Priority based AODV routing protocol for critical data in Wireless Body Area Network

Wireless Body Area Networks (WBANs) is one of the most promising approaches for improving the quality of life, by allowing remote patient monitoring and other ubiquitous health monitoring applications. In this type of networks, traffic routing plays an important role, which collects the information from bio sensors and sends it towards the sink. Some data are very critical under certain situations and should be ensured with high end-to-end reliable transmission and lower delivery delay. This paper introduces a new Priority Queuing Algorithm for AODV routing protocol, which differentiates various types of traffic based on the critical data. The proposed protocol has been simulated using different scenarios and obtained results are analyzed using NS2 simulator.
