A Unified Study Of Epidemic Routing Protocols And Their Enhancements, Zuyong Feng, Kwan-Wu Chin

Faculty of Informatics - Papers (Archive)

Epidemic protocols belong to a class of routing paradigm that have wide ranging applications in Delay Tolerant Networks (DTNs) due to their simplicity, low delays, and little to no reliance on special nodes. To this end, a comprehensive study of their performance will serve as an important guide to future protocol designers. Unfortunately, to date, there is no work that studies epidemic routing protocols using a common framework that evaluates their performance objectively using the same mobility model and parameters. To this end, we study four categories of epidemic routing protocols. Namely, P-Q epidemic, epidemic with Time-To-Live (TTL), epidemic with …

Faculty of Informatics - Papers (Archive)

Across the globe, educational institutions are adopting e-learning tools into their curricula to cater to the ever-growing demand for technology inside the classrooms. Where traditional blackboards have been replaced by virtual whiteboards and library books by online resources, teachers are trying hard to cope with the growing competition from technology outside the classroom that has captured their students’ attention and imagination, with more technology, perhaps increasing student dependency. However, the author’s previous research has shown that engaging e-learning tools to enhance student learning experience is not enough as it has negative impact on students’ attitude towards e-cheating, disillusioning their awareness …

Public Service Reform Through E-Government: A Case Study Of 'E-Tax' In Japan, Akemi T. Chatfield

Faculty of Informatics - Papers (Archive)

There is a growing interest in the debate over whether or not e-government has a transformational impact on government performance, governance, and public service, as we addressed this very issue at the 2007 ECEG. However, e-government research results on the transformational impact are mixed. This may be an apt reflection of either the early stages of e-government development or the newness of e-government research field or both. Our research goal as scholars of e-government must be to penetrate appearances to ascertain whatever lessons and meanings might lie beneath. This paper is an initial attempt toward achieving this goal. The main …

A Simulation Study On The Energy Efficiency Of Pure And Slotted Aloha Based Rfid Tag Reading Protocols, Alejandro Ruiz-Rivera, Dheeraj Klair, Kwan-Wu Chin

Faculty of Informatics - Papers (Archive)

This paper studies the energy efficiency of twelve Pure and Slotted Aloha tag reading protocol variants via simulation. We compare their energy consumption in three collision resolution phases: 1) success, 2) collision, and 3) idle. Our extensive simulation results show that Pure Aloha with fast mode and muting has the lowest energy consumption, and hence is most suited for deployment in energy-constrained environments.

Active Exploration Of Emerging Themes In A Study Of Object-Oriented Requirements Engineering: The 'Evolutionary Case' Approach, Linda L. Dawson

Faculty of Informatics - Papers (Archive)

The evolutionary case approach provides a framework for qualitative case study research in information systems (IS). It uses revelation, reinforcement, reflection and re-examination to explicitly explore emerging themes in interpretive case study research.

The method is based on the progressive development of a theoretical model grounded initially in the literature and then refined using sequential case studies grounded in practice. The method addresses the gap which often separates data from conclusions in qualitative case study research by documenting the “revealed” and “reinforced” changes in the theoretical model as it evolves from the empirical data.

The paper provides an illustrative study …

The Importance Of Community Engagement In Policy Development: An Australian Case Study, Alison Norris, Mark Freeman

Faculty of Informatics - Papers (Archive)

The Australian Domain Name Administrators have launched a new domain name space designed specifically for community groups to develop community Websites for the benefit of the local community. The purpose of the scheme under which these domains are issued is to link community members through community-managed Websites, and to encourage broad community participation and engagement. Despite broad community engagement during initial development, many changes have since been made to the policy governing these new domain names. This paper presents an overview of the scheme under which these community domains can be used, and identifies the changes made to the policy …

A Comparative Study Of The Direct Boundary Element Method And The Dual Reciprocity Boundary Element Method In Solving The Helmholtz Equation, Song-Ping Zhu, Yinglong Zhang

Faculty of Informatics - Papers (Archive)

In this paper, we compare the direct boundary element method (BEM) and the dual reciprocity boundary element method (DRBEM) for solving the direct interior Helmholtz problem, in terms of their numerical accuracy and efficiency, as well as their applicability and reliability in the frequency domain. For BEM formulation, there are two possible choices for fundamental solutions, which can lead to quite different conclusions in terms of their reliability in the frequency domain. For DRBEM formulation, it is shown that although the DBREM can correctly predict eigenfrequencies even for higher modes, it fails to yield a reasonably accurate numerical solution for …

A Study On Sound Source Apparent Shape And Wideness, Guillaume Potard, Ian Burnett

Faculty of Informatics - Papers (Archive)

This work is intended as an initial investigation into the perception of wideness and shape of sound sources. A method that employs mUltiple uncorrelated point sources is used in order to form "sound shapes". Several experiments were carried out in which, after some initial training, subjects were asked to indicate the shapes that were being played. Results indicate that vertical and horizontal source wideness are easily perceived and scenes that use broad sound sources are preferred 70% of the time over point source versions. However, shape perception was found to be ambiguous except for certain types of signals where results …

A Study Of Continuous Pq Disturbance Levels In Mv/Lv Distribution Systems, Victor J. Gosbell, D A. Robinson

Faculty of Informatics - Papers (Archive)

Distribution Network Service Providers need to be aware of the general variation of PQ disturbances across their network, from the sites as diverse as the MV bus bar of a zone substation, the end of a MV feeder, and at the near and far ends of LV mains. This paper develops an understanding of PQ variations across such a system from survey results correlated with approximate analysis used to assign a PQ disturbance ranking to each site. The work will concentrate on continuous PQ disturbances, defined as those due to load current effects, for example voltage deviations, unbalance, fluctuations and …
