A wireless sensor network is a group of self powered specialized sensor nodes with a communications infrastructure to monitor and record conditions at diverse locations to cooperatively pass their data through the network to a main location. In any WSN application and the main challenge faced is the energy consumption during discovery of the network, acquisition of data, communication between the nodes and during data processing. However an inefficient network discovery consumes more energy than all other tasks. Many algorithms aim to reduce the energy consumption through clustering and dynamically allocating the Cluster Head (CH). The Cluster Head in turn will send conformation to the nodes in close vicinity and the nodes respond to indicate their participation.
