A quantitative analysis of TCP performance over wireless multihop networks

Abstract

An analytical model of a single TCP session based on a string topology in wireless multihop networks is presented. The model for the communication process considers buffering, propagation delay and access chance to the channel as well. Markov chain technique is adopted in analyzing the TCP behavior. Fully analysis is given to the case where the TCP source and destination are one hop away and the maximum TCP window size is less than the buffer size in each node. Consideration is also given to the case when the maximum TCP window size is larger than the buffer size in each node. The analytical results are validated against results using the NS simulator.
