| 摘 要： | 针对传感器节点能量受限的特点，提出了一种无线传感器网络中基于负载平衡的多路路由（load balancing multi-path routing,LBMPR）协议．LBMPR依赖传感器节点的地理位置生成从源节点到sink节点的多条路径，数据通信均匀分布于不同路径上，从而达到节点间的负载平衡，延长了网络的寿命．仿真实验表明，若选择适当的参数a和b，较之mesh-2和mesh-3，LBMPR能获得更好的负载平衡性能．

| Abstract: | A load balancing multi-path routing(LBMPR) protocol in wireless sensor networks was proposed because of energy limitation of sensor nodes.Based on geographical location of each node,several paths from source nodes to the sink node could be obtained in LBMPR.Data communications were evenly distributed on different paths,thus load balancing between nodes could be achieved and it also prolonged the lifetime of networks.Simulation results show that LBMPR can obtain better load balancing capability than mesh-2 and mesh-3 by proper selections of parameters a and b. |
