Routing is one of the main issues in designing wireless body area networks. Some drawbacks are revealed in existing routing technologies for practical networks: First, defective criteria e.g., only energy or distance is considered to elect the forwarder nodes. Second, the protocol’s controllable parameters are decided manually, and for all application they stay fix, no automatic tuning is used. Third, the protocol is not altered and based on application specifications they remain optimized. In order to get the better of the above mentioned drawbacks, an EMRP named protocol which is an adaptive Enhanced Multi-hop Routing Protocol is proposed and implemented in this paper. In this, the forwarder nodes are elected based on high energy, low communication distance and low path-loss and low energy consumption loss. The EMRP protocol’s controllable parameters can be adaptively ad-justed and tuned according to application requirement via genetic algorithm. With this view the paper focuses on study and implementation of protocols in NS2 such that it elects forwarder nodes with high energy, low communi-cation distance, low path-loss and low energy consumption. The implementation of (EMRP): Enhanced Multi-hop Routing Protocol and M-Attempt in NS2 and comparison of EMRP and M-Attempt protocols depending on various parameters like Packet-Drop, Energy Consumption, Packet Delivery Ratio (PDR) and Throughput. Network simu-lation results of the proposed protocol exhibit significant improvement compared to existing protocols in terms of lifetime, path-loss, PDR, energy consumption and throughput.
