Abstract

WCDMA is a Wideband Code Division Multiple Access technique. Because of high data rate, it is mainly used in the 3 generation mobile networks. In Centralized Call Admission Control (CCAC) technique, when a new call arrives, the system checks whether the call should be admitted or not on the basis of Signal to Interference Ratio (SIR), transmission power, and the network load. If the call is accepted, it will increase some interference to the ongoing calls. This new interference would degrade the performance of ongoing calls, increase the outage rate, and ultimately affects the Quality of Service of the network. Hence, to reduce the interference while improving Quality of Service in the WCDMA network, an efficient Resource Allocation with Power Constraint (PC) in the network is required for achieving a higher throughput with appropriate handoff, improved battery life as well as network performance. This paper proposes an algorithm for Resource Allocation with Power Constraint (PC) for real time traffic in WCDMA Network. The simulation result shows that the proposed scheme can significantly reduce power consumption and increase throughput with less delay.
