Load Balance Routing Algorithm Based on Cross-Layer Power Control for Wireless Sensor Network
The traditional single-hop LEACH protocols have too high mortality of nodes that are far from the sink nodes. And improved multi-hop LEACH protocols lead nodes that near the sink node are easy to failure because of forwarding too much load. Aiming to solve these two problems, a load balance routing algorithm based on cross-layer power control is proposed. Firstly, the proposed algorithm uses cross-layer power control module to do triangle module fusion judgment between cluster heads' residual energy of physical layer and forwarding load membership of network layer. Then the algorithm optimizes cluster heads' clustering power for building different sizes clusters. At last, cluster heads construct hybrid single-multi hop routing strategy based on the least energy level and find the best transform path. The simulation results show that the proposed algorithm can efficiently balance network load and prolong the network lifetime.
