Precedence based MAC protocol with cogent contention scheme for WBAN

Abstract

A zero hour treatment in Wireless Body Area Network WBAN in healthcare consortium could be a demanding task as it associates transmission of time sensitive vital datum to the receiver for a prompt medical analysis of the patient The ecumenical research endeavor in biosensors involve miniaturization of the health monitoring gadgets and power sources that contribute to a short hospital stay of the patients with uninterrupted self or remote monitoring If there is large time delay during information transfer it might be a life threatening situation to the patient Therefore the cogitated research pursuit intents to provide successful transmission of data according to the priority type to the respective end user with reduced delay and energy consumption within the permissible limit set by the medical arena A potent scheme that supports heterogeneous traffic loads for quick ingress in the medium to cut down the overall delay of the WBAN with a balance on the energy expenditure of the biosensor node was proposed by incorporating appropriate modifications in the superframe A routing protocol assimilated with an effective contention admittance technique and Cogent Data Frame Cumulation CDFC mechanism in IEEE 802 15 4 at the newlineMedia Access Control MAC layer was formulated and implemented to reduce energy consumption of a node thereby enhancing its medium utilization that upsurges the throughput and lifetime of the entire network Reducing the power expenditure and latency of the sensor node with the proposed protocol was achieved by formulating the selection of packet and allocating the channels according to their priority type newline newline
