    Abstract
  • Coverage holes often appear in wireless sensor networks due to sensor failure or the inheritance of sensor's random distribution. In the hybrid model, mobile sensors in the network are acquired to heal coverage holes by their mobility. When multiple coverage holes appear in the sensor network and each of them has a time requirement (in which the coverage hole has to be healed), conflicts for the requests of the same mobile sensor may arise. A distributed multiple mobile sensor scheduling protocol (DMS) is proposed in this paper to solve this problem by finding mobile sensors in the time response zone defined by the time requirement of each coverage hole. Simulation results show that DMS can well schedule the mobile sensors to move to multiple coverage holes within the time requirement.
