Abstract
This paper proposes a wireless communication system comprising a DSM (Dynamic Spectrum Management) Engine and DSM clients that can dynamically and opportunistically use and aggregate TVWS spectrum when deployed in a local area such as a home or a small office. Operation in TVWS spectrum requires technology that can address the sparse and non-contiguous nature of TVWS spectrum as well as the availability and quality of the TVWS channels due to the presence of primary and secondary users. A new wireless communication architecture is proposed where the focal point is an aggregated robust wireless link (DSM Link) between the DSM engine and the DSM clients. Simulation results show significant gains in performance in terms of satisfied users, robustness and latency when compared with a conventional 802.11 system.
