Efficient Radio Resource Management for Future Mobile Wireless Networks Using Scalable Resource Allocation Algorithm

摘要

The success of the deployment of mobile wireless networks will be significantly influenced by the introduction of efficient and variable Quality of Service (QoS) management and supporting mechanisms. This includes QoS management in the areas of call admission control and radio resource allocation techniques for multiple-services. In the future wireless mobile networks, it is anticipated that a wide variety of data applications, ranging from WWW browsing to Email, and real time service like packetized voice and videoconference will be supported with varying levels of QoS. Therefore, there is an urgent need to improve the capacity of data services whilst not compromising the voice Grade of Service (GoS) at all times.rnThis paper introduces the concept of Scalable Resource Allocation (ScRA) technique, which aims to improve the radio resource efficiency for heterogeneous traffic without violating the voice service GoS. The efficiency of ScRA technique is investigated against the conventional radio resource allocation technique, namely Static Resource Allocation (StRA). The efficiency of our ScRA technique is investigated in diverse and dynamic traffic scenarios with different types of service combinations. Our analysis of the simulation results indeed indicate that our ScRA technique can yield lesser time delay in the data transaction, achieving greater spectral efficiency, higher throughput and not compromising the voice services GoS at all times.
