Title: A Novel Approach to Reduce the Spectral Ping-Pong Effect for the Mobility Management Framework in a Cognitive Radio Cellular Network.
Authors: Vinay S. Prabhavalkar and Vijay R. Ghorpade
Abstract: Cognitive radio devices use the unutilized spectrum i.e. the unutilized frequency resource from the underlying technology in that region. When a primary user appears in a channel, the cognitive radio (CR) devices switch to a different channel which leads to spectral handoff. When this switching happens in a very quick succession, the CR device barely gets chance to carry out its work and is forced to account the spectral handoff's leading to the spectral ping-pong effect. In this paper, two load based algorithms are devised that consider the current load on the system to allocate the frequency resources to the CR devices. CR_resource_allocation algorithm allocates resources when a CR device enters the coverage area of a base station (BS), and CR_handoff algorithm allocates resources to the CR device when it undergoes a handoff process. Simulations show that, the proposed algorithms significantly reduce the number of handoff for the CR device thereby reducing the spectral ping-pong effect.
