Abstract

SummarySensor deployment is a fundamental issue in Internet of things. In this paper, It addressed the problem of how to effective deployment for prioritized event area in mobile sensor networks with low density sensors, which coverage completely cannot be realized. When event areas have been detected, the problem how to make mobile nodes moved to a suitable place with effective deployment is studied. Firstly, a coverage weight by priority function of event area is defined. It deduced conclusion that coverage effectiveness have maximization as if all of nodes coverage weight are identical. A nodes deployed strategy have presented that combined coverage weight and virtual force. Finally, some simulations shown that the proposed deployment algorithm are accurate and effective.
