Wireless sensor networks are networks of tiny, battery powered sensor nodes with limited on-board processing, storage and radio capabilities. Sensor nodes sense and send their data toward a processing center called sink. The design of such networks has to be energy aware in order to prolong the lifetime of the network, because the replacement of the embedded batteries is a very difficult process once these nodes have been deployed. In a clustered wireless sensor network the data is forwarded from non-cluster head sensor node to cluster head sensor node.
