Ultra-Low Power
Computing System for Wireless Devices
by P. J. Hawrylak, L. Mats, J. T. Cain, A. K. Jones, S. Tung, M. H. Mickle
Abstract
- Wireless battery-powered devices require an active receiver in order to
receive and decode incoming messages. An active receiver consumes the majority
of the power, limiting the time between battery changes. In many cases,
particularly, sensor networks, automatic meter reading, and RFID tags, battery
replacement is impossible or inconvenient. This work describes a hardware and
software system, called a software receiver that replaces the active receiver.
The software receiver consumes almost no power when not decoding a message. The
software receiver increases the lifetime of wireless battery-powered device, to
more than that of the average person.

A Swarm Quality of Service Based Multi-Path Routing Algorithm (SAMRA) for
Wireless Ad Hoc Networks
by A. Mellouk, S. Ziane, P. Lorenz
Abstract
- With a
widespread development of multimedia applications in mobile ad hoc networks,
there is an increasing needs for QoS guarantees. Therefore protocols that are
designed for these networks should be more greatly involved in satisfying
application needs while optimizing network resources. This task is rather
difficult due to the highly dynamic topology of mobile ad hoc networks and their
limited resources. Actually, different routing algorithms are proposed in order
to route various kinds of sources (such as voice, video, or data) with diverse
traffic characteristics and Quality of Service Requirements (QoS). The goals of
QoS routing are in general twofold: selecting routes with satisfied QoS
requirement, and achieving global efficiency in resource utilization. The
prediction of these goals in real time is quite difficult, making the
effectiveness of “traditional” protocols based on analytical models questionable.
In this paper we first discuss some key design considerations in providing QoS
routing support, and present a review of previous work addressing the problem of
route selection in interaction with QoS constraints. We then devise a solution
based on swarm intelligence paradigm based on reinforcement learning approach
that we find more adapted for this kind of problems. Finally, we discuss some
possible future directions for providing efficient QoS routing mechanisms in
wireless ad hoc networks.

An
Introduction to High-Level Stochastic Activity Networks
by M. A. Azgomi, A. Movaghar
Abstract
- Stochastic activity networks (SANs) are a powerful and flexible extension of
Petri nets. However, SANs facilities are not enough high-level for modelling and
analysis of complex and large-scale systems. In order to provide such high-level
modelling facilities, we have defined high-level extensions for SANs. We intend
to preserve all capabilities of SANs for performance and dependability
evaluations in these new extensions. In this paper, we present a brief
introduction to these high-level extensions, including hierarchical stochastic
activity networks (HSANs), coloured stochastic activity networks (CSANs), and
object stochastic activity networks (OSANs). Some properties, examples and
applications of these models and their analysis methods will also be presented.

Toward Peer to Peer Platform Integration based on OWL Ontology and Roaming
Service
by Y. Djaghloul, Z. Boufaida
Abstract
- In this paper, we present our approach to build a semantic profile for the
peer in order to integrate the peer-to-peer platforms. Our approach combines the
use of a semantic peer profile and a specific roaming service. The semantic
profile uses the well-known notations in the P2P area, and provides a global
ontology that puts a clear separation between the platform specific
characteristics and the logical ones. In order to enable the navigation of the
peer across platforms, a roaming service is added. The latter deals with the
platform specification and ensure a transparency navigation between platforms by
managing the proposed ontology. In addition, the profile uses the ontology
paradigm to give a semantic presentation and enhances the semantic of the Peer
structure. The ontology is created by using an ontology development process that
produces a validate OWL document. Our approach is validated and tested by
extending two P2P platforms with our implementation.

by M. Singh, S. Bawa, S.C. Saxena
Abstract
- This research analyzes trends in network security through an investigation of
reactive and proactive network security strategies. Many of common practices
have been studied, analyzed, compared and reported in this work. A proactive
network surveillance framework is proposed. The framework consists of five
layers addressing security at various levels following the onion model of
defense. Successive layers of defense use different technologies. The inner
layers of defense can support the outer layer and an attacker must breach each
line of defense in turn. This gives an engineering solution, which emphasizes
redundancy - a system that keeps working even when a single component fails.
This will lead to self-healing and self-defending network infrastructure thus
emphasizing preventive mode of security.

OntoWer: An Ontology based Web Application Reverse-Engineering approach
by S. M. Benslimane, M. Mimoun, D. Bouchiha, D. Benslimane
Abstract
- Most Web applications are developed under tight schedules and in a rapidly
evolving environment. The maintenance of such applications becomes problematic
as the complexity of the Web application grows. Creating appropriate design and
architecture models is the key for efficiently managing and supporting the
evolution of Web applications. Researchers have identified the need to apply
reverse engineering techniques to already existing Web applications to create
abstract design models. The reverse engineering of Web sites has been addressed
in various ways. In this paper, we propose OntoWer, an ontology-based Web
application reverse engineering approach to deduce the conceptual schema of Web
application. Starting from an analysis Web HTML pages, it uses domain ontology
to generate a conceptual schema for modeling the corresponding Web application.
It consists of three phases: i) the extraction of candidate elements, ii) the
identification of relevant ontological constructs, and iii) the generation of
conceptual schema of the Web application.

A
Comparative Analysis of Website Features in the Healthcare Sector
by Z. Tanrıkulu
Abstract
- Healthcare is one of the most essential states in every part of our daily
lives. Therefore, healthcare business getting more complex every day and the
needs of the information systems are becoming more crucial.
Is it possible to introduce a new information technology into inpatient care
settings in an attempt to improve access to information and communication? Are
there any technical and usability limitations of having your health status
monitored on the Internet, or being able to consult a specialist without having
to go to a health center? Therefore, what are the criteria for having a good
website?
This research aims to provide comparative analysis of current websites in the
healthcare sector. To achieve that, twenty hospitals have been compared
according to their utilization of the Internet. Websites of top five hospitals
have also been used in the analysis to represent standardized service quality.
In this paper, you can find the details of technical specifications being used
to automate some time-consuming jobs and the websites of reputable healthcare
organizations.

Selling Culture: Implementation of e-Commerce and WAP-based Prototypes
by K. Zafeiri, D. Gavalas, A. Balla
Abstract
- Museum stores represent integral parts of the museums that have also a lot to
benefit from a successful presence on the web arena. In addition to traditional
web sites, carefully designed electronic commerce (e-commerce) sites may
increase the potential of museum stores offering possibilities for on-line
shopping and other commercial functions. In parallel, the recent convergence of
the traditionally separate technologies of the Internet and mobile telephony has
brought the concept of ‘wireless Internet’ into the spotlight. Within this
context, ‘mobile commerce’ (m-commerce) is a relatively new trend that
represents a natural extension of e-commerce into the wireless world. M-commerce
refers to electronic business transactions and differentiates from e-commerce
since it involves the use of mobile devices and wireless medium rather than
wired. The unique characteristics of mobile computing bring forward new
challenges and opportunities for museum stores. This article presents the design
and implementation of an e-commerce and an m-commerce museum shop application.
The aim is to evaluate and compare the two applications in terms of several
parameters, such as available technologies, strengths and limitations, design
requirements, usability, interaction speed, usage cost, etc and also to identify
ways for enhancing the potential of such applications and designing successful
and profitable business models.

Classification
Techniques Applied to Hydrocarbon Data
by J. G. Sumrall, R. R. Chakravarthy, B. B. Joshi
Abstract
- This project compares the efficiency of various current classification
techniques on hydrocarbons retrieved from oil wells and also isolates features
that can give good classification. The classification of samples from oil wells
is one of the major classification problems in the oil industry and contributes
significantly to the estimation of the nature of output of an oil well.
Classification is based on certain physical and chemical properties. Ideally, it
is desired to obtain a high number of Black Oil samples as that shows if the oil
well is potentially a good strike. If the classification is not done accurately,
it leads to inaccurate estimation of the production and hence, has its own
economic and financial implications.
In this project, we attempt classification in two parts – classify the data into
two major groups – Black Oil and Non Black Oil, classify Non Black Oil group
into 3 sub-groups – Wet gas, Dry gas and Volatile oil. We determine which
features of the hydrocarbons have the best discriminatory power and use these to
test various classifiers. We show how some linear classifiers consistently
perform better than the others and determine the best classification technique
for these types of data.
