Kaixin Xu, Sang Bae, Sungwook Lee, Mario Gerla
2002 Proceedings of the 5th ACM international workshop on Wireless mobile multimedia - WOWMOM '02  
This paper is an experimental study of the unstable behavior of TCP across 802.11 ad hoc networks and the wired Internet.  ...  Yet, when the wired infrastructure (say, the Internet) is within reach, opportunistic connections to Internet sites may be established across the multihop network to transfer files and update databases  ...  Fairness among multiple TCP flows across multihop wireless networks and wired networks is significantly different from that of last hop wireless LAN TCP flows from wired networks to wireless networks usually  ...

Voice Adaptive Gateway Pacer for wireless multihop networks

Dragoș Niculescu, Kyungtae Kim, Sampath Rangarajan, Sangjin Hong
2010 Proceedings of the 5th International ICST Conference on Wireless Internet  
When supporting both voice and TCP in a wireless multihop network, there are two conflicting goals: to protect the VoIP traffic, and to completely utilize the remaining capacity for TCP.  ...  To also maintain utilization and TCP performance, VAGP employs TCP specific mechanisms that suppress certain retransmissions across the wireless multihop.  ...  Suppose the multihop extension is bottleneck in hybrid wired/wireless network. Thus the queueing and network delay in multihop is much larger than the one in the wired part.  ...

Gateway-assisted max-min rate allocation for wireless mesh networks

Kamran Jamshaid, Paul A.S. Ward
2009 Proceedings of the 12th ACM international conference on Modeling, analysis and simulation of wireless and mobile systems - MSWiM '09  
The classical max-min rate allocation is a commonly used fairness criterion in wired networks. Its implications, however, are not well understood in the context of wireless networks.  ...  In this paper we outline various considerations that govern max-min rate allocation in 802.11-based Wireless Mesh Networks (WMNs).  ...  Using ns-2 [1], we simulated a number of network topologies with gateway rate limiting the aggregate TCP traffic it bridges between the wired and the wireless network.  ...

TAiM: TCP assistant-in-the-middle for multihop low-power and lossy networks in IoT

Mingyu Park, Jeongyeup Paek
2019 Journal of Communications and Networks  
We investigate the performance of TCP over multihop many-to-one wireless low-power and lossy networks (LLNs), and present TCP assistant-in-the-middle (TAiM) to improve TCP fairness among LLN endpoints  ...  TAiM is adaptive and flexible to network status, and does not require any modifications to the TCP/IPv6 stack at the endpoints.  ...  TAiM exploits the fact that RTT over multihop LLN is significantly higher and more variable than wired or WiFi networks, especially due to lower bandwidth, higher loss rate, and multihop topology.  ...

Buffer Sizing in 802.11 Wireless Mesh Networks

Kamran Jamshaid, Basem Shihada, Li Xia, Philip Levis
2011 2011 IEEE Eighth International Conference on Mobile Ad-Hoc and Sensor Systems  
We analyze the problem of buffer sizing for TCP flows in 802.11-based Wireless Mesh Networks. Our objective is to maintain high network utilization while providing low queueing delays.  ...  Such delays may affect TCP stability characteristics, and also increase queueing delays for other flows (including real-time flows) sharing the buffer.  ...  Calculating the BDP of a multihop wireless network is different from a wired network because of coupling between the bandwidth and delay of a wireless link [14] .  ...
