A novel DCA scheme for resource sharing in cellular environments with heterogeneous traffic

Abstract

In cellular networks it is crucial to be able to use the available radio spectrum as efficiently as possible while providing a certain level of Quality of Service (QoS) for users. Emergence of miscellaneous services has dramatically increased the complexity of this problem by creating a heterogeneous traffic environment. In this paper an efficient resource allocation scheme has been proposed for cellular networks with multimedia traffic, which combines classical resource borrowing concept with a novel inter-cell resource sharing scheme between different classes of traffic. By assuming the heterogeneous offered traffic to be a combination of audio and video traffic types, it will be shown that the proposed resource allocation scheme is capable of significantly improving audio teletraffic performance of the system without imposing additional expense upon video QoS performance. © IFIP International Federation for Information Processing 2003.
