IPTV delivery using cognitive radio principles

Abstract

Cognitive radio principles enable the ability to utilise radio resources in an opportunistic manner without the need and limitations associated with centralised or fixed allocation of resources. However, in order for these approaches to be exploited requires in-depth understanding of the radio channel and traffic models in order that the most suitable resource sharing strategies are employed. This paper examines the exploitation of cognitive radio principles for delivery of IPTV content on demand within unmanaged wireless environments. This is particularly applicable within composite home wireless networks, but increasingly in other scenarios in which radio resources need to be shared in an autonomous and dynamic manner. The paper explores channel models, traffic models and presents some results from experimental implementation to learn the best channel selection strategies.
