Aim: The aim of the study is to minimize the energy consumption in wireless body area networks by using Improved Energy-efficient Routing and QoSsupported Traffic Management (IERQTM) protocol compared with Energy-efficient Routing and QoSsupported Traffic Management (ERQTM) protocol. Materials and Methods: In this research clustering approach based routing algorithm in IERQTM is proposed to minimize the energy consumption in ERQTM by efficient selection of cluster head using various parameters such as nodes’ residual energy, energy consumption rates, distance to controller, and Innovative path-loss effect along with Genetic algorithm (GA). In this work there are two groups in which each group has 20 sample sizes collected by varying number of rounds and throughput it is calculated by calculator. Net with pre-test power of 80%(G-power). To evaluate the efficient energy optimized routing IERQTM protocol in terms of Residual energy, throughput. Results: Simulation results show that IERQTM protocol has performed better than ERQTM protocol in terms of residual energy and throughput. The IERQTM protocol achieved (3.6%) higher residual energy and (4.9%) higher throughput compared with ERQTM. The sample t-test shows that there is a less significant difference in IERQTM and ERQTM values in terms of residual energy, and throughput (p<0.05). Conclusion: Depending on the experimental results and independent statistical T-test shows that proposed IERQTM protocol has achieved higher performance when compared to ERQTM protocol.
