A Novel Balanced Routing Protocol for Lifetime Improvement in WSNs

In this paper, a novel balanced routing protocol with two uncorrelated paths is proposed for improving the imbalanced load around a sink connection area (SCA) and reducing the energy consumption in wireless sensor networks (WSNs). To achieve this, two uncorrelated shortest paths are determined for each node to the sink with the optimal path transmission cycle to avoid unnecessary load congestion in the SCA and all the other intra-layers. The proposed scheme can achieve the even power consumption for each intra-layer in a larger scale network and double the network lifetime, as compared to the traditional shortest path routing.
