A New Load Balancing Routing Scheme for Wireless Body Area Networks

In the wireless body area network (WBAN), being constrained by the sensor size, the battery, computing and store resources of each node is very limited. In the multi-hop environment, it is necessary to save energy and balance the energy consumption in the network. At present, most of the research work selects the route with high residual energy, but does not consider the heterogeneity of the WBAN nodes. Since the energy distribution and energy consumption rate of each node in the WBAN may be different, the selection of the forwarding node needs to consider more factors. In this paper, we propose a novel routing scheme LBEE, which evaluates the cost value according to the current traffic load and residual battery of the node, selects the high-energy, low-load routes for data forwarding, and balances the network load too. The simulation show that this scheme can improve the network's overall lifetime, throughput and loadsharing.
