Abstract
Abstract—The event-driven nature of wireless sensor networks (WSNs) leads to unpredictable network load. As a result, conges-tion may occur at sensors that receive more data than they can forward, which causes energy waste, throughput reduction, and packet loss. In this paper, we propose a rate-based fairness-aware congestion control (FACC) protocol, which controls congestion and achieves approximately fair bandwidth allocation for different flows. In FACC, we categorize intermediate relaying sensor nodes into near-source nodes and near-sink nodes. Near-source nodes maintain a per-flow state and allocate an approximately fair rate to each passing flow. On the other hand, near-sink nodes do not need to maintain a per-flow state and use a lightweight probabilistic dropping algorithm based on queue occupancy and hit frequency. Our simulation results and analysis show that FACC provides bet-ter performance than previous approaches in terms of throughput, packet loss, energy efficiency, and fairness. Index Terms—Congestion control, media access control (MAC), quality of service (QoS), wireless sensor networks (WSNs). I.
