Research and simulation of transport protocols optimization on wireless multi-hop networks

摘要

It will encounter problems when traditional transport protocols are applied in wireless multi-hop networks (WMNs). Stream Control Transmission Protocol (SCTP) has the potential to be an alternative transport protocol that may be able to better satisfy the requirements of WMNs than traditional protocols, TCP and UDP. In this paper, we analyze and simulate the impact of some factors on the performance of transport protocols on WMNs. (e.g., hops, CWmin, packet size and maximum window of TCP, chunk size of SCTP). Moreover, via extensive simulations of four transport protocols (TCP, SCTP, UDP and DCCP) in competition scenarios, we analyze the relationship between network performance (e.g., throughput) and network factors. And we propose optimization methods with proper values of factors. The results of simulations also can be used as the foundation of further studies on transport protocols on WMNs.
