Abstract: In a wireless sensor network,the sink’s neighbor nodes have to withstand enormous traffic load in forwarding data,and these nodes run out of their battery power very soon.It is prone to be energy hole problem,thus this zone becomes a communication bottleneck for the whole wireless sensor networks.In order to save energy in the bottleneck zone,the paper proposed the TRNC strategy.It properly adjusts the transmission power range of nodes in the bottleneck zone by analyzing the impact of the transmission power range of the nodes on energy consumption,at the same time,it combines the network coding method.Theoretical analysis and numerical simulation results show that the strategy can effectively improve the energy utilization efficiency and reduce the energy consumption.
