Mobile Barrier Coverage for Dynamic Objects in Wireless Sensor Networks

Executive Summary

This paper studies Mobile Barrier Coverage (MBC) surrounding dynamic objects. In the real world, several dynamic objects can benefit from MBC. For example, marching troop can detect any adversary intrusion without blind spot by MBC. However, conventional works only focused on barrier coverage for static objects, which fail when the objects start to move. Issues to address these dynamic-object scenarios, the authors propose the problem of mobile barrier coverage for dynamic objects. The most challenge is how to effectively maintain MBC when the motion of objects is unpredictable. They propose a fully distributed algorithm for mobile sensor nodes to cooperatively move and maintain the high-quality barrier coverage.
