Developing and establishing standards is crucial to a modern world community aspiring to take advantage of technological advancements. In particular, communications and networking standards enable equipment interoperability, reduce the cost, and thereby ...

In late July, shortly before this column was written, the WCET Core Team held a half-day meeting to review the program status, resolve questions, and plan activities for the remainder of the year. A short review of some of the issues addressed during ...

The article following, written by one of the lead engineers in the project, describes the development of AMPS, the first cellular telephone system in the United States. As noted, the project ran for over 12 years and required the services of a "vast ...

The following three books are reviewed in this issue: Network Modeling and Simulation: A Practical Perspective (Mohsen Guizani, Ammar Rayes, Bilal Khan, Ala Al-Fuqaha, John Wiley & Sons, Ltd., 2010); MIS 2010; Instructor's Edition (Hossein Bidgoli, ...

Fiber optic cables form the basis of almost all terrestrial communications networks today. Even mobile phone calls and television signals are carried over fiber optic cables as they traverse the path they must travel from source to destination. ...

This article presents OTN evolution from an operator's point of view, including the history of the transport network, the role of the OTN, and the motivations and requirements for OTN evolution. First, a history of transport networks and the role of the ...

The ITU-T G.709 standard is perhaps the most underrated and yet widely used of all telecommunication standards, especially pertaining to the transport layer. In this article we focus on OTN as a delivery platform for emerging services. We will ...

This article describes the timing aspects of optical transport networks as defined by ITU-T SG15 Q13. It first presents the initial decisions that led to the specification of Recommendation G.8251 in 2001, which defined the OTN network limits and the ...

Forward error correction codes for 100 Gb/s optical transmission are currently receiving much attention from transport network operators and technology providers. We discuss the performance of hard decision decoding using product type codes that cover a ...

Conventional wireless networks have been designed from a centralized perspective and with a predefined infrastructure, such as cellular networks, but this rigid approach lacks flexibility and adaptability, which are advantages of nextgeneration ...

This article details the current work status of the ETSI Reconfigurable Radio Systems Technical Committee, positions the ETSI work with respect to other standards efforts (IEEE 802, IEEE SCC41) as well as the European Regulatory Framework, and gives an ...

Channel management policy is one of the key functions of any cognitive radio system. The channel management decision in a cognitive radio system depends on various factors such as government regulations, limitations of transmission power between ...

This article reviews, discusses, and classifies the existing experimental platforms and testbeds for experimental evaluation of CR ad hoc networks. The article first describes the internal organization of typical existing software defined radio ...

Wireless communication technology is constantly advancing with the primary objective being to improve the quality of service for the end user. Cognitive radio is a technology capable of advancing wireless communications to the next generation of ...

Iris is a software architecture for building highly reconfigurable radio networks. It has formed the basis for a wide range of dynamic spectrum access and cognitive radio demonstration systems presented at a number of international conferences between ...

Small, portable computing devices now have connectivity based on both mobile phone standards and computer wireless standards. This provides opportunities to tailor new applications to the specific properties of these devices and those of the humans who ...

Personal computing devices, such as smart-phones and PDAs, are commonplace, bundle several wireless network interfaces, can support compute intensive tasks, and are equipped with powerful means to produce multimedia content. Thus, they provide the ...

Mobile phones or smartphones are rapidly becoming the central computer and communication device in people's lives. Application delivery channels such as the Apple AppStore are transforming mobile phones into App Phones, capable of downloading a myriad ...

The Shim6 architecture enables IPv6 multihoming without compromising the scalability of the global routing system by using provider aggregatable addresses. To do so, hosts use different addresses as locators for data packet transmission, but present the ...

Networking research often relies on synthetic traffic generation in its experimental activities; from generation of realistic workload to active measurements. Often researchers adopt software-based generators because of their flexibility. However, ...

The Internet Engineering Task Force has standardized a new network configuration management protocol called NETCONF, which provides mechanisms to install, manipulate, and delete the configuration of network devices. This article describes the NETCONF ...
