| Abstract(in English) | In this paper, we discuss a topology-dependent unfairness problem of TCP in multihop wireless networks. In a multihop wireless network where several TCP flows cross the same intermediate node, these TCP flows may have different throughput performance even when they have the same end-to-end hop count. This unfairness depends on the hop count from the source node of each TCP session to the shared intermediate node. We first confirm the problem by evaluating the TCP performance in a simple simulation scenario that two TCP flows with the same hop count share the same node. Next, to solve the problem, we propose a packet discarding technique that the shared intermediate node randomly discards TCP packets with a probability depending on its hop count to each TCP source node. With several simulation scenarios, we validate the effect of the proposed technique. |
