Energy Optimization in Wireless Sensor Networks using Duty-cycling Approach

摘要

Developing sustainable wireless sensor networks (WSNs) poses a unique challenge in terms of estimating the trade off between autonomous sensor network operations and accessibility to constrained power resources. WSNs are expected to be operational for prolonged periods with minimal intervention. However, this imposes substantial cost in terms of power (battery) requirements in WSNs. Under several practical conditions, it may not be feasible to change or recharge these battery powered systems, limiting the availability of usable power. To ensure judicious power utilization and improved life expectancy of WSNs, energy optimization is crucial. In this work, a loose-TDMA based duty-cycling approach is proposed for achieving power efficiency in sensor networks.
