WSN has the potentiality to join the physical world with the virtual world by creating a network of sensor nodes. Here, sensor nodes are usually battery-operated devices, and hence energy reduction of sensor nodes is a major design issue. To extend the network's lifetime, minimization of energy consumption should be used. In cluster-based routing, cluster heads shape a wireless stamina to the sink. Each cluster heads collects data starting the sensors belonging to its cluster and ahead it to the sink. Here, the cluster head position rotates, i.e., each node works as a cluster head for a restricted period of time.
