Abstract
According to mobile Ad hoc networks’ self-organizing, multi-hop and dynamic changed topology, these characteristics made it impossible that the technology of traditional wire networks were directly used in Ad hoc networks. In Ad hoc networks, the mobility of Ad hoc node is one of the main reasons of the packet loss, which led to frequent retransmission timeout and a serious impact on the performance of wireless TCP. Based on IEEE802.11, this paper proposes three improvement strategies of TCP performance based on PMAC, PLM and RLM of MAC layer, integrates their respective advantages, and gives a comprehensive improvement solution as MAC-SS. The simulation results show that MAC-SS on the TCP performance in terms of throughput and packet loss rate is significantly improved with the increasing speed of the node.
