Improve TCP Performance in Ad Hoc Netwoks
نویسندگان
چکیده
Standard TCP misinterpret mobility loss in Ad hoc network as congestion loss, thus, it reduce the TCP performance by invoking unnecessary congestion control action. In this paper, we propose two approaches, simELFN (an variation of TCP-ELFN) and TCP-FSR (an variation of TCP-F). They can distinguish the essence of packet loss and avoid multiple consecutive dupACKs. Analyses and simulations show that they can achieve better TCP performance in Ad hoc network.

TCP Contention Control: A Cross Layer Approach to Improve TCP Performance in Multihop Ad Hoc Networks
It is well known that one of the critical sources of TCP poor performance in multihop ad hoc networks lies in the TCP window mechanism that controls the amount of traffic sent into the network. In this paper, we propose a novel cross layer solution called “TCP Contention Control” that dynamically adjusts the amount of outstanding data in the network based on the level of contention experienced ...
متن کاملTCP-aware Source Routing in Mobile Ad Hoc Networks
Temporary link failures and route changes occur frequently in mobile ad hoc networks. Since TCP assumes that all packet losses are due to network congestion, TCP does not show satisfactory performance in ad hoc networks. In this paper, we propose a simple and new mechanism called TSR, TCP-aware Source Routing, which can improve TCP performance in mobile ad hoc networks. By reducing the number o...
متن کاملA Survey on Tcp over Mobile Ad-hoc Networks
This chapter is a survey on TCP performance in mobile ad-hoc networks. We first describe the problems of standard TCP in ad-hoc networks, and then present the design space and existing solutions to improve TCP throughput. Particularly, we use a detection-response framework to categorize different approaches and analyze the possible design options.
متن کاملTCP performance over mobile ad hoc networks: a quantitative study
In this paper we study the performance of TCP over mobile ad-hoc networks. We present a comprehensive set of simulation results and identify the key factors that impact TCP’s performance over ad-hoc networks. We use a variety of parameters including link failure detection latency, route computation latency, packet level route unavailability index, and flow level route unavailability index to ca...
متن کاملA survey of performance enhancement of transmission control protocol (TCP) in wireless ad hoc networks
Transmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well. Compared to wired networks, wireless ad hoc networks have some specific characteristics such as node mobility and a shared medium. Owing to these specific characteristics of wireless ad hoc ne...
