Aiming at the problem of energy hole in linear wireless sensor networks, a non-uniform deployment scheme of energy consumption equilibrium in linear wireless sensor network is proposed. The scheme proves that in addition to the sub-monitoring area furthest from the Sink node, the remaining sub-monitoring area can achieve network energy consumption balance when the number of sensor nodes in it increases equally from far to near, and a sufficient number of relay sensor nodes need to be randomly deployed to forward data. The simulation results show that the proposed scheme can effectively solve the problem of energy hole, make the linear wireless sensor network can achieve the goal of balanced energy consumption, and greatly extend the life of the network, which is of great significance for improving the performance of the actual linear wireless sensor network.
