Spectrum Allocation for Delay Sensitive ...

This paper, focused on delay-sensitive applications, considers the delay deadlines for delay-sensitive applications and proposes a dynamic spectrum allocation. In order to manage available distributed spectrum resources, cognitive user exchanges information through a virtual queue interface and uses the priority queuing to analyze different expectations of delay priority, and the corresponding DSL (dynamic strategy learning) algorithm, so that the delay-sensitive user can dynamically adapt to the channel options and achieve the purpose of minimizing packet loss rate.
