Abstract :
This paper proposes a utility-based connection admission control (CAC) scheme for IEEE 802.16e broadband wireless access (BWA) networks. We develop specific utility functions for real-time and non-real-time services coupled with a handover process. By means of these functions we present a novel utility-based CAC algorithm which determines a connection that conducts to the greatest utility in each time of admission decisions, so as to maximize the total system utility. Simulation results demonstrate the effectiveness of the proposed CAC scheme.
