Survey on call admission control protocols in cellular networks

Abstract

The use of cellular networks over a period of time has resulted in the establishment of effective mobile networks for cellular data transmission. The main requirement for data transmission is the availability of radio frequencies but with the increasing applications there is a scarcity of radio frequencies. One way to overcome this is by employing the concept of call admission control so as to enforce proper resource utilization among all the participating nodes. But the main concern here is with respect to the quality of service in terms of several metrics based on the underlying applications. The survey conducted here provides with a detailed insight into the problems existing with respect to data transmission with QoS requirements. Several existing protocols have been analyzed and along with the current research issues.
