An intra-vehicular wireless multimedia sensor network for smartphone-based low-cost advanced driver-assistance systems
Advanced driver-assistance system(s) (ADAS) are more prevalent in high-end vehicles
than in low-end vehicles. Wired solutions of vision sensors in ADAS already exist, but are costly
and do not cater for low-end vehicles. General ADAS use wired harnessing for communication;
this approach eliminates the need for cable harnessing and, therefore, the practicality of a novel
wireless ADAS solution was tested. A low-cost alternative is proposed that extends a smartphone’s
sensor perception, using a camera-based wireless sensor network. This paper presents the design
of a low-cost ADAS alternative that uses an intra-vehicle wireless sensor network structured by a
Wi-Fi Direct topology, using a smartphone as the processing platform. The proposed system makes
ADAS features accessible to cheaper vehicles and investigates the possibility of using a wireless
network to communicate ADAS information in a intra-vehicle environment. Other ADAS smartphone
approaches make use of a smartphone’s onboard sensors; however, this paper shows the application
of essential ADAS features developed on the smartphone’s ADAS application, carrying out both
lane detection and collision detection on a vehicle by using wireless sensor data. A smartphone’s
processing power was harnessed and used as a generic object detector through a convolution neural
network, using the sensory network’s video streams. The network’s performance was analysed to
ensure that the network could carry out detection in real-time. A low-cost CMOS camera sensor
network with a smartphone found an application, using Wi-Fi Direct, to create an intra-vehicle
wireless network as a low-cost advanced driver-assistance system.DATA AVAILABLITY STATEMENT : Publicly available datasets were analysed in this study. There data can

D1.1 DEMAND ASSESSMENT FRAMEWORK
This report proposes the initial draft of the LeADS ADS Framework composed by three major elements; identification and definition of technologies in scope; skills included under those technologies, and definition of job roles, where other skills frameworks are considered for comparison and alignment. The report summarises the first workshop held by the project with external constituencies even though the feedback will be incorporated in the final version of the framework, where the layer of job roles will be completed, and the others revised according to additional input. This framework serves as reference for the next step in LeADS: the assessment of the demand and the supply
An intra-vehicular wireless multimedia sensor network for smartphone-based low-cost advanced driver-assistance systems
Advanced driver-assistance systems (ADAS) are more prevalent in high-end vehicles than in low-end
vehicles. The research proposes an alternative for drivers without having to wait years to gain access
to the safety ADAS offers. Wireless Multimedia Sensor Networks (WMSN) for ADAS applications
in collaboration with smartphones is non-existent. Intra-vehicle environments cause difficulties in
data transfer for wireless networks where performance of such networks in an intra-vehicle network is
investigated.
A low-cost alternative was proposed that extends a smartphone’s sensor perception, using a camera-
based wireless sensor network. This dissertation presents the design of a low-cost ADAS alternative
that uses an intra-vehicle wireless sensor network structured by a Wi-Fi Direct topology, using a
smartphone as the processing platform. In addition, to expand on the smartphone’s other commonly
available wireless protocols, the Bluetooth protocol was used to collect blind spot sensory data, being
processed by the smartphone. Both protocols form part of the Intra-Vehicular Wireless Sensor Network
(IVWSN).
Essential ADAS features developed on the smartphone ADAS application carried out both lane
detection and collision detection on a vehicle. A smartphone’s processing power was harnessed and used as a generic object detector through a convolution neural network, using the sensory network’s
video streams. Blind spot sensors on the lateral sides of the vehicle provided sensory data transmitted
to the smartphone through Bluetooth.
IVWSNs are complex environments with many reflective materials that may impede communication.
The network in a vehicle environment should be reliable. The network’s performance was analysed to
ensure that the network could carry out detection in real-time, which would be essential for the driver’s
safety. General ADAS systems use wired harnessing for communication and, therefore, the practicality
of a novel wireless ADAS solution was tested.
It was found that a low-cost advanced driver-assistance system alternative can be conceptualised by
using object detection techniques being processed on a smartphone from multiple streams, sourced
from an IVWSN, composed of camera sensors. A low-cost CMOS camera sensors network with a
smartphone found an application, using Wi-Fi Direct to create an intra-vehicle wireless network as a
low-cost advanced driver-assistance system.Dissertation (MEng (Computer Engineering))--University of Pretoria, 2021.Electrical, Electronic and Computer EngineeringMEng (Computer Engineering)Unrestricte
Using mobile computing for construction site information management
PhD ThesisIn recent years, construction information management has greatly benefited from
advancesin Information and Communication Technology (ICT) increasing the speed of
information flow, enhancing the efficiency and effectiveness of information
communication, and reducing the cost of information transfer. Current ICT support has
been extended to construction site offices. However, construction projects typically take
place in the field where construction personnel have difficulty in gaining access to conventional information systems for their information requirements. The advances in affordable mobile devices, increases in wireless network transfer speeds and
enhancements in mobile application performance, give mobile computing a powerful
potential to improve on-site construction information management.
This research project aims to explore how mobile computing can be implemented to
manage information on construction sites through the development of a framework.
Various research methods and strategies were adopted to achieve the defined aim of this
research. These methods include an extensive literature review in both areas of
construction information management and mobile computing; case studies that
investigate construction information management on construction sites; a web-based
survey for the investigation of the existing mechanism for on-site information retrieval
and transfer; and a case study of the validation of the framework.
Based on the results obtained from the literature review, case studies and the survey,the developed framework identifies the primary factors that influence the implementation of mobile computing in construction site information management, and the inter relationships between those factors. Each of these primary factors is further divided into sub-factors that describe the detailed features of relevant primary factors. In order to explore links between sub-factors, the top-level framework is broken down into different sub-frameworks, each of which presents the specific links between two primary factors.
One of the applications for the developed framework is the selection of a mobile
computing strategy for managing on-site construction information. The overall selection procedure has three major steps: the definition of on-site information management objectives; the identification of mobile computing strategy; and the selection of appropriate mobile computing technologies. The evaluation and validity of the selection procedure is demonstrated through an illustrative constructions cenario

Conference Foreword
The annual Security Congress, run by the Security Research Institute at Edith Cowan University, includes the Australian Information Security and Management Conference. Now in its fifteenth year, the conference remains popular for its diverse content and mixture of technical research and discussion papers. The area of information security and management continues to be varied, as is reflected by the wide variety of subject matter covered by the papers this year. The papers cover topics from vulnerabilities in “Internet of Things” protocols through to improvements in biometric identification algorithms and surveillance camera weaknesses. The conference has drawn interest and papers from within Australia and internationally. All submitted papers were subject to a double blind peer review process. Twenty two papers were submitted from Australia and overseas, of which eighteen were accepted for final presentation and publication. We wish to thank the reviewers for kindly volunteering their time and expertise in support of this event. We would also like to thank the conference committee who have organised yet another successful congress. Events such as this are impossible without the tireless efforts of such people in reviewing and editing the conference papers, and assisting with the planning, organisation and execution of the conference. To our sponsors, also a vote of thanks for both the financial and moral support provided to the conference. Finally, thank you to the administrative and technical staff, and students of the ECU Security Research Institute for their contributions to the running of the conference
The feasibility of using virtual prototyping technologies for product evaluation
With the continuous development in computer and communications technology the use of
computer aided design in design processes is becoming more commonplace. A wide range of
virtual prototyping technologies are currently in development, some of which are commercially
viable for use within a product design process. These virtual prototyping technologies range
from graphics tablets to haptic devices. With the compression of design cycles the feasibility of
using these technologies for product evaluation is becoming an ever more important
consideration.
This thesis begins by presenting the findings of a comprehensive literature review defining
product design with a focus on product evaluation and a discussion of current virtual
prototyping technologies. From the literature review it was clear that user involvement in the
product evaluation process is critical. The literature review was followed by a series of
interconnected studies starting with an investigation into design consultancies' access and
use of prototyping technologies and their evaluation methods. Although design consultancies
are already using photo-realistic renderings, animations and sometimes 3600 view CAD
models for their virtual product evaluations, current virtual prototyping hardware and software
is often unsatisfactory for their needs. Some emergent technologies such as haptic interfaces
are currently not commonly used in industry. This study was followed by an investigation into
users' psychological acceptance and physiological discomfort when using a variety of virtual
prototyping tools for product evaluation compared with using physical prototypes, ranging from
on-screen photo-realistic renderings to 3D 3600 view models developed using a range of
design software. The third study then went on to explore the feasibility of using these virtual
prototyping tools and the effect on product preference when compared to using physical
prototypes. The forth study looked at the designer's requirements for current and future virtual
prototyping tools, design tools and evaluation methods.
In the final chapters of the thesis the relative strengths and weaknesses of these technologies
were re-evaluated and a definitive set of user requirements based on the documentary
evidence of the previous studies was produced. This was followed by the development of a
speculative series of scenarios for the next generation of virtual prototyping technologies
ranging from improvements to existing technologies through to blue sky concepts. These
scenarios were then evaluated by designers and consumers to produce documentary
evidence and recommendations for preferred and suitable combinations of virtual prototyping
technologies. Such hardware and software will require a user interface that is intuitive, simple,
easy to use and suitable for both the designers who create the virtual prototypes and the
consumers who evaluate them
Exploring traffic and QoS management mechanisms to support mobile cloud computing using service localisation in heterogeneous environments
In recent years, mobile devices have evolved to support an amalgam of multimedia applications and content. However, the small size of these devices poses a limit the amount of local computing resources. The emergence of Cloud technology has set the ground for an era of task offloading for mobile devices and we are now seeing the deployment of applications that make more extensive use of Cloud processing as a means of augmenting the capabilities of mobiles. Mobile Cloud Computing is the term used to describe the convergence of these technologies towards applications and mechanisms that offload tasks from mobile devices to the Cloud.
In order for mobile devices to access Cloud resources and successfully offload tasks there, a solution for constant and reliable connectivity is required. The proliferation of wireless technology ensures that networks are available almost everywhere in an urban environment and mobile devices can stay connected to a network at all times. However, user mobility is often the cause of intermittent connectivity that affects the performance of applications and ultimately degrades the user experience. 5th Generation Networks are introducing mechanisms that enable constant and reliable connectivity through seamless handovers between networks and provide the foundation for a tighter coupling between Cloud resources and mobiles.
This convergence of technologies creates new challenges in the areas of traffic management and QoS provisioning. The constant connectivity to and reliance of mobile devices on Cloud resources have the potential of creating large traffic flows between networks. Furthermore, depending on the type of application generating the traffic flow, very strict QoS may be required from the networks as suboptimal performance may severely degrade an application’s functionality.
In this thesis, I propose a new service delivery framework, centred on the convergence of Mobile Cloud Computing and 5G networks for the purpose of optimising service delivery in a mobile environment. The framework is used as a guideline for identifying different aspects of service delivery in a mobile environment and for providing a path for future research in this field. The focus of the thesis is placed on the service delivery mechanisms that are responsible for optimising the QoS and managing network traffic.
I present a solution for managing traffic through dynamic service localisation according to user mobility and device connectivity. I implement a prototype of the solution in a virtualised environment as a proof of concept and demonstrate the functionality and results gathered from experimentation.
Finally, I present a new approach to modelling network performance by taking into account user mobility. The model considers the overall performance of a persistent connection as the mobile node switches between different networks. Results from the model can be used to determine which networks will negatively affect application performance and what impact they will have for the duration of the user's movement. The proposed model is evaluated using an analytical approac
Prospects of Mobile Search
Search faces (at least) two major challenges. One is to improve efficiency of retrieving relevant content for all digital formats (images, audio, video, 3D shapes, etc). The second is making relevant information retrievable in a range of platforms, particularly in high diffusion ones as mobiles. The two challenges are interrelated but distinct. This report aims at assessing the potential of future Mobile Search. Two broad groups of search-based applications can be identified. The first one is the adaptation and emulation of web search processes and services to the mobile environment. The second one is services exploiting the unique features of the mobile devices and the mobile environments. Examples of these context-aware services include location-based services or interfacing to the internet of things (RFID networks).
The report starts by providing an introduction to mobile search. It highlights differences and commonalities with search technologies on other platforms (Chapter 1). Chapter 2 is devoted to the supply side of mobile search markets. It describes mobile markets, presents key figures and gives an outline of main business models and players. Chapter 3 is dedicated to the demand side of the market. It studies users¿ acceptance and demand using the results on a case study in Sweden. Chapter 4 presents emerging trends in technology and markets that could shape mobile search. It is the author's view after discussing with many experts. One input to this discussion was the analysis of on forward-looking scenarios for mobile developed by the authors (Chapter 5). Experts were asked to evaluate these scenarios. Another input was a questionnaire to which 61 experts responded. Drivers, barriers and enablers for mobile search have been synthesised into SWOT analysis. The report concludes with some policy recommendations in view of the likely socio-economic implications of mobile search in Europe.JRC.DG.J.4-Information Societ
