Abstract: Aiming at the problem of unbalanced load for nodes in Wireless Sensor Network(WSN), a load-balanced Topology Control(TC) algorithm is proposed, which makes nodes as data transmitting nodes and makes the distance between two nodes and residual energy of nodes as the foundation of setting up the topology. The nodes with low energy are given node degree, which balances the network load, solves the problem that the energy consumption of some nodes in network is too fast due to over load of nodes, and extends the network lifetime.

摘要： 针对无线传感器网络节点能耗分布不均匀的问题，提出一种负载均衡的拓扑控制算法，该算法将节点看作数据转发节点，把节点间距离和节点剩余能量作为拓扑构建的依据，对剩余能量较少的节点赋予一定的节点度约束，从而均衡网络负载，解决网络中部分节点因负载过重而导致的能耗过大问题，有效延长网络生命期。
