摘要： 为延长网络生存期，提出一种改进的WSN拓扑控制方法。考虑拓扑控制可能造成的节点负载不平衡问题，利用节点的流量记录对节点能耗情况进行估计，根据网络的实际情况动态调整最低邻居数目。实验证明，在设置有效存活节点比例为90%的情况下，该方法能有效延长网络寿命。

Abstract: This paper proposes a new topology control method that focuses on prolonging the lifetime of WSN. It can prolong the network lifetime based on the information about the residual energy and minimal neighbor number of sensor nodes, which uses sensors’ working record as a metric to estimate their residual energy. Furthermore, LBA-TC can adaptively adjust sensors’ minimal neighbor numbers. The method is evaluated by comprehensive experiments, whose results show that it can significantly prolong the network lifetime.

Key words: topology control, network lifetime, load balancing, residual energy
