Energy Efficient Approach for Multi-level Routing in Wireless Sensor Networks

Abstract

The wireless sensor network is the decentralized kind of network which allows sensor nodes to join or leave the network according to their wish. The implementation of sensor network is done at far places, and they are small sized. Thus, energy consumption becomes the main issue of WSN. The data, whose collection is done from the aimed environment, is transmitted directly to the main station due to the restricted energy of sensor nodes. The sink node receives the data transmitted from various sensor nodes. The decision-making process is deployed by recognizing and eliminating the similarity among the data of diverse sensor nodes. In addition, the sink makes the deployment of obtained data locally as well as transmits these data to the networks which are executed far away. The existing research work employs CTNR, an energy efficient protocol that is capable of enhancing the duration of WSN.  The CTNR protocol is consisted of two-level hierarchies for mitigating the energy consumption of wireless sensor network. The CTNR protocol selects the CHs (cluster heads) in the network based on the distance and energy. This research work will focus on enhancing the CTNR routing algorithm so as the life span of network can be prolonged.
