considering dense urban areas, where interference effects cannot be neglected.

In this paper a new routing protocol for VANETs and a new scheme of multichannel management are proposed.

In particular, an interference-aware routing scheme, for multiradio vehicular networks, wherein each node is equipped with a multichannel radio interface is investigated.

NS-2 has been used to validate the proposed Multiobjective routing protocol (MO-RP) protocol in terms of packet delivery ratio, throughput, end-to-end delay, and overhead.
