Call admission control is the problem of deciding for a given set of connection requests which of them to accept and which to reject, with the goal of maximizing the profit obtained from the accepted requests. The problem is considered in a scenario with advance reservations where users can specify several alternatives for when and how they want their connections to be established. Two variants...

This paper addresses the problem of admission control for IP networks with QoS support. Several admission control architectures and algorithms are presented and compared. Special attention is given to the probing algorithm. The stealing problem associated with this mechanism is studied through simulation.

Provision of Quality-of-Service (QoS) guarantees is an important and challenging problem in the design of integrated-services packet networks. Call admission control is an integral part of the challenge and is closely related to other aspects of networks such as service models, scheduling disciplines, traffic characterization and QoS specification. In this paper we provide a theoretical framewo...

This report introduces two main categories of call admission control algorithms in integrated-services network, namely eeective bandwidth (EBW) approach and measurement-based admission control (MBAC). EBW is a dominant scheme for network resource management and admission control in broadband network environment. It determines the accommodation of new connection request by comparing the availabl...

In the present paper, we develop an adaptive algorithm for call admission control in wireless networks. The algorithm is built upon the concept of guard channels and it uses an adaptation algorithm to search automatically the optimal number of guard channels to be reserved at each base station. The quality of service parameters used in our study are the new call blocking probability and the han...

The major bene t of ATM is its exibility in multiplexing communication services that have very di erent tra c characteristics. A call admission control scheme presented in this paper makes use of \Intelligent" Neural Networks. The main bene t of this approach is its simplicity and adaptability. 1

This paper proposes a novel call admission control (CAC) scheme for wireless mobile networks. Our proposal avoids per-user reservation signaling overhead and takes into account the expected bandwidth to be used by calls handed off from neighboring cells based only on local information stored into the current cell where user is seeking admission. To this end, we propose the use of two time serie...

Generalized Processor Sharing(GPS) is an idealized fluid discipline with a number of desirable properties. Its packetized version PGPS is considered to be a good choice as a packet scheduling discipline to guarantee Quality-of-Service in IP and ATM networks. The existing Connection Admission Control(CAC) frameworks for GPS result in a conservative resource allocation. We propose an Optimal CAC ...

Among various radio sources which control different dependencies/functions, in this article, we will talk about the Call Admission Control (CAC), and we are supposed to confine our concentration on W-CDMA which is based on high raised platforms, since during the recent years remarkable amount of attention has been focused on platforms located in stratosphere layer [1]. Firstly, we study the cap...
