Gradient Descent Localization In Wireless Sensor Networks, Nuha A.S. Alwan, Zahir M. Hussain
Gradient Descent Localization In Wireless Sensor Networks, Nuha A.S. Alwan, Zahir M. Hussain
Research outputs 2014 to 2021
Meaningful information sharing between the sensors of a wireless sensor network (WSN) necessitates node localization, especially if the information to be shared is the location itself, such as in warehousing and information logistics. Trilateration and multilateration positioning methods can be employed in two-dimensional and threedimensional space respectively. These methods use distance measurements and analytically estimate the target location; they suffer from decreased accuracy and computational complexity especially in the three-dimensional case. Iterative optimization methods, such as gradient descent (GD), offer an attractive alternative and enable moving target tracking as well. This chapter focuses on positioning in three dimensions using time-of-arrival …
Controlled Access To Cloud Resources For Mitigating Economic Denial Of Sustainability (Edos) Attacks, Zubair A. Baig, Sadiq M. Sait, Farid Binbeshr
Controlled Access To Cloud Resources For Mitigating Economic Denial Of Sustainability (Edos) Attacks, Zubair A. Baig, Sadiq M. Sait, Farid Binbeshr
Research outputs 2014 to 2021
Cloud computing is a paradigm that provides scalable IT resources as a service over the Internet. Vulnerabilities in the cloud infrastructure have been readily exploited by the adversary class. Therefore, providing the desired level of assurance to all stakeholders through safeguarding data (sensitive or otherwise) which is stored in the cloud, is of utmost importance. In addition, protecting the cloud from adversarial attacks of diverse types and intents, cannot be understated. Economic Denial of Sustainability (EDoS) attack is considered as one of the concerns that has stalled many organizations from migrating their operations and/or data to the cloud. This is …
Improving Energy Efficiency And Quality Of Service In An Integrated Wireless-Optical Broadband Access Network, Maha Shihab Ahmed
Improving Energy Efficiency And Quality Of Service In An Integrated Wireless-Optical Broadband Access Network, Maha Shihab Ahmed
Theses: Doctorates and Masters
Exponential growth in the volume of wireless data, boosted by the growing popularity of mobile devices such as smart phones and tablets, is forcing telecommunication industries to rethink network design, and focus on developing high capacity mobile broadband networks. Accordingly, researchers have undertaken developmental work for an integrated wireless-optical broadband access network (WOBAN). Passive optical networks (PONs) and fourth generation (4G) wireless networks are two major candidate technologies for the WOBAN. PON is a wired access technology, well-known for its high capacity, whereas 4G is a wireless broadband access technology, popular for its ease of deployment and ability to offer …

Free-Space 120 Gb/S Reconfigurable Card-To-Card Optical Wireless Interconnects With 16-Cap Modulation, Ke Wang, Ampalavanapillai Nirmalathas, Christina Lim, Efstratios Skafidas, Kamal Alameh
Research outputs 2014 to 2021
In this paper, we propose and experimentally demonstrate reconfigurable card-to-card optical wireless interconnects architecture with 16-Carrierless-Amplitude/Phase modulation. Results show that 3×40 Gb/s interconnection is achieved with 2 mW transmission power.
On The Effectiveness Of Intrusions Into Zigbee-Based Wireless Sensor Networks, Michael Johnstone, Jeremy Jarvis
On The Effectiveness Of Intrusions Into Zigbee-Based Wireless Sensor Networks, Michael Johnstone, Jeremy Jarvis
Research outputs 2012
Wireless Sensor Networks are becoming popular as a means of collecting data by military organisations, public utilities, motor vehicle manufacturers and security firms. Unfortunately, the devices on such networks are often insecure by default, which creates problems in terms of the confidentiality and integrity of data transmitted across such networks. This paper discusses attacks that were successful on a simple network consisting of nodes using the ZigBee protocol stack and proposes defences to thwart these attacks, thus leading to increased user confidence in the ability of organisations to provide secure and effective services. The outcomes were that it was possible …
Wi-Fi Security: Wireless With Confidence, Lucas Jacob, Damien Hutchinson, Jemal Abawajy
Wi-Fi Security: Wireless With Confidence, Lucas Jacob, Damien Hutchinson, Jemal Abawajy
Australian Security and Intelligence Conference
Since the IEEE ratification of the 802.11 standard in 1999, continuous exploits have been discovered compromising the confidentiality, integrity and availability of 802.11 networks. This paper describes the justification for a project to assess the security status of wireless network usage in society. It reviews the status of both commercial and residential approaches to wireless network security in three major Victorian cities, Melbourne, Geelong and Mornington, in Australia. By War Driving these suburbs, actual data was gathered to indicate the security status of wireless networks and give a representation of modern attitudes towards wireless security for the sample population. Preliminary …

Forensic Analysis Of The Contents Of Nokia Mobile Phones, B. Williamson, P. Apeldoorn, B. Cheam, M. Mcdonald
Australian Digital Forensics Conference
Acquiring information from a mobile phone is now an important issue in many criminal investigations. Mobile phones can contain large amounts of information which can be of use in an investigation. These include typical mobile device data including SMS, phone records and calendar and diary entries. As the difference between a PDA and a mobile phone is now blurred, the data that can reside on a mobile phone is somewhat endless. This report focuses on the performance of different mobile phone forensic software devices, and reports the findings. All aspects of the different software pieces will be reported, as well …

Engineering A Suburban Ad-Hoc Network, Mike Tyson, Ronald D. Pose, Carlo Kopp, Mohammad Rokonuzzaman, Muhammad Mahmudul Islam
Australian Information Warfare and Security Conference
Networks are growing in popularity, as wireless communication hardware, both fixed and mobile, becomes more common and affordable. The Monash Suburban Ad-Hoc Network (SAHN) project has devised a system that provides a highly secure and survivable ad-hoc network, capable of delivering broadband speeds to co-operating users within a fixed environment, such as a residential neighbourhood, or a campus. The SAHN can be used by residents within a community to exchange information, to share access to the Internet, providing last-mile access, or for local telephony and video conferencing. SAHN nodes are designed to be self-configuring and selfmanaging, relying on no experienced …

Bluetooth Software On Linux, Wireless Hand-Held Devices, Teck Khoon Low
Theses : Honours
In order to enable existing computers (non-Bluetooth ready) to connect to a Bluetooth piconet, a Bluetooth hardware device comprising of the Radio antenna, the baseband and control circuit is used. The digital portion of this device is also known as a Host Controller, HC. In the traditional communication lingo, the Bluetooth Hardware functions, as the Data Communication Equipment (DCE) while the Host is the Data terminal Equipment (DTE). This report discusses the theory and implementation of the communication protocol between the Host and the Host Controller, enabling communication between the computer and the Bluetooth hardware

An Adaptive Fuzzy Logic Controller For Intelligent Networking And Control, Irshad Nainar
An Adaptive Fuzzy Logic Controller For Intelligent Networking And Control, Irshad Nainar
Theses: Doctorates and Masters
In this thesis, we present a fuzzy logic control scheme to regulate the flow of traffic approaching a set of intersections. An adaptive Fuzzy Logic Traffic Controller (FLTC) is used to adjust the green phase split of the north-south and east-west approaches of a set of traffic signals based on the actual traffic approaching the intersection. Each intersection is coordinated with its neighbouring intersections by adjusting the offset of the local intersection. The offset is adjusted by a local fuzzy logic controller loacted at each intersection. A new fuzzy control scheme, using a supervisory Fuzzy Logic Controller, is also proposed …
