Improving Proactive Routing in VANETs with the MOPR Movement Prediction Framework

摘要: Wireless vehicular communications are attracting more and interests for applied research in industries. Most of the efforts spent deploying Vehicular Mobile Ad-Hoc Networks (VANETs) applications such as active safety Internet services. This paper addresses routing problem VANETs related to comfort infotainment users where an unicast protocol optimized fast topology changes is needed. In previous work, we have proposed a new movement prediction-based concept called MOPR which already reactive AODV order improve its performances by exploiting vehicules movements patterns. this first propose design concept, then apply it OLSR optimizing procedure selecting MPR (Multipoint Relay) sets well that determining optimal path from each pair vehicles. Basically, connected graph composed most stable wireless links VANETs. We conduct several simulation scenarios investigate performance modified (OLSR-MOPR) studying metrics including end-to-end average delay, overhead, packet delivery ratio, overhead ratio. The results various show great improvements comparing basic OLSR.
