Energy Efficient WSN Using Green Task Based Sensing Scheme

Abstract

Wireless sensor networks (WSNs) are widely used to monitor environmental conditions for different purposes with in different locations. However, due to the limited duration of the sensor's energy source, many attempts are made to design energy Efficient WSN. Therefore many outcomes have been presented in literature, such as the adaptation of power, scheduling, sleep and wake up techniques to improve the useful life of the WSN. These techniques are presented separately and shown to achieve some benefits in terms of energy efficiency. In this paper, we present a low-energy efficient design system for WSN that prevents unnecessary wasting of power which in-turn increases the network lifetime. The proposed system reduce the overall power consumption up to 50%-70% approximately as compared to conventional task base scheme which will boost the network lifetime.
