Performance of Cognitive Radio Spectrum Access With Intra-And Inter-Handoff
Opportunistic Spectrum Access (OSA) is a technology that allows unlicensed users to access spectrum holes and to provide so efficient use of radio resources. Most studies done on OSA focus on the situation when the unlicensed user performs the spectrum handoff only within a single cognitive radio network (so-called intra-handoff). In this paper, the authors consider the users (licensed or unlicensed) to be able to do inter-handoff among different cognitive radio cells as well. The cells provide priority to inter-handoff users. By considering multiple cells being in steady state and showing identical statistics, the arrival rates of inter handoff users are determined.
