Abstract

Wireless Sensor Networks (WSN) consists of large amount of nodes spread either arbitrarily or non-arbitrarily in the region of interest for sensing an event. The main constraint in WSN existence is the consumption of energy by tiny sensor node during operation. For increasing the lifetime of WSN, various clustering techniques have been evolved in the last decade. Energy Consumption by the node primarily depends upon the distance between nodes to Cluster Head (CH), CH to Base Station (BS) and the Length (L) of the packet being transmitted. It has been analyzed that combinations of two different techniques i.e. EECA-F and H-PEGASIS can solve variety of issues. In this paper, two techniques are combined together to form Hybrid Energy-Efficient Clustering Technique (HEECA). Results revealed that in HEECA mechanism, nodes consume 1.75J energy even after 80 rounds whereas in EECA-F the toll reaches 3J. On analyzing, it is found that clustering through HEECA protocol can save 41.7 percent energy in nodes thus making them live longer and eligible to be used in robust applications where replacing battery of a node is a tedious task.
