Analyzing and reviewing cumulative cost functions of simple protocol in wireless body area network

Wireless Body area network (WBAN) has become an area of special interest for the researchers due to its vast applications in the medical field. The major components of WBAN are sensors and gateway where sensors are responsible for collecting and transmitting physical and biological status of human body. The gateway is responsible for linking sensors with any external server for valuable output. As it has been always challenging to enhance network performance, energy efficiency, higher throughput and longer stability time in WBAN. To overcome such issues many routing protocols initiated, SIMPLE protocol is one of them. Till now there are 6 cost functions modified from the SIMPLE Protocol, It is also challenging to tell which one has the better ability to work well under certain condition. In this paper, we have compared and analyzed all the cumulative CF’s of SIMPLE protocol for the following parameters, a) throughput, b) packet sent to the sink, c) packet drop, d) packet received at the sink, e) residual energy, f) path loss and e) delay. The simulations are performed for the rounds ranges from 0-8000 in MATLAB simulator. The efficient cost function is also categorized on the basis of electing the parent node to measure the performance.
