Abstract

The paper examines the performance of a new dynamic resource allocation (DRA) strategy for a 3G hierarchical cellular structure (HCS). With rising demands on wireless communication systems there is a need to improve the resource utilisation of mobile networks. This can be achieved with the implementation of HCS along with a suitable self-adaptive DRA strategy. The main focus of attention is to evaluate the ability of the new DRA strategy to deal with multimedia traffic. Simulation results confirm that the modified DDRA (distributed DRA) performs adequately in the HCS under multimedia traffic conditions.
