ABSTRACT
Wireless sensor networks (WSN) encounter spatially-correlated traffic due to high density of node deployment that is commonly found in detection and tracking applications. Due to spatial correlation among readings of nodes that are observed by a single event, it is not compulsory for every sensor node to transmit its informations to the distant sink node. This paper aims by exploiting the broadcast nature of wireless channel for conserving the energy in spatially-correlated WSN. The reporting energy of an event depends on following factors asresidual energy of node, number of nodes reporting a detected event, and the frequency of occurrence of an event. The collaborate nature of event reporting using multiple nodes reduces power consumption and hence overall network life time will increase. We show that 30 % to 50 % energy saving is achieved by minimizing the redundant information in spatially-correlated WSN.
