Abstract: Wireless body area network is a new emerging field in WSN. WBAN is a wireless network of wearable computing devices. The most important application of WBAN is health monitoring. In WBANs the wireless sensors are deployed in the human body and these sensors are used to monitor the various human body parameters such as blood pressure, glucose level, heart rate etc. WBANs capture accurate and quantitative data from a variety of sensors. In this work we propose a energy efficient routing protocol for WSN/WBANs that uses a combination of multi-hop and single-hop topology. We use the concept of cost function in order to select the forwarder node. The calculation of cost function takes into consideration the residual energy parameter into account thus making sure that the energy consumption of the network is balanced. MATLAB simulations of proposed routing algorithm have been performed to obtain the simulation results. The simulation results show that our proposed protocol increases the network stability and the nodes stay alive for a longer duration, which in turn contributes to higher packet delivery to the sink
