LeHE-MRP: leveraging health monitoring by enhancing throughput of multi-hop routeing protocol in WBANs.

Health monitoring is one of the interesting and emerging technologies in the field of wireless body area networks (WBANs). In WBANs, routeing plays a major role in developing energy-efficient wireless network. In multi-hop routeing, data transmission consumes less energy as compared to single-hop routeing. In SIMPLE multi-hop routeing protocol, the selection of parent node/forwarder node is selected based on residual energy and distance. To further improve the performance of SIMPLE, we propose a new protocol, named it as LeHE-MRP. In LeHE-MRP, we calculate the cost function, based on residual energy, distance and number of packets to sink node. The node with maximum cost function (parent node/forwarder node) will be selected as data forwarder node to transfer data from other nodes to sink. We compare our LeHE-MRP with two existing state of the art algorithm, M-ATTEMPT and SIMPLE. Simulations show that our scheme improves network lifetime and throughput of a network.
