• Recent years have witnessed a stunning rise in the deployment of wireless sensor motes for diverse applications due to its flexibility in sensing real-time monitoring for large scale remote applications. The many-to-one data transmission introduces network congestion/buffer overflow at the sensor gateways that cripples the overall WSN's performance in real time monitoring. In this paper, a new duty cycle based congestion aware algorithm known as Dynamic Agile Congestion Control (DACC) designed to overcome the limitations of FIFO based sensor motes at the gateways. The DACC uses two sub-algorithms one at the gateway that intelligently senses congestion during its initial stage and another at the sensor node that dynamically alters the duty cycle based on packet marking field. The DACC algorithm tested and verified under real-time wireless sensor test bed, results show that the DACC improves the stability, alerts sensor nodes, classify both preemptive and non-preemptive data and reduces congestion control front nodes to the sink node in wireless sensor network.
