The Dynamic Spectrum Access Networks Standards Committee (DySPAN-SC), formerly Standards Coordinating Committee 41 (SCC41), and even earlier the IEEE P1900 Standards Committee, is sponsored by the Institute of Electrical and Electronics Engineers (IEEE). The group develops standards for radio and spectrum management. [1] Its working groups and resulting standards, numbered in the 1900 range, are sometimes referred to as IEEE 1900.X.
The IEEE P1900 Standards Committee was established in March 2005 jointly by the IEEE Communications Society (ComSoc) and the IEEE Electromagnetic Compatibility Society (EMC). The effort developed supporting standards for radio and dynamic spectrum management. [1]
On March 22, 2007, the IEEE Standards Board approved its reorganization as Standards Coordinating Committee 41 (SCC41), Dynamic Spectrum Access Networks (DySPAN). The IEEE ComSoc and EMC sponsored this effort, as they did for IEEE 1900. The IEEE 1900 Committee ceased to exist at the inaugural meeting of SCC41 in April 2007. The work of the IEEE 1900.x Working Groups continued under SCC41. SCC41 voted to be directly answerable to ComSoc in December 2010, and was renamed as IEEE DySPAN-SC. At its December 2010 Meeting, the IEEE Standards Association Standards Board (SASB) approved the transfer of projects to the Communications Society Standards Board. [1]
DySPAN-SC focuses on Dynamic Spectrum Access and associated technologies. Due to the strong inter-relationships between such topics, it also touches on other areas such as Cognitive Radio. [2]
IEEE DySPAN-SC currently oversees the following standards development working groups: [1]
Proposed standards have "P" prepended to the name until they are ratified. The first to be published was 1900.2 in July 2008. [3] Next was 1900.1 on September 26, 2008. [4] Then 1900.4 was published on February 27, 2009. [5] Work then began on amendment P1900.4.1a for dynamic spectrum access networks in white space frequency bands, and P1900.4.1 for interoperability between components of the IEEE 1900.4 system. [6] The 1900.6 standard was published on April 22, 2011, and work began on an amendment 1900.6a. [7]
The IEEE 1900.4 Working Group is on "Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks" [8] It is a working group under the IEEE SCC41.
IEEE 1900.4 was published on February 27, 2009.
There are two projects for the 1900.4 Working Group starting April 2009:
Use cases (cases in which the protocols described by this standard will be used) include: [9]
The protocol was first popularized by various articles, including one on Monday, March 23, 2009. [10]
IEEE 802.15 is a working group of the Institute of Electrical and Electronics Engineers (IEEE) IEEE 802 standards committee which specifies Wireless Specialty Networks (WSN) standards. The working group was formerly known as Working Group for Wireless Personal Area Networks.
Beam tilt is used in radio to aim the main lobe of the vertical plane radiation pattern of an antenna below the horizontal plane.
A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network.
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location. This process is a form of dynamic spectrum management.
IEEE 802.22, is a standard for wireless regional area network (WRAN) using white spaces in the television (TV) frequency spectrum. The development of the IEEE 802.22 WRAN standard is aimed at using cognitive radio (CR) techniques to allow sharing of geographically unused spectrum allocated to the television broadcast service, on a non-interfering basis, to bring broadband access to hard-to-reach, low population density areas, typical of rural environments, and is therefore timely and has the potential for a wide applicability worldwide. It is the first worldwide effort to define a standardized air interface based on CR techniques for the opportunistic use of TV bands on a non-interfering basis.
In computer networking, a heterogeneous network is a network connecting computers and other devices where the operating systems and protocols have significant differences. For example, local area networks (LANs) that connect Windows, Linux and Macintosh computers are heterogeneous.
Sensor web is a type of sensor network that heavily utilizes the World Wide Web and is especially suited for environmental monitoring. OGC's Sensor Web Enablement (SWE) framework defines a suite of web service interfaces and communication protocols abstracting from the heterogeneity of sensor (network) communication.
Reconfigurability denotes the Reconfigurable Computing capability of a system, so that its behavior can be changed by reconfiguration, i. e. by loading different configware code. This static reconfigurability distinguishes between reconfiguration time and run time. Dynamic reconfigurability denotes the capability of a dynamically reconfigurable system that can dynamically change its behavior during run time, usually in response to dynamic changes in its environment.
IEEE 802.11h-2003, or simply 802.11h, refers to a 2003 amendment added to the IEEE 802.11 standard for Spectrum and Transmit Power Management Extensions. It addresses problems like interference with satellites and radar using the same 5 GHz frequency band. It was originally designed to address European regulations but is now applicable in many other countries. The standard provides Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC) to the 802.11a PHY. It has since been integrated into the full IEEE 802.11-2007 standard.
The neXt Generation program or XG is a technology development project sponsored by DARPA's Strategic Technology Office, with the goals to "develop both the enabling technologies and system concepts to dynamically redistribute allocated spectrum along with novel waveforms in order to provide dramatic improvements in assured military communications in support of a full range of worldwide deployments." It is financed by the United States government within the aim of developing a de facto standard for cognitive radio and dynamic spectrum regulation.
A wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes. The determination of which nodes forward data is made dynamically on the basis of network connectivity and the routing algorithm in use.
Dynamic spectrum management (DSM), also referred to as dynamic spectrum access (DSA), is a set of techniques based on theoretical concepts in network information theory and game theory that is being researched and developed to improve the performance of a communication network as a whole. The concept of DSM also draws principles from the fields of cross-layer optimization, artificial intelligence, machine learning etc. It has been recently made possible by the availability of software radio due to development of fast enough processors both at servers and at terminals. These are techniques for cooperative optimization. This can also be compared or related to optimization of one link in the network on the account of losing performance on many links negatively affected by this single optimization.
In radio resource management for wireless and cellular networks, channel allocation schemes allocate bandwidth and communication channels to base stations, access points and terminal equipment. The objective is to achieve maximum system spectral efficiency in bit/s/Hz/site by means of frequency reuse, but still assure a certain grade of service by avoiding co-channel interference and adjacent channel interference among nearby cells or networks that share the bandwidth.
Radio resource management (RRM) is the system level management of co-channel interference, radio resources, and other radio transmission characteristics in wireless communication systems, for example cellular networks, wireless local area networks, wireless sensor systems, and radio broadcasting networks. RRM involves strategies and algorithms for controlling parameters such as transmit power, user allocation, beamforming, data rates, handover criteria, modulation scheme, error coding scheme, etc. The objective is to utilize the limited radio-frequency spectrum resources and radio network infrastructure as efficiently as possible.
Cross-layer optimization is an escape from the pure waterfall-like concept of the OSI communications model with virtually strict boundaries between layers. The cross layer approach transports feedback dynamically via the layer boundaries to enable the compensation for overload, latency or other mismatch of requirements and resources by any control input to another layer, but that layer directly affected by the detected deficiency.
International Mobile Telecommunications-Advanced are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2008 for what is marketed as 4G mobile phone and Internet access service.
In communication networks, cognitive network (CN) is a new type of data network that makes use of cutting edge technology from several research areas to solve some problems current networks are faced with. Cognitive network is different from cognitive radio (CR) as it covers all the layers of the OSI model.
