Wireless sensor networks consist of a large number tiny sensors that have only limited energy supply. One the major challenges in constructing such is to maintain long network lifetime as well sufficient sensing area. To achieve this goal, broadly-used method turn off redundant sensors. In paper, problem estimating areas among neighbouring wireless analysed. We present an interesting observation concerning minimum and maximum neighbours are required provide complete redundancy introduce simple methods estimate degree without knowledge location or directional information. also tight upper lower bounds on probability average partial redundancy. With random deployment, our analysis shows more realistic for real applications, expensive, requiring up 11 90 percent chance Our results can be utilised designing effective scheduling algorithms reduce consumption mean time reasonable
