Non-uniform deployment strategy of wireless sensor networks based on path

The unbalanced load among sensors in wireless sensor networks is caused by many-to-one way of data transmission.The nodes near Sink will spend more energy than those far away from Sink,and then the energy hole is caused in sensor networks.According the paths of data transmission and the nodes undertaking the different number of paths,the energy consumption of different layers node is balanced.The non-uniform sensor deployment strategy,which number of routing node in an inner is equal to number of sensing node in outer tiers farther away from Sink,while the fraction of coverge of sensing node in all the coverage area is the same,is presented.The simulation results show that the non-uniform sensor deployment strategy is feasible.
