摘　　要：结合考虑传统无线传感器网络(wireless sensor networks,WSN)路由协议特点以及实际应用中节点的不对等性,提出了一种自适应负载均衡集簇分层路由协议———ALBCH。该协议在簇头选举时引入剩余能量等相关因子,将贪婪算法成链机制分别引入分层路由协议的簇内通信和簇头间通信,对贪婪算法成链机制进行了一些改进。仿真结果表明,ALBCH能更有效地均衡网络负载,具有更好的健壮性和更高的实时性能,同时解决了传统协议在处理异构网络时的局限性。Considering features of conventional routing protocols of wireless sensor network and the asymmetry of nodes in the practical application, an adaptive loadbalancing, clustering hierarchical routing protocolALBCH is proposed. Based on cluste ring routing protoeals, this protocal introduce residual energy and other related factors into the cluster head election chaining mechanism with greedy algorithm is introduced to communication within clusters as well as among elusterheads some improve ments on the greedy algorithm are finished. The simulation results show that. ALBCH can balance the network load effectively and has better robustness and higher realtime performance while addressing the limitations of conventional protocals in dealing with heterogeneous network.
