Duty Cycle Adaptation with Respect to Traffic

Energy is a scarce resource in wireless sensor networks. During deployment an appropriate duty cycle to adjust the trade-off between energy consumption and transmission delay has to be found. In this paper an adaptation algorithm for the duty cycle is proposed. Thereby, the traffic originating from sensor nodes is monitored in the relay node. Subsequently, the relay node evaluates the traffic wether the duty cycle has to be changed. In this paper the algorithm is evaluated in static and dynamic scenarios. It reveals that the algorithm can adapt to changing traffic, depending on the parametrization of the adaptation. The proposed adaptation algorithm saves energy in applications with strong requirements according to energy consumption. 1
