| Abstract(in English) | A proper load control mechanism is necessary to satisfy traffic qualities in terms of throughput, delivery ratio, delay, and so on. In the internet, the end-to-end flow control mechanism of Transmission Control Protocol (TCP) has been used as the major scheme to restrain traffic sources from overloading the network. However, in multi-hop wireless networks, TCP's flow control suffers from poor performance, implying the fact that the end-to-end scheme is not the best solution. In this paper, we propose a hop-by-hop load control scheme that consists of queue monitoring, inter-/intra-node backpressure rate signaling, and upper-/lower-layer rate control. By providing a unique queue structure and rate control mechanisms at the link and application layers, the proposed scheme can promptly react to the wireless channel dynamics and tunes load condition according to control requirements such as congestion control and/or delay control. By simulations, we evaluate performances of the proposed scheme and show that the proposed scheme provides approximately 100% of packet delivery ratio and at most 3 times higher throughput than that of the conventional scheme. |
