To aid the early adoption of ATM technology as a local area network the ATM Forum has defined the LAN Emulation over ATM specification which aims to present a service interface more compatible with that of previous LANs. This document describes and defines a set of services -LAN Emulation Servicestogether with the components used for their provision. The paper reports on an implementation of th...

A software defined radio (SDR) prototype based on a multiprocessor architecture (MPA) is developed. Software for Japanese personal handy phone system (PHS) of a 2G mobile system, and IEEE802.11 wireless LAN, which has much wider bandwidth than the 2G systems, is successfully implemented. Newly developed flexible-rate pre-/post-processor (FR-PPP) achieves the flexibility and wideband performance...

The IEEE 802.11 wireless LAN standard specifies which messages shall be exchanged between an access point and a station to support mobility. However, the implementation of mobility in the wired part of the network, i.e. the distribution system or inter-access point protocol, is not specified. This paper presents and evaluates different options for the implementation of the distribution system u...

Transport protocols currently in use do not have any explicit support for the compressed video/audio traac over the new high-speed network, 100VG-Any LAN. They do not solve the unbounded jitters for a continuous stream and skew between two synchronized streams problems introduced by the underlying LAN. They also do not provide any QoS guarantees to the applications. The VGAnet Suite provides th...

A standardization body (CAPE-OPEN Laboratories Network – CO-LaN) has been established to maintain and disseminate the software standards in the Computer Aided Process Engineering (CAPE) domain that have been developed in the international projects CAPE-OPEN and Global CAPE-OPEN. The CO-LaN ensures that software tools used by the process industries reach a level of interoperability that will hel...

The low cost and easy deployment of Wireless LAN 802.11 standard means it becomes more and more popular, but it has a vital drawback with regard to Quality of Service (QoS). QoS defines the ability of network to introduce consistent services for data transmission, and is evaluated in terms of specific parameters such as jitter, delay, and packet loss. These parameters describe data traffic qual...

The present study investigated simultaneous processing of language and music using visually presented sentences and auditorily presented chord sequences. Music-syntactically regular and irregular chord functions were presented synchronously with syntactically correct or incorrect words, or with words that had either a high or a low semantic cloze probability. Music-syntactically irregular chord...

This dissertation presents two novel contributions in the area o...

Wireless networks are very common, both for organizations and individuals. Many laptop computers have wireless cards pre-installed for the buyer. The ability to enter a network while mobile has great benefits. However, wireless networking has many security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into non-wireless net...

This paper describes a methodology for designing interconnected LAN/MAN networks with the objective of minimizing the average network delay. We first consider IEEE 802 standard LAN’s interconnected by transparent bridges. These bridges are required to form a spanning tree topology. We propose a simulated annealing-based algorithm for designing minimum delay spanning tree topologies. In order to...
