Network layer access control for context-aware IPv6 applications

As part of the Lancaster GUIDE II project, we have developed a novel wireless access point protocol designed to support the development of next generation mobile context-aware applications in our local environs. Once deployed, this architecture will allow ordinary citizens secure, accountable and convenient access to a set of tailored applications including location, multimedia and context based services, and the public Internet. Our architecture utilises packet marking and network level packet filtering techniques within a modified Mobile IPv6 protocol stack to perform access control over a range of wireless network technologies. In this paper, we describe the rationale for, and components of, our architecture and contrast our approach with other state-of-the- art systems. The paper also contains details of our current implementation work, including preliminary performance measurements

IMPLEMENTATION OF WIRELESS LAN IN UTP

This paper, entitled Implementation ofWireless LAN in UTP environment, looks into the way to implement wireless network in UTP. The main objectives ofthis project are to provide mobile network and internet access using university's network system to students and lecturers and to make it easier and convenient for student to download lecture notes and for lecturers to upload them. Currently, there is no wireless LAN access in UTP environment that can be use by students and staff as alternative opportunity to access and share instant information. Therefore, this project research area is to find out the way to implement wireless LAN using secure Wi-Fi in UTP external environment. For this study, the scope is narrow down to the architecture and design ofwireless LAN network and its developing methodology. Anetwork simulation tool called Network Simulator version 2, or simply known as ns-2, is used to test the efficiency and functionality ofthe designed network. The outcome ofthis project is a good network architecture design that will give high network performance to all users in UTP

MVNC: A Multiview Network Computer Architecture

In this paper, MVNC, a multiview network computer system for a high usability thin-client computing environment, is introduced. MVNC uses a revised SBC model to offer a new framework for thin client computing. MVNC can be used as a full functional Windows machine, or used as a Linux workstation, or a~graphic terminal. Its multiview work style is achieved by the attempts on GUI seamless integration technology, device integration technology and local video playback support. MVNC is implemented in an embedded Linux environment using a MIPS-4KC microprocessor. Test results on video application show that MVNC system uses its client hardware more efficiently and the load of MVNC server is lightened

Virtualisation and Thin Client : A Survey of Virtual Desktop environments

This survey examines some of the leading commercial Virtualisation and Thin Client technologies. Reference is made to a number of academic research sources and to prominent industry specialists and commentators. A basic virtualisation Laboratory model is assembled to demonstrate fundamental Thin Client operations and to clarify potential problem areas

THINC: A Remote Display Architecture for Thin-Client Computing

Rapid improvements in network bandwidth, cost, and ubiquity combined with the security hazards and high total cost of ownership of personal computers have created a growing market for thin-client computing. We introduce THINC, a remote display system architecture for high-performance thin-client computing in both LAN and WAN environments. THINC transparently maps high-level application display calls to a few simple low-level commands which can be implemented easily and efficiently. THINC introduces a number of novel latency-sensitive optimization techniques, including offscreen drawing awareness, command buffering and scheduling, non-blocking display operation, native video support, and server-side screen scaling. We have implemented THINC in an XFree86/Linux environment and compared its performance with other popular approaches, including Citrix MetaFrame, Microsoft Terminal Services, SunRay, VNC, and X. Our experimental results on web and video applications demonstrate that THINC can be as much as five times faster than traditional thin-client systems in high latency network environments and is capable of playing full-screen video at full frame rate

Quality Analysis of Mobile Applications

Mobile applications are defined and different types of mobile applications are identified. Characteristics of quality are defined and their indicators are constructed to measure levels. Take into account 11 parameters analysis for mobile applications, which are arranged using weights and do a detailed analysis of the system of weights. For SMSEncrypt application performance measurement is done using an aggregate indicator based on the obtained weights system.Mobile, Application, Quality, Analysis, Indicator
