Effect of Body Node Coordinator (BNC) positions on the performance of intra-body sensor network (Intra-WBSN)

In this paper our work investigates the performance of Intra-WBSN by placing the Body Node Coordinators (BNCs) at different positions in Intra-WBSN. Physiological data is collected by bio-sensor nodes and forwarded to BNC through intermediate node or forwarder. The forwarder node is selected on the basis of cost-function. Cost-function depends on the residual energy of node and path-loss between sensor node and BNC. In the execution of each round, body sensor node having maximum value of cost function is selected as a forwarder. The performance parameters for the investigation are the network stability period, network life-time, residual energy throughput and path-loss.
