Aim: The energy consumption minimization is the important criteria for this research work. The Efficient cluster based routing protocol which minimizes the energy consumption in remote medical applications for WBAN by robust and efficient Improved Energy Harvested-aware Routing clustering body area network (IEH-RCB) protocol using Clustering approach is proposed and compared with Energy Harvested-aware Routing clustering body area network (EH-RCB) protocol. Materials and Methods: In IEH-RCB protocol the energy consumption is achieved using Cost function (CF) selection parameters such as Signal to Noise Ratio (SNR),transmission power, node distance,energy and Innovative node Bandwidth of the node are used. The forwarder node selection enhances the efficiency of the routing protocol in WBAN. In this work there are two groups in which each group has 20 sample sizes (n=20) collected by varying numbers of rounds and it was calculated by calculator.Net with pre-test power of 80% (G-power). To evaluate the effectiveness of the IEH-RCB protocol in terms of Residual energy and Packet Drop Ratio. Results: Simulation results show that IEH-RCB protocol has performed better than EH-RCB Protocol in terms of throughput and energy consumption. The proposed IEH-RCB protocol increased (3.1%) in Residual energy and decreased (2.8%) in packet drop ratio compared with IEH-RCB protocol. The sample T-test also shows that there is a significant difference in IEH-RCB and EH-RCB protocol values in terms of residual energy and packet drop ratio (p<0.05). Conclusion: Depending on the experimental results and independent statistical T-test shows that proposed IEH-RCB protocol has achieved higher performance when compared to EH-RCB protocol.
