The collaborative editing of documents by teams that are distributed over many locations is a very common task nowadays. Consequently, it is a primary requirement to create editors that support that task. These group editors should be usable seamlessly in local area networks (LANs), in wide area networks (WANs) and with mobile computers. In this article we want to draw attention to the implicat...
This paper focuses on the Call Control for the establishment and release of isochronous calls within the DAMS network (ESPRIT project #2146), a distributed ISDN PBX over an FDDI-II backbone optical ring that supports both isochronous and asynchronous traffic generated by ISDN terminals, LAN terminals, and Bandwidth On Demand (BOD) terminals. After a general overview of the DAMS network architec...
Predicting coverage in wireless local area networks with obstacles using kriging and neural networks
In this paper, a new approach based on ordinary kriging is proposed to predict network coverage in wireless local area networks. The proposed approach aims to reduce the cost of active site surveys by estimating path loss at points where no measurement data is available using samples taken at other points. To include the effect of obstacles on the covariance among points, a distance measure is ...
Users need high speed and low latency transmission for new applications. Since Ethernet is the dominant LAN technology, service providers wish to offer new Ethernet services as Layer 2 Virtual Private Network (L2VPN), to meet the requirements of these applications. MultiProtocol Label Switching (MPLS) is one of the most suitable technologies to deploy L3VPN and can also be used to realize L2VPN...
Wireless communication networks are relatively inexpensive to deploy, easy to install, and offer high flexibility over wired communication networks. This is why wireless communication is a popular choice of communication for Local and Wide Area Networks (LANs/MANs), termed Wireless LAN/MAN (WLAN/WMAN). Efficient mechanisms are needed to ensure an acceptable level of wireless communication perfo...
1 A comparison of ABR and UBR to support TCP tra c Sam Manthorpe and Jean-Yves Le Boudec Abstract| This paper compares the performance of ABR and UBR for providing high-speed network interconnection services for TCP tra c. We test the hypothesis that UBR with adequate bu ering in the ATM switches results in better overall goodput for TCP tra c than explicit rate ABR for LAN interconnection. Thi...
Distributed computing systems which rely on message passing for communication between computers, require low latency in the communications network in order to be eeective. The multichannel ring network was previously proposed as a local area network topol-ogy for use in such distributed systems. In this paper we describe how wormhole routing can be used in the multichannel ring to decrease the ...
In the course of last decade, wireless sensor networks (WSNs) have grabbed attention of both academic research community and industrial users. Such networks provide a broad range of applications, making them of great significance. Energy is the greatest concern of such battery-operated networks as it directly influences the lifetime of the network. As packet dropping due to congestion has a dra...
The system is generated to use their friends to communicate with them within a LAN system and can be hosted on server throughout to the friend circle. The system is designed to use to determine the distance between the two users on Google maps. This system helps us to connect with our close ones .The traditional way of sharing things can be replaced by our new system. The history of data can be...
This paper describes an architecture where access to heterogeneous mobile networks is granted on the basis of online payment methods. Access methods for GSM networks were designed for subscribed post-pay customers. With the Intelligent Networks (IN) technology, the operators could also offer services to prepay customers. Now online payment might provide additional means for network access. We s...
