Priority based Bandwidth Adaptation for Multi-class Traffic in Wireless Networks

The bandwidth adaptation is the technique that allows the flexibility in bandwidth allocation for a call. Using the bandwidth adaptation technique, the number of call admission in the system can be increased significantly. In this paper we propose a priority based bandwidth adaptation scheme that can release multi-level of bandwidth from the existing calls to accept call requests. The amount of released bandwidth is based on the number of existing bandwidth adaptive calls and the priority of requesting traffic call. This priority scheme does not reduce the bandwidth utilization. Moreover, the proposed bandwidth adaptation strategy provides significantly reduced call blocking probability for the higher priority traffic calls. The performance analyses show the improvement of the proposed scheme

Adaptive Resource Management for Multimedia Applications in Femtocellular and Macrocellular Networks

The increasing demands of various high data rate wireless applications have been seen in the recent years and it will continue in the future. To fulfill these demands, the limited existing wireless resources should be utilized properly or new wireless technology should be developed. Therefore, we propose some novel idea to manage the wireless resources and deployment of femtocellular network technology. The study was mainly divided into two parts: (a) femtocellular network deployment and resource allocation and (b) resource management for macrocellular networks. The femtocellular network deployment scenarios, integrated femtocell/macrocell network architectures, cost-effective frequency planning, and mobility management schemes are presented in first part. In the second part, we provide a CAC based on adaptive bandwidth allocation for the wireless network in. The proposed CAC relies on adaptive multi-level bandwidth-allocation scheme for non-real-time calls. We propose video service provisioning over wireless networks. We provide a QoS adaptive radio resource allocation as well as popularity based bandwidth allocation schemes for scalable videos over wireless cellular networks. All the proposed schemes are verified through several numerical and simulation results. The research results presented in this dissertation clearly imply the advantages of our proposed schemes.Comment: PhD Dessertatio
