Abstract

Connection Admission Control (CAC) is the process that decides which connection requests are admitted to the system and allocated resources. CAC in wireless networks differs from wireline networks due to mobility and scarcity of wireless resources, and the physical properties of the radio channels. In this chapter, the basic issues in CAC for wireless systems are discussed in the context of resource management and trade-off between blocking and dropping rates. Though it is not among the topics of this chapter, quality of service (QoS) provisioning is also briefly mentioned due to its relationship with CAC. Following the discussion of the common and different points of CAC in both wireline and wireless systems, admission control in next-generation wireless systems is explained.
