Adaptive duty-cycle based congestion control for home automation networks

There is a growing interest in the wireless sensor network technology in the home automation field, but as the number of sensor nodes in the home increases and as the data traffic generated by such nodes grows, the network becomes more congested. Due to resource constraints, a congestion control scheme for wireless sensor network should be designed with simplicity and operate energy efficiently. In this paper, we propose ADCC(Adaptive Duty-cycle Based Congestion Control), a lightweight congestion control scheme using duty-cycle adjustment for wireless sensor networks. This scheme uses both the resource control and traffic control approaches according to the amount of network traffic for the congestion avoidance. Our simulation results show that the ADCC improves the reliability and energy efficiency of duty-cycle based congestion control in wireless sensor networks.
