The continuous development of Internet bandwidth, communication and content variety have enabled peer-to-peer protocols to take place among the most heavily used protocols in the Internet, with BitTorrent as the current flagship. Recent research has focused on measuring Peer-to-Peer systems and proposing improvements and enhancements to existing protocol with the goal of ensuring rapid content distribution...
Intelligent climate control consists in monitoring and controlling climate parameters (temperature, humidity, ventilation, pressure) in certain environments, conforming to certain requirements. Monitoring and controlling the temperature is important for human health, for avoiding accidents and in industrial processes. This paper presents a solution for monitoring and controlling the temperature in...
This paper proposes an expert system to aid plant maintainers and operators personnel for solving hydroelectric equipments troubleshootings. The expert system was implemented into intelligent maintenance system called SIMPREBAL (Predictive Maintenance System of Balbina). The SIMPREBAL knowledge base, the architecture and the inference machine are presented in detail. The knowledge base is based on...
Analysising WEB Geographic Information System (WEBGIS) status, found that the existing problem in the current system, combine the SVG with the Ajax, propose a idea of constructing a new WEBGIS system. First introduce a variety of techniques used, SVG technology has such characteristics as small storage space and the strong intercommunication, illustrates the possibility of using this vector graphic...
This paper studies on a client / server wireless network model of hand-held mobile devices for land surveying and mapping industry, and accesses the credibility and methods of data communication between different programs through multi-threaded and socket. Key issues and technologies are discussed through practice, that wireless internet facilitate GIS data transfer, and multi-threaded applications...
Existing de-duplication solutions in cloud backup environment either obtain high compression ratios at the cost of heavy de-duplication overheads in terms of increased latency and reduced throughput, or maintain small de-duplication overheads at the cost of low compression ratios causing high data transmission costs, which results in a large backup window. In this paper, we present SAM, a Semantic-Aware...
In this paper the planning and development of a backend software for a Electronic Health Record (eHR) Management System is presented. The system is based on the well-known Google's Android open platform, that offers easy networking procedures and low design complexity. The aim of this work is to present the system's client, which operates on a mobile device (Android based) and acquires data from the...
This paper analyzed the shortages of S/KEY OTP system in mobile commerce identity authentication and suggested an improved one-time password system based on bidirectional virtual authorization in mobile application systems. On one hand, this suggestion can reduce the calculation stress of both client and server, accordingly increases the efficiency of authorization and withstands the DoS attack. On...
Client-server architecture is the common practice for online games where installed reliable servers provide the game logic. If the latency between two players through a server is large, the responsiveness of the game can become problematic. Consequently, performance as well as gaming experience can be unsatisfactory. In this paper, for client-server architecture we present a game state forwarding...
To improve the reliability and feasibility of web applications, performance testing is very important for satisfying users. For reducing the cost and improve the efficiency of performance testing, we propose a new reactivity-based performance testing framework in this paper. We also provide a complete approach to generate test cases automatically from original web logs. First our approach retrieves...
This paper proposes a web-based On Line Analyse Process (OLAP) structure due to the weaknesses of OLAP system within the conventional Client/Server(C/S) structure. Studied with actual examples, a multidimensional model of web-based OLAP drilling analysis system has been designed, by applying the methods of link between Office Web Components and analysis server, various OLAP analysis operation through...
Introduces the design and implementation of a Remote System for Parallel Computing.Based on Multi-platform.This system support remote operating and running Linux system parallel programes on Windows system and provide a kind of uniform mode for the applied customer to operation, The customer does not need to know the concrete structure of the parallel computing system,can operate the parallel system...
Network computing is changing rapidly these days. The mobile agent technology invented to overcome the complexity resulting due to the increasing size of network components that rises new network management schemes. Many prototype applications providing mobile agent capability have been proposed for being used in network management. E-commerce and information retrieval are some of them. The motive...
With recent advances in video encoding and network technology, media streaming services are getting popular. Media streaming system based on the traditional server/client or CDN architecture has a scalability problem, and peer-to-peer media streaming system using resources of peers in the system can provide better scalability. Previous media streaming services are suited to play stored contents such...
As demands for treating an access control on the client side, which is conventionally controlled by a server, increase, there is a need to treat query processing effectively and securely in an environment with limited resources. Access control that has been previously performed only focused on safety, and thus not much effort has been done to consider access control in terms of efficiency. This paper...
To meet the requirements of some intelligent vehicle monitoring system, the software integrates Global Position System (GPS), Geographic Information System (GIS) and Global System for Mobile communications (GSM) in the whole. The structure, network topology, functions, main technical features and their implementation principles of the system are introduced. Then hardware design of the vehicle terminal...
This paper describes a new type of authentication protocol and a system based on the protocol. Input transformation module is an universal service program installed in the client's. The module putout distinct output password or account for different website according to the same original user password or account and the secret website's identification code, And then, by using non-symmetric encryption,...
Spotify is a music streaming service offering low-latency access to a library of over 8 million music tracks. Streaming is performed by a combination of client-server access and a peer-to-peer protocol. In this paper, we give an overview of the protocol and peer-to-peer architecture used and provide measurements of service performance and user behavior. The service currently has a user base of over...
In this work we study the benefits of a peer- assisted approach to online backup applications, in which spare bandwidth and storage space of end- hosts complement that of an online storage service. Via simulations, we analyze the interplay between two key aspects of such applications: data placement and bandwidth allocation. Our analysis focuses on metrics such as the time required to complete a backup...
In recent years, the video streaming service has become one of the most important applications. The rapid growth of users raises a big challenge to the traditional client-server VoD service. In order to provide large scale VoD service with lower server bandwidth cost, P2P technology has been introduced to VoD service. P2P based VoD service provides the same user experience as the client-server mode...
