Trade-Off Between Mobile Node Density and the Detection Performance in Mobility-Assisted Sensor Networks
Source: University of New Mexico
In this paper, stationary target detection in a hybrid sensor network consisting of both static and mobile nodes is considered with random node mobility models. Static nodes and mobile nodes (initially) are assumed to be deployed independently and randomly in the sensing field. Mobile nodes are exploited to compensate for the lack of coverage provided by static nodes, and subsequently a time varying coverage improvement is achieved. The authors evaluate the detection performance of the hybrid network analytically based on geometric probability. They consider two sensing models: single-sensing detection and multiple-sensing detection.
