Abstract :
We report the so-called "TCP instability problem" in 802.11-based wireless mobile multi-hop networks. Our results show that the throughput performance of multi-hop TCP traffic in such a network may suffer from severe oscillation. By illustrating the multi-layer traces, we show that this problem is rooted in the MAC layer. Furthermore, a resolution is proposed to eliminate this problem.
