Unfairness of measurement-based admission controls in a heterogeneous environment

Admission controls are required to determine whether new connections should be admitted to networks. These controls ensure the quality of service (QoS) for data transmission. This paper introduces three measurement-based admission control algorithms called Measured Sum, Hoeffding bound and Adaptive Weight Factor. The unfairness of these algorithms in a heterogeneous environment is investigated. Simulation results indicate the fairness of the Measured Sum exceeds that of the other methods. Connections with large peak rates or traveling many hops are difficulty admitted.
