There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The rapid growth of wireless communications either from the perspective of the number of subscribers or multimedia services is driving the evolution from the second generation towards next-generation wireless networks. The major issue in such networks is to accommodate demanding heterogeneous services with a desired quality of service while keeping the best possible
mobility performance.
This work aims to extend the performance analysis of third and fourth generation networks through a new modeling approach that describes the combined effect of the mobility of subscribers and the teletraffic they generate.
The transient and limit analysis of the number of mobiles per call state in a cell as well as the handoff processes from the cell are investigated. The new and handoff call blocking probability for network planning are derived, and the distribution of the required capacity in a short time interval for network control is obtained. Simulations are carried out to validate the analytical results.
