Upper Bounds of Different Traffic Types in IEEE 802.22 Based CRNs

Nikita Bhagat, Dr. Jyoteesh Malhotra

Abstract


Data communication networks are a vital component of any modern society. They are used extensively in numerous applications, including financial transactions, social interactions, education, national security, and commerce. In particular, both wired and wireless devices are capable of performing a plethora of advanced functions that support a range of services, such as voice telephony, web browsing, streaming multimedia, and data transfer. With the rapid evolution of microelectronics, wireless transceivers are becoming more versatile, powerful, and portable. In the wireless technology, the major issue is the issue of spectrum utilization. The utilization of spectrum has increased to its maximum level. To tackle this issue the technology named cognitive radio was introduced to the rescue. The Cognitive radio is an emerging technology that facilitates dynamic spectrum access in wireless networks. The cognitive radio is capable of expediently using the obtainable portions of a licensed spectrum to improve the application performance for unlicensed users. The opportunistic access of the accessible channels in the wireless environment requires dynamic channel assignment to efficiently utilize the available resources while minimizing the interference in the network. In this paper, we are focusing the different traffic types such video and voice. In the voice, we have different codec and in the video application, we have different model types from which we need to choose the best for the optimum results.
