“…The rate of convergence to a fair operating point is also affected by α. As shown in [14], [15], the smaller the value of α, the faster the convergence. Parameter α can also affect the network utilization in the bottleneck area.…”

“…5, there are three 9-node chains and there is a one-way CBR/UDP flow on each chain. We set α to 0.6 in this simulation according to (14) for a reasonable operation point. The information about each connection along with the starting/ending time is listed in Table 1 We first set these three chains close to each other so that a node in a chain and its competitors in the other two chains can see the same channel utilization.…”

Flow control in mobile ad hoc networks (MANETs) encounters more challenges than flow control in conventional wired networks, such as channel bandwidth variation, medium contention, and frequent re-routing. Without proper flow control, serious network performance degradation in MANETs has been reported in recent studies. In this paper, we introduce a distributed bottleneck flow control technique in MANETs. The proposed scheme uses a distributed flow control mechanism that has been used in both bottleneck flow control and bandwidth balancing in Distributed-Queue-Dual-Bus (DQDB) in wired networks. It extends bandwidth balancing to operate in a mobile wireless environment. Extensive simulations demonstrate that our flow control scheme is effective and can provide max-min fairness as well as improve Quality of Service (QoS) for flows in MANETs.

“…The mechanism forces each node to pass a fraction of l/(Mx,km + I} accessible slots untouched and, therefore, node n in part m of subnetwork k uses MXkm/(MXkm + I} of the available throughput on bus X as a maximum (Hahne et al, 1992). So' ,…”

This paper investigates the throughput performance of a system made up of a number of IEEE 802.6 subnetworks interconnected among each other, in overload conditions. The approach adopted in mode\ling the internet system enable us to leave any technical implementation issue regarding the Interconnection Unit (IU) out of consideration. In this respect, the IU is viewed as a black box characterized by some basic functionalities which may be met by a wide range of interface protocols. An analytical methodology is presented which allows us to solve some relevant design problems. In particular, we show that by non-linear programming algorithms it is possible to determine the best location and protocol of the IU interfaces on condition that the maximum system throughput is achieved. Finally, we provide some numerical examples concerning two identical DQDB subnetworks interconnected by IUs, located at either the middle or the headend of the subnetworks.

A metropolitan area network (MAN) is a shared network that covers the distances in most cities. The applications of MANs and the techniques that are used for communications is rapidly changing. MANs were originally used to interconnect the users in a single organization, and several specialized networks were developed. However, the Internet has increased the demand for high‐speed communications to individual consumers. In consumer applications, cost is particularly important. The networks use existing infrastructure or infrastructure that can be deployed with minimal investment and use access devices that are popular in other applications and therefore cost less than new devices. The first generation of MANs used protocols and network topologies that are similar to local area networks but are specifically designed to span the greater distances and operate at the higher transmission rates that occur in a MAN. We describe three of these protocols: the American National Standards Institute (ANSI) X3T9 standard, fiber distributed data interface, (FDDI), the IEEE 802.6 standard, dual bus distributed queue protocol, (DQDB), and an experimental network, the Manhattan Street Network, (MSN). Currently, the most widely used MANs use the existing cable TV (CATV) network and easily deployed wireless networks. The CATV standards are not keeping pace with the applications. We describe the common characteristics of the applications and describe in detail an application that is based on Ethernet technology and that can be extended to carry packet voice communications. The IEEE 802.11 standard, wireless fidelity (WiFi), is the most widely used wireless access technology. This standard is described in detail, along with a competing access technique, Bluetooth, and the IEEE 802.16 standard that can be used to extend the range of wireless access techniques to the metropolitan area. In the conclusion we predict future changes. These changes are fueled by the need for improved reliability, the emergence of IP‐voice, the increased use of wireless technologies, the overuse of the cellular bands, the eventual deployment of fiber to the home, and a resurgence of ATM‐like, cell‐based transmission.
