Low Delay Marking for TCP in Wireless Ad Hoc Networks

Overview End-hosts on wireless ad hoc networks typically use TCP as their transport layer protocol. Being designed for wired networks, TCP can perform poorly over wireless networks. Work that has proposed ways to improve TCP performance over wireless networks has concentrated primarily on improving TCP throughput only. Emerging applications, such as interactive multimedia and network games, require reduced delay at least as much as increased throughput. This paper proposes LDM1, an IP layer queue marking mechanism that estimates the number of hops and flows at each wireless node to computes the optimal marking probability. Simulation results and analysis is presented that demonstrate that LDM greatly reduces the round-trip time of TCP connections while improving throughput under many configurations.
