摘要： Different node layout density exist in farmland wireless sensor network monitoring, but the existing wireless sensor network topology control algorithm does not take uneven node distribution into consideration. And the node residual energy issue is not considered in the commonly used LMST topology control algorithm either. This paper presents a wireless sensor network hybrid topology control algorithm which considered both the uneven distribution of network nodes and the residual energy issue. Firstly, this algorithm clustering in the high node density areas based on node degree to reduce overall energy consumption. Secondly this algorithm use nodes residual energy based LMST topology control algorithm to achieve energy balance among network nodes. This improved algorithm ultimately achieved the purpose of prolonging the network lifetime.
