Entropy-Based QoS Route Stability Technique for Vehicular Ad Hoc Network

Abstract

Vehicular ad hoc network (VANET) has received significant considerations with the prominent introduction of real-time application that triggers research activities on area of Quality of Service (QoS). QoS provisioning for guaranteeing a data route to be available and stable for a longer period remains the most challenging tasks VANET. Therefore QoS of routing is highly affected by mobility features of vehicles in VANET environment. We propose simple QoS routing strategies capable of providing optimal paths with certain QoS requirements route stability based on received entropy. Extensions were added to the messages used during route discovery/reply with route stability information for optimal and stable route. Results obtained indicate improvements in terms of average network throughput, average network delay and percentage of packet drop.
