Abstract:
In sparse deployments of mobile sensors, the mobility of sensors is required to search the coverage area in an attempt to achieve polling—complete, possibly repeated, area coverage over time. Mobile sensor platforms are vulnerable to a variety of hazards during normal operation. When sensors lose the ability to mobilize due to mechanical failure, environmental factors, or simply exhausting their energy source, coverage effectiveness can be seriously impacted. Ideally, algorithms should adjust their behavior to compensate for failure modes in order to avoid areas statically covered by disabled sensors as well as adjusting their behavior to cover the areas assigned to sensors that are no longer able to mobilize. In this work, we demonstrate the effects of disabled mobility on area coverage algorithms due to their inability to adjust behavior, and suggest mitigation strategies and the impact on improving coverage in the face of disabled mobility.
