Service multiplexing and resource allocation in S-CDMA/PRMA LEO systems
- Trang 85-90
This paper studies an adaptive CDMA/PRMA protocol for satellite LEO systems. The new protocol is called S-CDMA/PRMA (satellite-code division multiple access/packet reservation multiple access). The goal is to integrate several types of traffic (voice, file transfer and Web) on the channel. This leads to a service multiplexing and resource allocation study. New permission probability control functi......

A secure approach for mobile agent migration control
- Trang 741-746
The mobile agent paradigm is a promising technology for smart e-commerce of the next generation. However, security-related issues must be satisfactorily solved before they come into full commercial use. We propose a secure approach for mobile agent migration control based on passport and visa (P/V). P/V as up-to-date digital credentials not only serve the agent-host authentication purpose, but als......

Autonomous consistency coordination technique among distributed database systems for achieving high reliability
- Trang 637-644
Recently, market and user preferences have been drastically changing; user oriented production and logistic systems such as the supply chain management system have been required. In this kind of system, different subsystems with heterogeneous level of reliability have to coexist while trying to preserve the one click response and the flexibility in order to satisfy the frequently changing and hete......

Additive increase adaptive decrease congestion control: a mathematical model and its experimental validation
- Trang 849-854
Due to the fundamental end-to-end design principle of the TCP/IP for which the network cannot supply any explicit feedback, today the TCP congestion control algorithm implements an additive increase multiplicative decrease (AIMD) algorithm. It is widely recognized that the AIMD mechanism is at the core of the stability of end-to-end congestion control. In this paper we describe a new mechanism we ......

Network constrained smoothing: enhanced multiplexing of MPEG-4 video
- Trang 114-119
Interactive multimedia applications over multi-hop cell or packet-switched networks have strict bounds on delay, loss, and jitter. Much research has focused on how best to handle the networking issues related to supporting quality of service (QoS) contracts without compromising network efficiency, i.e. improving network utilisation, and reducing connection packet loss and late delivery. This paper......

How bad TCP can perform in mobile ad hoc networks
- Trang 298-303
Several recent studies have indicated that TCP performance degrades significantly in mobile ad hoc networks. This paper examines how badly TCP may perform in such networks and provides a quantitative characterization of this performance gap. Previous approaches typically made comparisons by ignoring the inherent dynamics such as mobility, channel error and shared-channel contention. Our work provi......

Intermediaries for the World-Wide Web: overview and classification
- Trang 231-236
Intermediaries are software entities deployed on Internet hosts of the wireline and wireless Web that intervene in the flow of information from clients to origin servers at the application level of the WWW. Intermediary systems fall under the general term of "middleware". Intermediaries represent a useful abstraction for the design and study of emerging software infrastructures for "next-generatio......

An efficient multiuser detection algorithm for CDMA signals
- Trang 150-154
In this paper, an efficient method for multiuser detection of CDMA signal is proposed, that provides soft output with remaining noise distribution close to the Gaussian. Therefore the proposed algorithm is efficient for both coded and uncoded signals. This algorithm is simulated for BPSK signals with random spreading. The performance of the receiver is analyzed in terms of BER and spectral efficie......

Tunable fiber Bragg grating-based a pair of m-sequence coding for optical CDMA
- Trang 713-718
A fiber-optical code-division multiple-access (FO-CDMA) scheme, which is based on spectral coding, is proposed. The spectral coding is based on the pseudo-orthogonality of FO-CDMA codes properly written in the fiber Bragg grating (FBG) devices. A pair of maximal-length sequence codes is used to exemplify the coding and correlation processing among FO-CDMA user codes. Cooperating with TDMA and the ......

EPDA-modeller: a tool for modelling a distributed programming environment
- Trang 245-250
We propose an architecture of a generic fault-tolerant graphical environment and a tool for modelling a concrete distributed environment. The generic environment provides support for the construction, configuration, execution, monitoring, and evolution of distributed applications. The environment can be installed to be robust to guarantee the continuity of its service in the presence of node failu......
