Multi-criteria Receiver Self-Election Scheme for Optimal Packet Forwarding in Vehicular Ad hoc Networks

Free registration required

Executive Summary

In most of the existing geographical forwarding methods of Vehicular Ad hoc NETwork (VANET), a node periodically sends "Hello" messages to determine the positional information of its direct neighbors. Each node stores and maintains more or less accurate information of its direct neighbors in a table. However, due to high mobility vehicles and traffic congestion the stored neighbors information is quickly outdated, failure notification increases significantly, and leading sub-optimal path. Furthermore, the transmission of periodic "Hello" messages and table maintenance consume resources, which is not suitable for sensitive VANET.
