Efficient Queue based Channel Allocation Model for User Impatience in Enterprise Networks

Abstract

The vast usage of next generation smart networks makes the researchers to concentrate more on the efficient spectrum utilization by availing channels to the secondary users without interrupting the existing primary user’s data transmission. The handoff mechanism for both Secondary users (SU’s) and Primary users (PU’s) including new SU’s arrival in a zonal coverage region was considered. A queuing model that uses two buffers are chosen namely handoff buffer and new SU’s buffer have been proposed for efficient channel allocation in the 5G networks. Many next generation networks like 5G, TVWS networks, CRNs, IoT, IIoT, LTE-U etc. uses queuing mechanism of channel allocation to the secondary users as the future networks are migrating to the utilization of licensed band due to channel starvage. In this paper a new SU’s buffer to accommodate starving SU’s for some time has been proposed and analyzed using Markov-chain analysis. In this paper analysis work was carried out by using Markov-Chain model for different transition states from a generic state, to analyze the dropping and blocking probabilities of SU’s in competitive scenario.
