A Novel Approach for Energy Efficiency and Congestion Control in WBAN

Wireless Body Area Network (WBAN) is a subfield of Wireless Sensor Networks (WSNs). WBANs are used to remotely monitor the well-being of patient’s body. The WBAN has been experiencing different problems. Congestion control and energy proficiency are one of the issues. Diverse makers have been created vivacity effective routing strategy and congestion control strategies separately. This examination has been sorted out to build up an energy efficient routing and congestion control system. This paper proposes a novel routing approach for body area networks. The major objective of the work is to void the congestion in the network and to enhance the performance of the network in the terms of network lifetime and network energy consumption. For this purpose, a cost function is introduced that is evaluated on the basis of the distance, residual energy and delay of the respective nodes. Then the work also enhanced the routing criteria by introducing the firefly optimization technique for the selection of forwarder node for route creation. Along with this the proposed work also evaluates the rate of congestion in the network so that the routing can be performed effectively. The simulation of the work is done by using the MATLAB. The results represent that the network energy consumption, path loss, data delivered to the sink is quite effective and results to the enhancement in the network lifetime.
