Joint Integrated Spectrum Handoff Management and Routing in CR-MANETs: An Analytical Modeling

The focus of this paper is on the modeling of joint Integrated Spectrum Handoff MANagement (ISHMAN) and routing in cognitive radio mobile ad hoc networks (CR-MANETs). To model the ISHMAN, we must consider three key factors: (1) channel availability and spectrum usage behaviors of the primary users (PUs); (2) the movements and the motility of the secondary users (SUs); and (3) channel quality degradation. In this paper, we propose a new model for spectrum handoff in CR-MANETs considering the above mentioned factors characterizing the united ISHMAN and routing in these networks.
