Adaptive cognitive media delivery over composite wireless networks

Abstract

Over-the-top (OTT) content-on-demand (CoD) media delivery should ideally adapt to the available resources in an opportunistic manner. The dynamic nature of the Internet traffic and wireless local area networking technologies, which are typical within the home, must be considered in order to efficiently use resources without the need and limitations associated with centralised or fixed allocation of resources. It is also undesirable for devices to continuously monitor the available channels, especially if they are battery powered. Therefore, cooperation between devices and modelling of the dynamic adaptive traffic and terminal behaviour is necessary in order that the most suitable resource sharing strategies are employed. This article examines the exploitation of cognitive resource management for delivery of OTT CoD within unmanaged wireless environments. Channel and traffic models are derived based on the Markov modulated Poisson process and this knowledge is used to derive optimal resource sharing policies. Results from simulation and experimental implementation are presented.
