Wireless Sensor Networks (WSNs) is mainly characterized by dense deployment of sensor nodes which collectively transmit information about sensed events to the sink. Energy efficiency is a major concern in the design of wireless sensor networks. Due to the spatial correlation between sensor nodes subject to observed events, it may not be necessary for every sensor node to transmit its data. Hence the spatial correlation can be exploited on the Medium Access Control (MAC) layer. The Spatial Correlation-based Collaborative MAC (SCC-MAC) protocol which aims to reduce the energy consumption of the network by exploiting spatial correlation in WSN. Here the number of nodes sending information about an event is decreased by spatial correlation properties.
