TV White Space (TVWS) is becoming a useful communication medium through cognitive radio techniques. IEEE 802.22 Wireless Regional Area Network (WRAN) has been adopted as a standard in this regard. WRAN has a coverage radius of up to 30km. Due to large cells and opportunistic spectrum utilization, the self-coexistence situation, where multiple WRAN Base Stations (BSs) share the same spectrum band in the same region, is expected to be common. This paper explores the use of relay-based WRANs to improve the transmission performance under the self-coexistence situation; this performance improvement has not been reported to the best of our knowledge. In particular, we investigate the delay performance of multi-hop WRANs under the self-coexistence situation using simulations, and compare the performance to the case of single-hop WRANs without relay. We also evaluate the delay performance for hybrid scenarios where some of the Consumer Premise Equipments (CPEs) use relay while others communicate directly to BSs. Numerical results indicate that using relay transmissions for CPEs in the overlap area of selfcoexisting WRANs can help decrease the average packet delay when the transmission resources become scarce.

“…To increase the spectrum efficiency and network capacity significantly when there is lot of intra-cellular traffic, P2PWRAN has been proposed [4]. P2PWRAN is similar to Device-to-Device communication in heterogeneous networks [5], and can be considered as a special case with centralized spectrum control, multiple operating channels and power control.…”

“…P2PWRAN is based on IEEE 802.22 standard with minimal changes to enable P2P communications. In our earlier work we have not addressed the details of how P2PWRAN is enabled [4]. In this paper, we look into the details in the OFDMA system and resource allocation.…”

IEEE 802.22 is the first standard to uitilize cognitive radio technology for wireless regional area networks (WRANs). It has adopted a cellular topology containing one base station (BS) and multiple customer premises equipments (CPEs) in a cell. It covers a very large area with radius ranging up to 100 km. Orthogonal frequency-division multiple access (OFDMA) system is employed and it is further slotted in time-domain. In one slot only one CPE can be allocated, and every intra-cell packet needs to be routed through the BS. This point-to-multi-point structure significantly limits the network capacity in the case of CPE-CPE communication, which is predicted to happen, and even the use of OFDMA does not help much. Therefore, peer-topeer WRAN (P2PWRAN) has been proposed to support direct intra-cell communication in order to extend the network capacity. In this paper, the IEEE 802.22 OFDMA system is adapted to P2PWRAN to support direct CPE-CPE communications. The downstream burst allocation in P2PWRAN is similar to the OFDMA system of IEEE 802.16, which has been widely studied in the literature. Therefore, in this paper we look at the unexplored upstream burst allocation where slots can be reused among CPEs and the BS with power control mechanisms. We propose a burst allocation algorithm that maximizes the network capacity greedily. The algorithm is examined under various conditions such as, number of CPEs, size of requests, length of US subframes and type of requests (CPE-BS or CPE-BS). We also show that our algorithm performs better than the existing solutions.Index Terms-IEEE 802.22, WRAN, OFDMA, cognitive radio, channel allocation, burst allocation.Globecom 2013 -Cognitive Radio and Networks Symposium 978-1-4799-1353-4/13/$31.00 ©2013 IEEE

“…In a typical cellular network like WRAN, user terminals have to communicate via the base station and they cannot communicate with each other directly. To address this drawback and to take advantage of both centralized control and the sharing of spectrum among user terminals, Peer to Peer WRAN (P2PWRAN), which requires the information regarding potential interference among flows, i.e., interference map, has been proposed in [93]. The accuracy of this interference map affects the channel allocation as well as the network performance.…”

Abstract-Compressive Sensing (CS) has received much attention in several fields such as digital image processing, wireless channel estimation, radar imaging, and Cognitive Radio (CR) communications. Out of these areas, this survey paper focuses on the application of CS in CR communications. Due to the underutilization of the allocated radio spectrum, spectrum occupancy is usually sparse in different domains such as time, frequency and space. Such a sparse nature of the spectrum occupancy has inspired the application of CS in CR communications. In this regard, several researchers have already applied the CS theory in various settings considering the sparsity in different domains. In this direction, this survey paper provides a detailed review of the state of the art related to the application of CS in CR communications. Starting with the basic principles and the main features of CS, it provides a classification of the main usage areas based on the radio parameter to be acquired by a wideband CR. Subsequently, we review the existing CSrelated works applied to different categories such as wideband sensing, signal parameter estimation and Radio Environment Map (REM) construction, highlighting the main benefits and the related issues. Furthermore, we present a generalized framework for constructing the REM in compressive settings. Finally, we conclude this survey paper with some suggested open research challenges and future directions.
