Shilpa Mahajan, Dr. Jyoteesh Malhotra . Energy Efficient Control Strategies in Heterogeneous Wireless Sensor Networks: A Survey. International Journal of Computer Applications. 14, 6 ( February 2011), 31-37. DOI=10.5120/1886-2503
Wireless sensor networks (WSNs) have received tremendous attention in recent years because of the development of sensor devices, as well as wireless communication technologies. It is usually randomly deployed in inaccessible terrains, disaster areas, or polluted environments, where battery replacement or recharge is difficult or even impossible to be performed. For this reason, network lifetime is of crucial importance to a WSN. In this article we present a survey of various energy efficient techniques in a heterogeneous wireless sensor network .We first outline the basic network radio model and how this model can be used to study various trades off between network deployment costs, clustering approach in terms of energy efficiency. We also high lights some energy efficient protocols that can be used in heterogeneous networks.
