TECHNOLOGY ADVANCES FOR 3G AND BEYOND - HANDOVER MANAGEMENT FOR MOBILE NODES IN IPV6 NETWORKS - Mobile IPv6 is designed to manage mobile nodes' movements between wireless IPv6 networks. Nevertheless, the active communications of a mobile node are interrupted until the handover completes. Therefore, several extensions to Mobile IPv6 have been proposed to reduce the handover latency and the number of lost packets.
TECHNOLOGY ADVANCES FOR 3G AND BEYOND - QOS ISSUES IN THE CONVERGED 3G WIRELESS AND WIRED NETWORKS - Internet evolution delineated through the last years has urged the wireless network community to support the deployment of IP multimedia services with guaranteed quality of service in 3G wireless networks. This article copes with the interoperability between 3G wireless networks and wired next-generation IP networks, for the provision of services with an a priori known quality level over both environments.
TECHNOLOGY ADVANCES FOR 3G AND BEYOND - USING PATH PREDICTION TO IMPROVE TCP PERFORMANCE IN WIRELESS-MOBILE COMMUNICATIONS - After presenting previous efforts to ameliorate TCP performance in the considered environments, the authors propose a new mechanism for tackling the transmission slowdown problems caused by handovers. Their proposal is based on stochastic datagram relocation. Traffic destined to the mobile terminal is tunneled to and cached into adjacent cells according to the output of a path prediction algorithm.
TECHNOLOGY ADVANCES FOR 3G AND BEYOND - A SECURITY AND USABILITY PROPOSAL FOR MOBILE ELECTRONIC COMMERCE - The possibility of making the Internet accessible via mobile telephones has generated an important opportunity for electronic commerce. WAP was intended to become a general standard for business. Nevertheless, some deficiencies hinder its mass acceptance in e-commerce applications.
IN-HOME NETWORKING - HOME NETWORKING WITH IEEE 802.15.4: A DEVELOPING STANDARD FOR LOW-RATE WIRELESS PERSONAL AREA NETWORKS - The authors present the IEEE 802.15.4 draft standard and its home networking applications. The main features of the standard are network flexibility, low cost, and low power consumption; the standard is suitable for many applications in the home requiring low-data-rate communications in an ad hoc self-organizing network.
IN-HOME NETWORKING - DIGITAL DEVICE MANUALS FOR THE MANAGEMENT OF CONNECTEDSPACES - An increasing number of devices that can be monitored and controlled via the Internet have begun to appear in the commercial domain. When many such devices come together we say they form a ConnectedSpace. Many nonfunctional behavioral constraints may be imposed on a ConnectedSpace. Digital Device Manuals are envisioned to capture the generic information required by the different approaches to monitor and enforce the constraints.
IN-HOME NETWORKING - DEVICE AND SERVICE DISCOVERY IN HOME NETWORKS WITH OSGI - In this article we present an overview of the Open Services Gateway Initiative (OSGiTM) technology and its associated mechanisms for accessing devices. A technical description of work currently underway to map various industry device and service discovery protocols to OSGi is presented, followed by an illustrative usage case for a home networking environment.
TOPICS IN CIRCUITS FOR COMMUNICATIONS PUBLISHED IN COLLABORATION WITH THE IEEE CIRCUITS AND SYSTEMS SOCIETY - CHALLENGES IN THE DESIGN OF HIGH-SPEED CLOCK AND DATA RECOVERY CIRCUITS - The authors describe the challenges in the design of monolithic clock and data recovery circuits used in high-speed transceivers. Following an overview of general issues, the task of phase detection for random data is addressed. Next, Hogge, Alexander, and half-rate phase detectors are introduced and their trade-offs outlined. Finally, a number of clock and data recovery architectures are presented.
ACCEPTED FROM OPEN CALL - A SURVEY ON SENSOR NETWORKS - Recent advancement in wireless communications and electronics has enabled the development of low-cost sensor networks. The sensor networks can be used for various application areas (e.g., health, military, home). For different application areas, there are different technical issues that researchers are currently resolving.
ACCEPTED FROM OPEN CALL - BROADBAND ACCESS OVER CABLE FOR NEXT-GENERATION SERVICES: A DISTRIBUTED SWITCH ARCHITECTURE - The hybrid fiber coax architecture deployed by the cable service providers has been successful in capturing a substantial piece of the residential broadband access market. The authors describe an evolution path to enhance the HFC plant to provide, initially, Gigabit Ethernet (and eventually multi-Gigabit Ethernet) on the trunk and feeder portions, and 100 Mb-s Ethernet on the subscriber drops.
ACCEPTED FROM OPEN CALL - AN ADAPTIVE NON-AWGN SSMA RECEIVER - This article deals with the issue of optimum detection of known SS signal in nonwhite noise and-or narrowband interference. Prior to detection, the input signal is whitened according to the reciprocal of an interfering spectrum, I(z)
