Despite the tremendous bandwidth increase in 3 generation (3G) Broadband Wireless Networks (BWNs) such as Universal Mobile Telecommunication System (UMTS), maintaining the mobile users’ Quality of Service (QoS) requirements while maximizing the network operators’ revenues is still a challenging issue. Moreover, spatial distribution of network traffic has a negative impact on the overall network...

rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. most commonly used algorithm in end hosts is tcp. this is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by tcp affect other sessions...

An explicit rate indication scheme for congestion avoidance in computer and telecommunication networks is proposed. The sources monitor their load and provide the information periodically to the switches. The switches, in turn, compute the load level and ask the sources to adjust their rates up or down. The scheme achieves high link utilization, fair allocation of rates among contending sources...

Congestion has posed a big problem in (ATM) network. Every network user encounters congestion issues. In terms of network, congestion is unpredictable; it can be caused by traffic or too many data that cluster together in the system. In telecommunication, congestion occurs when more users access the network; during the peak period when the control channel is congested as such call cannot be est...

The successful functioning of telecommunication networks largely depends on the effectiveness algorithms for detection and protection against overloads. article describes main differences that arise when forecasting, monitoring managing congestion at node level channel level. An algorithm detecting by estimating entropy time distributions traffic parameters is proposed. measures data sets vario...

During the last few decades, mobile communication has developed rapidly. The increasing dependency of people on telecommunication resources is pushing even more current technological developments in the mobile world. In Real-time multimedia applications, such as Live TV or live movie, video conferencing, VoIP, on-line gaming etc. are exciting applications to the success of 4G.In today’s Interne...

The intelligent transportation systems (ITS) framework from European Telecommunication Standards Institute (ETSI) imposes requirements on the exchange of periodic safety messages between components of ITS such as vehicles. In particular, it requires ETSI standardized Decentralized Congestion Control (DCC) algorithm to regulate the beaconing activity of vehicles based on wireless channel utiliza...

Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...

0163-6804/97/$10.00 © 1997 IEEE he need for telecommunication networks capable of providing diverse and emerging communication services such as data, voice, and video, motivated the standardization of broadband networks. The need for a flexible design that can accommodate future services and advances in technology led International Consultative Committee for Telephone and Telegraph (CCITT) to a...
