      abstract = {This Springer Brief investigates the voice and  elastic/interactive data service support over cognitive  radio networks (CRNs), in terms of their delay  requirements. The increased demand for wireless  communication conflicts with the scarcity of the radio  spectrum, but CRNS allow for more efficient use of the  networks. The authors review packet level delay  requirements of the voice service and session level delay  requirements of the elastic/interactive data services,  particularly constant-rate and on-off voice traffic  capacities in CRNs with centralized and distributed network  coordination. Some generic channel access schemes are  considered as the coordination mechanism, and call  admission control algorithms are developed for  non-fully-connected CRNs. Other key topics include the  advantages of supporting voice traffic flows with different  delay requirements, the mean response time of the elastic  data traffic over a centralized CRN, and efects of the  traffic load at the base station and file length (service  time requirement) distribution on the mean response time.  The brief is designed for professionals and researchers  working with wireless networks, cognitive radio, and  communications. It is also a helpful reference for  advanced-level students interested in efficient wireless  communications.},
