Any communication network has a finite traffic capacity and if it is offered traffic beyond the limit it must reject some of it. The data-communication network studied here is one employing packet switching, like the Advanced Research Project Agency (ARPA) network. It handles blocks of data, called packets, and longer messages are subdivided, rather in the same way that store in a computer is a...

This paper describes a tool for characterizing the TCP behavior of a remote host on the Internet. The tool allows the researcher to manipulate TCP communication with a remote TCP. The specific goal in building this tool was to answer the question “What fraction of web servers use NewReno instead of Reno or Tahoe TCP congestion control mechanisms, for TCP connections with non-Sack-enabled client...

MANET (Mobile Ad-hoc network) forms a temporary network of wireless mobile nodes without any infrastructure where all nodes are allowed to move freely, configure themselves and interconnect with its neighbors to perform peer to peer communication and transmission. TCP (Transmission Control Protocol) offers reliable, oriented connection and mechanism of end to end delivery. This article provides...

Widespread deployment of multicast depends critically on the existance of congestion control protocols that are provably fair to unicast traffic. In this work, we present an optimization-based congestion control mechanism for one-to-many communication with provable fairness properties. The optimization-based approach attempts to find an allocation of rates that maximizes the aggregate utility o...

Video communication with Quality of Service (QoS) is an important and challenging task. To have QoS provision or guarantee at application level in the current best-effort Internet, congestion control and error control are two effective approaches. In this paper, we propose a new network-adaptive congestion control scheme for scalable video streaming in conjunction with Unequal Loss Protection (...

Despite the growing rates of vehicles on the roads and transported goods, transportation and traffic should become safer, cleaner and more efficient. Thus to ensure reliable and safe communication architecture within VANET, we propose in this context a cooperative and fully distributed congestion control approach, dedicated to operate within vehicular networks, integrated within the 802.11p und...
