Return to Networks and Systems Issues There is a tremendous growth of broadband multimedia services in mobile cellular networks. Call admission control (CAC) is the most significant issue in quality of service (QoS) provisioning for these services. We propose an adaptive CAC, which upgrades the upper limit (UL) scheme and is verified through the simulation. The proposed algorithm allows each cell to accept a new call if the estimated average differential of each multiclass handoff failure probability is nonpositive. The generic form of the algorithm is independent of cellular network structure. ![]() DiSC'02 © 2003 Association for Computing Machinery |
