This paper designs a database middleware based on TCP/IP protocol. By the system validating of C/S structure on the service end, it solves the data secure problem of client connection configuration. With further study, it realizes the separation of client connection and database connection, and forms three-tie structures. Therefore it can expand applications to the Internet network. A client connection...
Today, Data Center Networks (DCNs) are re-architected in different new architectures in order to alleviate several emergent issues related to server virtualization and new traffic patterns, such as the limitation of bi-section bandwidth and workload migration. However, these new architectures will remain either proprietary or hidden in administrative domains, and interworking protocols will remain...
Data interactive service shall be required during the working process of distributed Heterogeneous robot for industry production line. The heterogeneity of bottom hardware and upper software between heterogeneous robots will be screened by introducing the CORBA technology of software development. integrated technology of heterogeneous robot system has been researched. As a result, data interactive...
Due to the advances in wireless networking and microelectronics, more and more smart objects are equipped with wireless networking as well as high computing capability. Heterogeneity of service protocols inhibits the interoperation among smart objects using different service protocols. Existing works overcome the heterogeneity by assuming that service protocols used are known in advance so that components...
This paper details an extension to the GridRPC API that responds both to the data management needs of distributed applications and to middleware interoperability. It provides a minimal set of functions to handle a large set of data operations: movements, replications, migrations, persistency and data prefetch, which can be used by clients or workflow systems for example. We trust that this API covers...
In this paper, we introduce a ubiquitous voice message broadcast system - called u-Paging, by combining the technique of location-awareness and the voice message delivery service in ubiquitous sensor network environment. To actualize the u-Paging service, specialized hardware and middleware architecture are proposed under the wire/wireless hybrid ubiquitous network.
This paper presents a mobile middleware that solves interoperability problems occurred in VoIP protocols (SIP, H.323, Jingle and their different vendor implementations) and uses distributed shared objects to overcome scarce resource problem of mobile devices.
This paper describes security extensions of various Windows components based on usage of FIPS 201 (PIV) smart cards. Compared to some other similar solutions, this system has two significant advantages: first, smart cards are based on FIPS 201 standard and not on some proprietary technology; second, smart card security extensions represent an integrated solution, so the same card is used for security...
In future buildings, all devices will be connected directly to the Internet, surrounding people with a Web of Things. That will bring the amazing possibility to control building facilities from any device with Internet access (PC, mobile phone, etc.). However, while it is already technically possible to connect devices directly to IP networks, most of home and building automation systems still use...
We address the problem of resource allocation in a large-scale cloud environment, which we formalize as that of dynamically optimizing a cloud configuration for green computing objectives under CPU and memory constraints. We propose a generic gossip protocol for resource allocation, which can be instantiated for specific objectives. We develop an instantiation of this generic protocol which aims at...
This work defines a HiSpeed File Transfer Protocol (FTP) designed for subwave-length metro optical networks. HiSpeed FTP improves TCP throughput, achieves a high rate in 10Gbps links and avoids penalizing transmission of small packets.
Pervasive computing is characterized by heterogeneous devices that usually have scarce resources requiring optimized usage. These devices may use different communication protocols which can be switched at runtime. As different communication protocols have different quality of service (QoS) properties, this motivates optimized self-adaption of protocols for devices, e.g., considering power consumption...
Cloud computing is an elastic computing model whereby users can lease computing and storage resources on demand from a remote infrastructure. Cloud computing is gaining popularity due to its low cost, high reliability and wide availability. However, a serious impediment to its wider deployment is the relative lack of effective data management services. The relatively slow access to persistent data...
This paper focuses on the implementation and performance analysis of a hardware/Software implementation of a Object Request Broker (ORB) to support a network of Distributed Smart Camera (DSC) systems. We present the overall system architecture as a part of the whole System on Chip (SoC) within FPGA. The performance analysis performed on a software as well as on our hybrid implementation is explained...
Current advances in portable devices, wireless technologies have created a mobile computing environment which is characterized by a large scale of dynamism. But mobile computing is quite different from traditional middleware while addressing the dynamic and pervasive aspects of mobile systems. This paper represents the experience of our project related to next generation middleware systems, with high...
This work discusses the adaptation of group-oriented messaging and chat technology for operation in serverless, multicast-capable mobile wireless architectures. The main goals are to allow group messaging and chat sessions to fragment/coalesce, operate through disrupted TCP conditions, and improve bandwidth utilization when multicast is available. In addition, the solution demonstrates proxying and...
Basing on the idea of intrusion masking and defense-in-depth, a generic architecture of survivable storage system is presented. The architecture includes 3 subsystems: storage strategy, user management and security module. Through analyzing the overall survivability of storage systems, and importing survivable requirement into the design phase of storage systems, security and other attributes is easily...
The IP Multimedia Subsystem (IMS) is a telecommunication middleware architecture that behaves as a docking station for a wide range of multimedia services. Several so-called killer applications have been envisioned for this platform such as multimedia group communications and location based services (LBS), but one of the most common business cases for IMS remains IPTV (Internet Protocol TV). Several...
This paper presents a recovery architecture for in-memory data management systems. Recovery in such systems boils down to solving two problems: retrieving and installing the last committed image of the crashed database on a new server and replaying the updates missing from the image. We improve recovery time with a novel technique called On-Demand Recovery, which removes the need to replay all missing...
Recognizing the value of an advanced metering infrastructure (AMI), utilities worldwide are deploying millions of smart meters. To better justify AMI investment, researchers have recognized the urgency to utilize the full potential of AMI to improve the quality of distribution management system (DMS) applications. However, the integration of AMI and DMS is a challenge as it entails different communication...
