A Dual Head Clustering Mechanism for Energy Efficient WSNs

Wireless sensor network are resource constrained. Clustering techniques are used to conserve energy and to prolong the lifetime of the wireless sensor network. A number of clustering techniques have been presented based on single cluster head. In single cluster head mechanisms, the single cluster head is responsible for both data gathering and data forwarding so it consumes more energy compared to the other member nodes and dies earlier. In this paper we propose a Dual Head Clustering Mechanism (DHCM) for wireless sensor network. The DHCM is based on two cluster head, one cluster head selects the data and the other head is responsible for data forwarding set for a specified number of rounds. The simulation results show that the DHCM reduce the overhead over a single head and improves the life time of the network.
