Optimization and lifetime anticipation for WSN using fuzz logic
S Suganya, D Padmaja, Yaram Swarna Latha · 2016
WSN is a network in which sensors are distributed randomly in space to keep track of any environmental or physical conditions. The uses of WSN is innumerable. Energy conservation and enhancing network lifetime are always been a challenging task. In this paper, to conserve energy and to maximize lifetime, FLC_1 and FLC_2 are used which dynamically regulates transmission power and sleep time. An IEEE 802.15.4 standard network is used. The main aim is to dynamically change transmission power and sleep time to maximize the battery life of the devices. And, finally by using fuzzy logic control FLC, we can calculate the lifetime by using RPS, STR and TTR. MATLAB simulations show that the lifetime of the device is increased by more than 30% when compared with fixed sleep time and fixed transmission power and by using fuzzy logic lifetime prediction, its lifetime is predicted.
