Analysis of Reconfigurability, Control and Resource Management in Heterogeneous Wireless Networks

摘要

Modern communications networks integrate different access technologies that require interoperability for seamless and user-transparent transfer of multimedia-reach content. Latest standardization activities in this area pinpoint the IEEE 802.21 standard as an enabler of media independent handovers in various scenarios. Additionally, the implementation of the heterogeneous network paradigm yields optimized and efficient resource management techniques emphasizing the need for reconfiguration and interoperability capabilities within future wireless networks. This paper analyzes a combination of reconfigurability, interoperability and resource management aspects in heterogeneous wireless networks based on the IEEE 802.21 standard. It introduces a novel platform for wireless heterogeneous communication systems and a prototype of a reconfigurable mobile terminal that rely on the IEEE 802.21 standard. The introduced platforms are extensively validated through simulations and laboratory experiments showcasing that the IEEE 802.21-backed interoperability is able to support uninterrupted content delivery across multiple communication technologies with high performance.
