QoS Provisioning for Wireless Cellular Network
Abu Najib Kaifi · 2013
The 3G wireless cellular networks provide the multimedia communication that can be enjoyed by the user any time anywhere..Call Admission control in wireless cellular network is to guarantee Quality of Service(QoS) this is a challenging issue for the wireless network due the mobility of user. The design of call admission control algorithms for mobile cellular networks is especially challenging given the limited and highly variable resources, and the mobility of users encountered in such networks This paper proposed a CAC algorithm for three types of call classes voice, data and video. In our proposed algorithm we have divided the call of a cell into newly generated call and handoff call. Handoff call is given more priority than newly generated call in the network .we calculate the new-call and handoff-call blocking probabilities. The analytical results are verified through simulation and found to be absolutely satisfactory .
