Optimizing Duty-Cycle for Delay and Energy Bound WSN Applications,

Pardeep Kumar, Mesut Güneş, Qasim Mushtaq, Jochen Schiller— 2010

Despite their limited resources, especially energy, wireless sensor networks (WSNs) are being accepted in many application areas. This makes them a challenging yet an appealing research area. Evidently, a lot of research work revolves around energy efficiency in order to prolong WSNs lifetime. A prominent amount of work suggests keeping radios of sensor nodes in low power sleep mode for most of the time. However, this duty-cycling results in increased network latency. Selection of an optimal duty-cycle is always challenging especially for applications where latency, along with energy consumption, plays an important role. This paper evaluates AREA-MAC for delay, energy, and packet delivery ratio factors for several duty-cycle values. AREA-MAC is a medium access control (MAC) protocol designed for realtime and energy-efficient WSN applications. Linear optimization is used to find the optimal value of duty-cycle in order to minimize delay and energy consumption and by keeping packet delivery ratio above a certain threshold.
