Abstract

In this paper, we investigate the problem coming from the adaptation of legacy protocol TCP to the cross-layer protocols that is likely happen in future Internet. We point out named a TCP starvation problem in combining TCP and max-weight scheduling of cross-layer algorithms in wireless mesh networks. TCP starvation occurs when neighbor nodes are already scheduled with large queue length. To overcome TCP starvation as denoted in this paper, we propose a simple remedy named fake-ACK algorithm.
