An enhancement of energy centric cluster based routing algorithm for Wireless Sensor Networks

Abstract

Wireless Sensor Networks is a network that can contain thousands of small autonomous nodes that are randomly deployed in an environment to collect data. These nodes are powered with non-rechargeable battery, and it is unrealistic for battery replacement because of the enormous quantity of sensors and expensive cost, nodes may also be deployed in an unfriendly environment. Hence there is the need for algorithms that minimize the energy consumption of nodes, so that the network lifetime can be maximized. we proposed an enhancement of an existing algorithm termed Energy Centric Cluster-Based Routing Protocol for WSNs (ECCR). In ECCR the cluster heads are changed after every round of communication and the current cluster heads serve as a caretaker for selecting the new cluster heads. The frequency of updating the current cluster heads about the prospective cluster heads tend to result in energy waste and also cluster heads nodes may be capable of maintaining the role of cluster head for some few rounds. We focused on extending the lifetime of the network by reducing the frequency of changing cluster heads and updating them on the prospective cluster heads in the network. A simulation model was developed and experiment was conducted to analyse the performance of the proposed algorithm with ECCR. Simulation result shows that the proposed Enhancement outperforms the existing ECCR, in terms of alive nodes, energy dynamics, and stability period.
