A decentralised, measurement-based admission control mechanism for self-aware networks

Abstract

This paper presents a decentralised Admission Control (AC) algorithm, based on the centralised proposed in [1{4]. Our algorithm is a multiple criteria AC algorithm, where each user can specify the QoS metrics that interest him/her, and decides whether a new call should be allowed to enter the network based on measurements of the QoS metrics on each link of the network before and after the transmission of probe packets. Our algorithm will be briefly described and we will present experimental results, conducted in a large laboratory test-bed, under highly congested circumstances. © 2011 Springer Science+Business Media B.V.
