ABSTRACT
The large scale farmland WSN monitoring has the characteristics of wide area and energy constraint. Nodes around sink node undertake lots of data transfer work, so these nodes have the problems of excessive energy consumption and some of them are inclined to early death. This study gives an improved a topology control algorithm for farmland wireless sensor networks based on Yao Graph topology and clustering algorithm. The improved algorithm is aimed to balance the nodes energy in the critical region and prolong the network lifetime by clustering and energy regulatory in the sink node communication range. The simulation results shows that this topology control algorithm is conductive to energy balance in the communication key areas-sink node communication range and at last prolong the nodes and the network life time.
