Power Control Technique for Efficient Call Admission Control in Advanced Wireless Networks
In 4G networks, call admission control techniques have been proposed to provide Quality of Service (QoS) in a network by restricting the access to network resources. Power control is essential in call admission control in order to provide fair access to all users, improve battery lifetime and system performance. But the existing call admission control algorithms rarely consider the power controlling techniques in the handoff process for different traffic classes. In this paper, the authors propose to develop a power controlled call admission control scheme for handoff in the advanced wireless networks. The incoming call measures the initial interference on it and then the base station starts transmitting the packets to the new call.
