TCP Performance over a contention based wireless multi-hop network

In this study we analyze the performance of TCP over a simulated multi-hop wireless network based on network topology and background traffic derived from held experiments. The channel access is a Multiple access Collision Avoidance (MACA) type protocol, with link level acknowledgements, and a network topology based on cluster formations that include a cluster "head" through which inter-cluster traffic is transmitted, We measure the throughput for the cases of one, two and three hops as well as the effect it has on the background traffic completion rate We also investigate the performance of multiple Ne transfers performed in parallel Finally we investigate different TCP parameters in an attempt to optimize the performance.
