A Duty Cycle Adaptive Algorithm Based on Throughput

For wireless sensor networks, the duty cycle is an important factor to energy benefit, by analyzing how the listening/sleep periods of S-MAC, T-MAC protocol work on energy consumption, we have defined two parameters, Th
_fl
and Q, Th
_fl
standing for average wave of network traffic, Q named as throughput quality factor. They reveal the relations among duty cycle, throughput, and energy consumption. Thus, we design a duty cycle adaptive algorithm based on throughput. The results show it is effective.
