Analysis of Energy Efficient Wireless Sensor Networks Routing Schemes

Wireless Sensor Network (WSN) is one of the fastest growing technologies in wireless domain. The sensor nodes are typically lightweight and with limited battery power they are failure-prone too. So, efficient power saving schemes must be designed and developed to optimize energy consumption and thereby improve overall network lifetime. Clustering technique is one of the time-tested approaches that effectively reduce energy consumption. The lifetime of WSNs is enhanced by uniform clustering that balances network load among the clusters. In this paper, we have reviewed various energy efficient clustering schemes applicable in wireless sensor networks. The schemes are analyzed thoroughly and some of them are simulated to assess performance.
