Adaptive Duty Cycle Algorithm for Large Scale Wireless Sensor Networks

Abstract

In wireless sensor network, energy consumption is one of the most important issues. For every application like monitoring temperature, humidity and pressure, sensor nodes need to keep active which consumes lot energy. The nodes once deployed are not easily replaceable and rechargeable. So, adapting duty cycle of sensor node is a good idea to reduce energy consumption. The duty-cycle is a method that periodically repeats sleep and wake periods. The goal of this research is to design adaptive duty cycle algorithm for wireless sensor networks that minimizes energy usage. The algorithm is designed for both high as well as low traffic so that performance of network can be analyzed under variable traffic load. In this, the sleep time of node will be adjusted in such a way that it should get active only when there is event in the network. Due to its adaptive nature, the energy consumption will be lesser which will help improves network lifetime.
