An Efficient Channel Allocation Strategy in Wireless Multmedia Networks
무선 멀티미디어 망에서의 효율적인 채널 할당 방식
Abstract
Wireless multimedia networks require channel allocation strategies for various multimedia traffic since the mobility of users needs to be considered in addition to diversity of QoS requirements of multimedia traffic. In this paper, we propose an Efficient Channel Allocation strategy, based on prioritization of handoff calls used in Guard channel method. Gurad channels can be shared between non real time calls and real time handoff calls. To decrease the probability of handoff failure, when resources become scarce, the Call Admission Control can take some resources away from the active calls. It is shown through extensive simulations that the proposed strategy provides higher channel utilization and lower probability of handoff failure than existing strategies.
