This paper addresses the design and analysis of an end-to-end rate-based feedback flow control algorithm motivated by the available bit rate (ABR) service in wide-area asynchronous transfer mode (ATM) networks. Recognizing that the explicit feedback rate at time will not affect the ABR buffer until time + for some 0, our approach is to first predict the ABR(More)
For Internet Telephony to be a viable alternative to the Public Switch Telephone Network (PSTN), efficient and high quality communications are required. This paper proposes an optimization algorithm that selects parameters like coding scheme, packet loss bound, and maximum link utilization level in a Voice over IP (VoIP) network. The goal is to deliver(More)
Advances in technology have greatly increased the demand for a single integrated service network that can provide multiple service classes for different user requirements. For such a multiple-service network, congestion control is one of the key issues to be addressed. However, without an appropriate mechanism to encourage end users to use the network(More)
The Rapidly Deployable Radio Network (RDRN) is an architecture and experimental system to develop and evaluate hardware and software components suitable for implementing mobile, rapidly deployable, and adaptive wireless communications systems. The driving application for the RDRN is the need to quickly establish a communications infrastructure following a(More)
