摘　　要：针对网络节点路由策略的不合理而引起的"热点"问题,提出一种基于D EEC协议的负载均衡路由算法E ADEEC.该算法采用簇间多跳、多路径的路由策略来构建均衡路由树,并对节点多的子路由树进行局部调整以进一步优化处理,避免热点因负荷太大而提早死亡,从而延长网络生存时间.仿真结果表明,相对于L EACH和DEEC,EADEEC的负载均衡性以及生存时间有明显改善.Aiming at the problem of“hot spots”caused by the network node unreasonable routing strategy, a load balancing routing EADEEC algorithm based on DEEC protocol is proposed. This algorithm adopts the multi hop and multi path routing strategy between clusters to construct the balanced routing tree, and makes local adjustment for sub routing tree which has more nodes to further optimize so as to avoid premature death of“hot spots”due to overload and to prolong the network survival time. The simulation results show that the load balance and the survival time of EADEEC are significantly improved compared with LEACH and DEEC.
