Superphony: towards ubiquitous audio communication services
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 728-731
With the expansion of mobility in communication technologies, the increasing individual audio solicitations require a definition of priorities in audio information. A new concept called superphony is identified which improves communication abilities by reconstructing an audio sphere around each user and filtering audio information based on user and environment profiles. Requirements and elements f......

A service-based architecture for in-vehicle telematics systems
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 741-742
The growing needs to access information in remote, mobile environments have sparked interests in so-called In-Vehicle Telematics Systems (IVTS). These relatively new systems have the potential to deliver computing facilitates to road vehicles, which may include in-vehicle infotainment, route-guidance and navigation and the provision of vital information resources used by fleet haulage companies an......

Whoops!: a clustered Web cache for DSM systems using memory mapped networks
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 806-811
We present Whoops!, a clustered Web cache prototype based on SciFS, a distributed shared memory (DSM) that benefits from the high performances and the remote addressing capabilities of memory mapped networks like Scalable Coherent Interface (SCI). Whoops! uses the DSM for all Web cache management and cache storage. Using a memory mapped network and a DSM programming model allows us to investigate ......

The impact of data aggregation in wireless sensor networks
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 575-578
Sensor networks are distributed event-based systems that differ from traditional communication networks in several ways: sensor networks have severe energy constraints, redundant low-rate data, and many-to-one flows. Data-centric mechanisms that perform in-network aggregation of data are needed in this setting for energy-efficient information flow. In this paper we model data-centric routing and c......

Resource-sharing and service deployment in virtual data centers
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 666-671
The expectation of a global presence of services leads to the need for large numbers of service instances allocated in a multitude of regional data centers in order to provide sufficient service capacity close to where the demand occurs. Scale of service instances is anticipated growing /spl Gt/10/sup 4/ raising new challenges for control and management. Pragmatically, it must become much easier t......

Event-driven coordination of real-time components
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 589-594
The coordination paradigm has been used extensively as a mechanism for software composition and integration. However, relatively little work has been done for the cases where the software components involved have real-time requirements. The paper presents an extension to a state-of-the-art controller event-driven coordination language with real-time capabilities. It then illustrates the expressive......

Mobility of context for project teams
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 391-395
In the last decade, bureaucratic organizational hierarchies increasingly have been replaced with flatter organizational forms, bringing together people from different disciplines to form project teams within and between organizations. Distributed project teams often are self-configuring networks of mobile and "fixed" people, devices, and applications. They are the natural next step in the evolutio......

Implementation of ECC/ECDSA cryptography algorithms based on Java card
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 272-276
This paper describes the implementations and test results of elliptic curve cryptography (ECC) and elliptic curve digital signature algorithm (ECDSA) algorithms based on Java card. A 163-bit ECC guarantees as secure as the 1024-bit Rivest-Shamir-Adleman (RSA) public key algorithm, which has been frequently used until now. According to our test results, the 163-bit ECC processing time is about five......

The design of interactive negotiation agent on the Web
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 176-181
Because of the growth of Internet commerce, individual online transactions will grow rapidly. So in this paper we propose an interactive negotiation agent system on the Internet to help buyers make decisions. We use multi-attribute utility theory as the basic decision making strategy and the theorem is useful for the multicriteria decision. We stated the user goal that can be divided into several ......

OCEAN: Object Communication Environment for Arbitrary Network
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 162-166
In recent years, information devices with network communication ability have become very popular and many people actually own such devices. Those information devices, however do not share users' data in spite of their communication ability. This paper proposes OCEAN (Object Communication Environment for Arbitrary Network), which provides liaison of objects stored in each device according to their ......
