Title: Queueing delay-based congestion control technique for seamless routing in WRSN
Abstract: Congestion in Wireless Sensor Network (WSN) and Wireless Rechargeable Sensor Network(WRSN) can significantly impact network performance. It is essential to find a congestion control policy that minimizes congestion while maximizing throughput and bandwidth utilization. Existing solutions use either a loss-based approach which depends on timeout or duplicate acknowledgements, or a delay-based approach which depends on RTT. These solutions detect congestion only after it has occurred but does not prevent it. Thus, it is important to have a congestion policy that can detect or forecast an upcoming congestion scenario and try to prevent it. In this paper, an Queueing Delay-based Congestion Control Technique(QDCCT) is proposed that prevents congestion before it occurs and thus maximizes throughput and minimize overhead. The proposed technique takes into account both its own data flow and other background flows to identify congestion level. With the aid of run time metrics such as RTT, queueing delay variation and congestion window growth factor, the proposed algorithm prevents /resolves the congestion on the network thus allowing more packets to be transmitted with minimal delays and losses. The proposed TCP variant has been simulated and the solution has been evaluated and analyzed with the existing algorithms in terms of throughput, goodput, Packet Loss Ratio(PLR) and Packet Loss Ratio(PDR).
