Abstract—This work proposes a novel congestion management protocol for constrained delay traffic and optimized rate control for HWSNs. The proposed protocol consists of congestion avoidance and control. We distinguish between high and low priority traffics which are serviced upon their priority and QoS requirements. For high priority traffic, we control end to end delay constrains with node output scheduling weights. For low priority traffics firstly we avoid congestion using a new Active Queue Management (AQM) algorithm that uses distinct virtual queue's situation for a single physical queue in order to decide accepting or dropping the received packets from child nodes. If acceptance occurs for the incoming packet, congestion is detected by the proposed protocol using a three-state machine as well as a virtual queue status. Afterward, child’s sending rate is adjusted using an optimization function. Results of simulation indicate goal achievement for the protocol proposed.
