Executive Summary

In this paper, the authors, based on NS-2 simulator, evaluate the performances of different TCP protocols with network coding in wireless multihop networks, and then propose two schemes to enhance the performances of TCPs with network coding. In particular the network coding scheme considered and used here is COPE, which is one of the well-known practical network coding schemes, the TCP protocols evaluated are TCP-NewReno, TCP-FeW and TCP-AP, and the TCP protocols with COPE are implemented in NS-2. The simulation results show that COPE performs very differently in improving the performances of the TCP's in different wireless network topologies.
