| 英文摘要 | Call admission control (cac) is crucial for assuring the quality of service (qos) of communication in wireless cellular networks. in this paper, we propose a model, called guard channel prediction model (gcpm), for efficient call admission control satisfying the qos requirements. a predictive value of the appropriate number of guard channels can be calculated based on this model by using statistical properties of new and handoff call arrival rates and mean call residency time, as well as the total capacity of a specific cell. simulation studies are carried out to evaluate the performance in comparison with an existing adaptive algorithm under variable traffic loads and mobility patterns. simulation results show that our proposed gcpm, using the static and fractional guard channel policy to process both types of incoming calls based on the predictive values, has gained better qos with less blocking probabilities of both types of calls and meanwhile, larger network utilizations. |
