A congestion control scheme for (m, k)-firm realtime streams in wireless sensor networks

In this paper, we design an (m, k)-firm[1] based realtime congestion control scheme to make the prior protocol be able to handle both link-level and node-level congestions during packet transmissions. Simulation results show that for real-time applications, the proposed congestion control scheme could effectively avoid dynamic failures and guarantee end-to-end QoS requirements.
