Wireless Network Coverage and Power Assignment

In wireless sensor networks, maintenance the network coverage is one of the most important tasks to guarantee the quality of monitoring results. There are many factors that affect the coverage of wireless sensor networks. In the deploying phase, the full coverage may not be achieved because of random deployment. Then in the operation phase, some sensors may stop working due to the energy depletion or malfunctions. If we have redundant mobile sensor in the monitored area, we can schedule them to necessary locations that set up the coverage. The scheduling algorithm should be fast and light because the resource of sensors is very limited.


  • Propose the quality measure to evaluate the coverage quality of wireless sensor networks
  • Design fast and light movement scheduling algorithm that relocate mobile sensors to guarantee a specific coverage quality
