Abstract

Wireless Sensor Networks (WSN) comprise of a large number of sensor nodes that have very limited energy in them. The sensor nodes are deployed in certain places in order to monitor Temperature, Pressure, Sound and other environmental conditions also. Wireless Sensor Networks are widely used in various fields such as medical, industrial monitoring, military surveillance and much more. The nodes in the network need to transfer data continuously to the Base Station and they have very limited energy in them. As a result of which the energy of the nodes decreases as the data gets transferred. It is not an easy task to replace the batteries of the nodes at all times, hence energy efficiency plays a very important role in Wireless Sensor Networks in order to increase the lifetime of the nodes present in the network. This paper deals with the energy efficiency in Wireless Sensor Networks to minimize energy consumption of the nodes. The Multi-hop Chain Routing Algorithm using a Dynamic Coordinator (MCRA-DC) considers various factors like transmission distance, data volume that needs to be transmitted and the energy residue of the nodes to select the path for transferring data from the nodes to reach the Base Station (BS). This algorithm also ensures that the network is available for a longer time by a frequent update of the Cluster Head (CH) and the path to reach the BS. The proposed technique thus increases the entire performance of the network in aspects of increasing the lifetime of sensor nodes.
