In Wireless sensor networks, various energy saving techniques have been proposed and implemented to improve the effective lifetime of the network. Connectivity and coverage of a wireless network must be maintained for the longevity of sensor network along with the energy conservation. In this paper, we will present the concept of energy saving through topology control protocols while providing complete connectivity and coverage. We will go through some topology control protocols like GAF, PEAS and their improvement to analyze how the improved protocol will increase effective lifetime of the wireless network.
