Analysis of coverage problem under border effects in wireless sensor networks
摘要
Abstract
Wireless sensor networks can be used to monitor the interested region by deploying dense sensor nodes. Coverage is a primary metric to evaluate the capacity of monitoring. In this paper, we focus on the coverage problem under border effects, where the sensor nodes are distributed in a circle-shaped region randomly. Under this scenario, we derive the expected coverage of the sensor node and the total network coverage provided by n sensor nodes accurately by probability. These findings are useful to determine the related parameters (sensing range, number of sensor nodes and radius of monitored region) for a specific network coverage ratio. Simulation results demonstrate that our analysis is correct and effective.关键词
