| 摘 要： | 为了提高无线传感器网络的能量利用率和延长网络的生命周期,本文提出了基于负载平衡的无线传感器网络路由算法。首先,将网络划分成多个网格,根据网格内节点的负载情况定义网格的状态,结合网格的地理位置和网格负载状态选择路由网格;其次,根据节点剩余能量和负载大小在选择的网格内选取一个合适的节点开始数据的收发工作;最后,通过模拟实验将本文算法与GPSR算法和GEAR算法进行比较。仿真结果表明,该算法有效改善了网络的负载均衡,延长了网络的生存期,并提高了网络的吞吐量。

| Abstract: | A load balanced routing algorithm for wireless sensor networks is proposed to improve energy efficiency and extend the network life cycle.The paper proposes a wireless sensor network routing algorithm based on load balancing.Firstly,the network is divided into multiple grids in the form,and then defines the state of the grid nodes within the grid-loading,select the routing grid with the grid location and grid load status.Then,according to the node residual energy and load size selected within the grid,an appropriate node is selected to transmit data.Finally,the author compares the proposed algorithm with GPSR algorithm and GEAR algorithm through simulation experiments.The simulation results show that the algorithm is effective to improve the network load balancing,and extend the survival time of the network and improve network throughput. |
