Energy Efficient data collection through Double Cluster Heads in Wireless Sensor Network

Wireless sensor network is the revolution in the sensors applicability in the modern era. Almost every sector is influenced by the wireless sensor networks. The one of the major constraint in the WSN is the limited battery resources. The efficient routing techniques have to be developed to take concern of the network lifetime. There have been various routing strategies aiming to enhance network lifetime. In this paper, we have proposed the two levels of Cluster Heads (CHs) in each cluster to make the data forwarding much efficient towards the Base Station (BS). By employing two cluster heads, the load of single CH is distributed with the other one. Main CH (MCH) will collect the data from the assistant CH (ACH) and then it will be forwarded to the BS or to the other MCH. Results in MATLAB shows that the proposed protocol has given the much enlarged network lifetime
