Abstract
Most traffic in the real internet is TCP traffic. Therefore newly proposed network coding schemes must consider their effects on TCP performance. However, in most studies on network coding, performance evaluation has been conducted using other types of traffic than TCP traffic because network coding has effects on the pattern of packet transmission, which again can impact TCP performance. In most packet transmission schemes based on network coding for wireless mesh networks, it is determined which node, among the ones that received a broadcasted packet, should encode and forward it. In this paper, we examine how the forwarder nodes impact TCP performance.
