Several anomalies can occur in wireless sensor networks that impair their desired functionalities i.e., sensing and communication. Different kinds of holes can form in such networks creating geographically correlated problem areas. Hole problem is a crucial issue in Wireless Sensor Network (WSN). Nodes near the sink region will die sooner from outer sub-regions because these nodes send their own data as well as forward outer sub-regions data to the sink. So after very short time energy hole comes near the sink region.
