Priority Based Packet Balanced Queue MAC Protocol in Wireless Body Area Network.

Wireless Body Area Network is an intelligent health monitoring system. Various models such as IEEE 802.15.4 and IEEE 802.15.6 are used in this network. The key challenges of this network are energy consumption as well as transmission of emergency data in strict real time reliable manner. This protocol presents a novel Priority based Packet Balanced Queue MAC protocol in Wireless Body Area Network which uses IEEE 802.15.6 model. The main goal of this article is to forward the most critical packets over on-demand and non-critical packets. The protocol uses two separate queues for the critical packets based on their threshold value for this purpose. This protocol also consider the remaining time of critical packets for the comparison of same type of packets. Another facility of this protocol is that the on-demand packets can be transmitted earlier if there are no packets in both HTEQ and LTEQ. This work has been more attractive over their counterparts in terms of throughput, packet delivery ration, Delay and Energy Consumption.
