This paper studies TCP performance over multihop wireless networks that use the IEEE 802.11 protocol as the access method. Our analysis and simulations show that, given a specific network topology and flow patterns, there exists a TCP window size W , at which TCP achieves best throughput via improved spatial channel reuse. However, TCP does not operate(More)
This paper studies TCP performance in a stationary multihop wireless network using IEEE 802.11 for channel access control. We first show that, given a specific network topology and flow patterns, there exists an optimal window size W* at which TCP achieves the highest throughput via maximum spatial reuse of the shared wireless channel. However, TCP grows(More)
Transport protocol design for supporting multimedia streaming in mobile ad hoc networks is challenging because of unique issues, including mobility-induced disconnection, reconnection, and high out-of-order delivery ratios; channel errors and network congestion. In this paper, we describe the design and implementation of a transmission control protocol(More)
Transport protocol design for mobile ad hoc networks is challenging because of unique issues, including mobility-induced disconnection, reconnection, and high out-of-order delivery ratios; channel errors; and network congestion. In this work, we describe the design and implementation of a TCP-friendly transport protocol for ad hoc networks. Our key design(More)
As an efficient distribution mechanism, peer-topeer technology has become a tremendously attractive solution to offload servers in large scale video streaming applications. However, in providing on-demand asynchronous streaming services, P2P streaming design faces two major challenges: how to schedule efficient video sharing between peers with asynchronous(More)

Transport protocol for supporting multimedia streaming in mobile ad hoc networks has to cope with the rich dynamics, including mobility-induced disconnection, reconnection, and high out-of-order delivery ratios; channel errors; and network congestion. In this work, we describe the design and implementation of ADTFRC, a TCP-friendly transport protocol for ad(More)
We develop a framework of <i>distributed</i> and <i>stateless</i> solutions for implicitly given packing linear programs, which are solved by multiple agents operating in a cooperative but uncoordinated manner. This is motivated by multi-commodity flow problems where flows can be split along possibly exponentially many paths. Compared to explicitly given(More)
