Utilising coverage holes and wireless relays for mobile target tracking

Coverage holes are usually considered as harmful in wireless sensor networks. Many sensor deployment strategies and coverage recovery algorithms have been proposed to improve the sensing coverage and remove detected coverage holes. However, in many situations, full coverage can not be guaranteed or consistently maintained throughout the network lifetime. Moreover, in certain applications, full coverage is not possible or unnecessary. In this paper, we introduce SmartRing, a distributed target tracking strategy that utilizes the coverage holes in sparse network or network partition. Sensor nodes not only act as communication relays, but also take part in aiding path planning of pursuer robot. Sensors forming the ring of a coverage hole gather and provide target information to the pursuer. Once a target is detected, sensor mobility or activity is coordinated such that the pursuer benefits from the variable size of the coverage hole that act as a trap. We perform simulation study to evaluate how feasible and efficient the proposed strategy is running in different modes.
