Effect of Duty Cycle on Energy Consumption in Wireless Sensor Networks

Most studies define a common duty cycle value throughout the Wireless Sensor Networks (WSNs) to achieve synchronization among the nodes. On the other hand, a few studies proposed adaptation of the duty cycle according to uniform traffic conditions to decrease the energy consumption and latency. In this paper, the lifetime of the nodes based on overall energy consumption are estimated and the effect of duty cycle on expected energy consumption is studied. The proposed scheme is compared with a standard scheme and is shown to perform significantly better for sufficient node density.
