基于负载均衡的无线传感器网络路由算法

摘要

延长网络的稳定周期是无线传感器网络路由算法的重要挑战,负载均衡算法是解决上述问题的重要方法之一.提出了一种负载均衡算法(LDBRA),它根据节点的能量分布状况及通信能耗选择簇首节点以实现负载均衡.在簇首选择过程中,在以上两个因素中选择平衡点实现最优簇头的选择.仿真结果显示LDBRA能够更好的实现负载均衡,延长网络的稳定周期.%It is a challenge to prolong the stable period in wireless sensor networks. Load balance routing algorithm is one of the solutions to the problem. The paper proposed a load balance routing algorithm(LDBRA), which select cluster head nodes and implement load balance according to the condition of energy distributing and the communication cost to prolong the network lifetime stable period. In the process of cluster head selecting, based on the above two factors to select optimal cluster head nodes. Simulation results show that the LDBRA could better implement load balance and prolong the network stable period.
