In spatial correlated sensor networks, nearby sensor nodes show a high degree of similarity in their readings. Keeping this in mind, the monitored region is divided into clusters and one cluster head is assigned to a cluster which does the sensing work while other nodes are in sleep state. This results in considerable energy savings as only one cluster head representing other nodes in the cluster does the sensing and transmitting work. In this paper, a framework is proposed to add functionality to existing networks so as to increase the networks lifetime and also aid in better tracking of unusual phenomena such as forest fires.
