Overview of ISSNIP-Melbourne Node's Research

These few years have seen a tremendous amount of research activities in wireless sensor networks (WSNs). We see real interests coming from agriculture, several segments of the manufacturing industry and science. Here in the University of Melbourne, a node of ISSNIP, short for Intelligent Sensors, Sensor Networks and Information Processing, has been established with the mission of taking WSNs a step further by fusing it with other well-established scientific disciplines. Our initial goal is to add value to Australian businesses, in the areas of defence, heath-care and environment.

 

Our primary research interests include, but are not limited to, flow control, security, localisation, biomedical and environmental applications (Figure 1). We cover a few topics here to give you an idea of current activities.

Activities

Localization

A lot of applications require localization support. Although many schemes are already available, Alistair Shilton and Bharat Sundaram are getting promising results by applying techniques in Support Vector Regression, and have developed a new methodology called Complex Support Vector Regression to tackle the problem.

Biomedical Applications

 

Falls in the elderly Australian society cost the government at least 2 billion AUD annually. Rezaul Begg, Ahsan Habib Khandoker, Daniel Lai and Slaven Marusic are looking for a way to detect and estimate the probability (or risk) of a person falling. Currently, they are investigating the sensitivity of the minimum foot clearance (MFC) as a gait variable for classification using signal processing techniques together with SVM classification [1]. 

 

Environmental Applications

 

Marine biologists discovered that water temperature plays an important role in the disintegration of coral reefs. Stuart Kininmonth from the Australian Institute of Marine Science (AIMS), and Stefan Dulman and Supriyo Chatterjea from the University of Twente collaborated in developing sensor networks for monitoring water temperature at the Great Barrier Reef.

 

Flow Control

 

The principal researchers are Jiong Jin, Weihua Wang and Jinsheng Sun. Their main concern is the flow control and resource allocation problem for heterogeneous WSNs which consist of diverse sensor types and applications. Recently they have proposed a distributed algorithm for the transport layer that allocates bandwidth among sensor nodes so that certain performance guarantees are provided for sensor nodes [2].

 

Security

 

There is a lot of focus on security in the group, because security is a cross-layer concern in WSNs. As networks become more specialized, nodes become more low-cost and security becomes more critical, we envision and predict that some nodes of the network will be dedicated to security functions, especially in military applications. One such security function is intrusion detection and response. Sutharshan Rajasegarar, Chris Leckie and James Bezdek (foreign collaborator) have been using support vector machines (SVM) for anomaly detection [3]. Another security function, interestingly, on the attacker side, is energy-efficient link-layer jamming, where the bad guys use sensor-scale motes to launch distributed and energy-efficient jamming attacks. Researcher Yee Wei Law is gauging the practical impact of such attacks, by trying to predict link-layer traffic using machine intelligence.

 

On the more conventional front, Yee Wei Law is working on several areas. In key management, he is looking at the problem of k-connectivity of the pseudorandom key pre-distribution scheme. In information security, he is looking at the efficient implementation of asymmetric-key ciphers and protocols.

Past Activities

 

ISSNIP has organized numerous events since its existence. We will review the conferences, workshops, education-related events and seminars that have taken place last year (2006), to give you a taste of the active role played by ISSNIP.

 

Conferences

 

The First European Conference on Smart Sensing and Context (EuroSSC 2006) was held on 25th-27th October 2006 in Enschede, the Netherlands. The conference, chaired by Partner Investigator, Paul Havinga, sought to explore the underlying techniques, protocols, architectures and algorithms for smart surroundings with intelligent, networked and co-operating objects. The conference accepted 29 papers (at an acceptance rate of 27%), from researchers across Europe, Asia and North America, and was attended by approximately 100 researchers.  The success of the event and ISSNIP researcher involvement has prompted organisers to hold a symposium on the same area at the ISSNIP 2007 conference in Melbourne.

The Seventh ACM-IFIP-USENIX International Middleware Conference (Middleware 2006) was held on the 27th November 2006 to 1st December 2006 in Melbourne, Australia. The conference is the premier conference on middleware research and technology. The broad scope of the conference encompassed the design, implementation, deployment, and evaluation of distributed systems platforms and architectures for future computing environments.

 

More conferences will be covered in the next issue.

Workshops

The First International Workshop on Middleware for Sensor Networks (MIDSENS 2006) was held on the 28th November 2006 in Melbourne, Australia. The aim of this workshop was to stimulate research in the specific domain of middleware for WSNs, to collect current expertise, and to further refine and integrate different approaches.

 

The Workshop on Wireless Sensor Networks in Biomedicine was held on the 21st November 2006 in Sydney, Australia. This one-day workshop was targeted at researchers and practitioners of WSNs for biomedical applications. By bringing together experience in biomedical applications, and expertise in wireless devices and networking protocols, this workshop aimed to foster inter-disciplinary research collaborations.

 

The Fifth Ballarat Workshop on Global and Non-Smooth Optimization: Theory, Methods and Applications was held on the 28th-30th November 2006 in Ballarat, Australia. The workshop brought together experts from Australia, the Pacific region and around world in the area of optimization theory, methods and applications. The topics included different areas of optimization, optimal control and their applications, with an emphasis on theory, numerical methods and applications of global and non-smooth optimization. The workshop also incorporated a one-day focus meeting on global and non-smooth optimisation problems in data analysis and engineering. The workshop was also dedicated to the memory of Prof Alexander Rubinov.
