One of the fundamental services provided by a Wireless Sensor Network (WSN) is the monitoring of a specified Region of Interest (RoI). Considering the fact that emergence of holes in the RoI is unavoidable due to the inner nature of WSNs that includes random deployment, environmental factors, and external attacks. Assuring that the RoI is completely and continuously covered is very important. This paper seeks to address the problem of these holes in the RoI and healing them.
