The TCP congestion control mechanism along with unfairness problem poses poor performance when IEEE 802.11 MAC protocol is used in multi-hop ad hoc networks because the traditional TCP has poor interaction with the IEEE 802.11 MAC protocol. Because of the greedy nature of TCP, starvation problem of TCP flows with longer paths is severe. In this paper, we first illustrate that the fairness, cong...

This paper assesses whether multi-path communication can help latency-sensitive applications to satisfy the requirements of their users. We consider Concurrent Multi-path Transfer for SCTP (CMT-SCTP) and Multi-path TCP (MPTCP) and evaluate their proficiency in transporting video, gaming, and web traffic over combinations of WLAN and 3G interfaces. To ensure the validity of our evaluation, sever...

In an integrated fiber and wireless (FiWi) access network, multi-path routing may be applied in the wireless subnetwork to improve throughput. Due to different delays along multiple paths, packets may arrive out of order, which may cause TCP performance degradation. Although the effect of packet reordering due to multi-path routing has been well studied, remedy solutions are either to schedule ...

Mobile ad hoc network congestion control is a significant problem. Standard mechanism for congestion control (TCP), the ability to run certain features of a wireless network, several mutations are not common. In particular, the enormous changes in the network topology and the joint nature of the wireless network. It also creates significant challenges in mobile ad hoc networks (MANET), density ...

In recent years, many extensive studies have been performed that have attempted to improve the performance of TCP for wireless networks. The common assumptions made by TCP for wired networks definitely do not hold for wireless networks. TCP with its semantics such as end-to-end flow control, a congestion control mechanism and error recovery provide reliability in wired networks. Wireless commun...

Transmission control protocol (TCP) performance over multi-hop wireless networks is currently attracting considerable interest from the research community. The characteristics of multi-hop wireless networks, such as mobility, link layer contention, high bit error rate, asymmetric path, network partition, hidden exposed nodes and dynamic routing, do not fit the requirements of TCP for a good rel...

Due to the high availability of cheap hardware, wireless multi-hop networks and in particular Wireless Mesh Networks (WMNs) are becoming popular in more and more contexts. For instance, IEEE 802.11 based WMNs have already started to be deployed as means to provide Internet access to rural areas in the developing world. To lower the cost and increase the coverage in such deployments, the wired n...

In Multi-Radio Multi-Channel Wireless Mesh Networks (MRMC WMNs), the performance of TCP significantly deteriorates when non-congestion packet losses occur. TCP-HONC is proposed in this paper to improve the performance of TCP with hoporiented network coding in MRMC WMNs. It combines a block of interand intra-flow packets that share a same next-hop node by random linear network coding, and then i...

The steadily growing importance of resilience-critical Internet applications leads to a rising number of multi-homed sites and systems. But since the protocols of the classical Internet – particularly TCP – assume a single access path only, the number of programs supporting multiple network paths is still small. The Stream Control Transport Protocol (SCTP), which is an advanced general-purpose ...

In this paper, we propose a distributed online traffic engineering architecture for MPLS networks. In this architecture, a primary and secondary MPLS LSP are established from an ingress LSR to every other egress LSR. We propose to split the aggregate TCP traffic between the primary and secondary paths using a distributed mechanism based on ECN marking and AIMD-based rate control. Inspired by th...
