On Performance Analysis of IEEE 802.22 PHY for Cognitive Radio based Smart Grid Communications

Abstract

Smart Grid (SG) communication architecture involves multiple network layers starting from control center to consumer areas, in a top-bottom hierarchy. At each network layer, several SG applications need to be supported with diverse Quality-of-Service (QoS) requirements. Cognitive Radio (CR) which provides efficient spectrum utilization through opportunistic spectrum access is a promising solution to meet these versatile requirements. The IEEE 802.22 Wireless Regional Area Network (WRAN) is aimed at the use of CR by allowing the unused spectrum of television broadcast service for providing broadband access to remote areas. This standard provide a variety of the modes of operation to support various QoS demands. In this paper, we provide the performance comparison of various modes of IEEE 802.22 standard when applied to different SG applications to show its compliance with the SG communication infrastructure. The frame sizes and other parameters are taken as per the SG application requirements. Furthermore, various bounds on channel quality are also provided to support the reliability requirements of different SG applications using this standard.
