1. Security in wireless sensor networks

Wireless Sensor Networks (WSN) are expected to form an integral part of the foreseen ubiquity intelligent, future mobile network and are envisaged to play a key role in the vision of offering mobile, personalised services, in-home and out-doors, whenever and wherever needed. However, security and resilience across WSN, especially across insecure, heterogeneous and multi-administration domains like the augmented home environment, face essential limitations mainly stemming from their infrastructure-less operation and the limited node and network resources. Thus, the design of new protocols and architectures exploiting the available and emerging technologies is dictated. The proliferation of wireless sensor network applications also raises new challenges such as scalability.
The areas of interest for possible contributions include (but are not limited to):
Security architectures for next generation wireless networks
Secure routing
Trust models
Secure Service Discovery
Cross-layer security protocol design
Intrusion Detection Systems
Identity management and authentication
Key management
Original papers addressing either the protocol design aspect or the implementation technology aspect are encouraged.

2. RF Positioning Technologies

RF technologies, a hot research topic over the last decade, is a fast emerging technology in the market world growing at an average annual rate of 33%. A major component in RF applications are the RF positioning technologies on which this session is focused. More particularly, the session aims to bring together researchers from the academic and industry world and to be a discussion forum on the latest scientific and technological advances in RF positioning technologies as well as their research and commercial applications. Topics to be covered may include:
Two- and three- dimensional tracking
WiFi Asset Tracking and Tags
RF positioning in health care
RFID tags and applications
GPS positioning & applications
Positioning in sensor networks
Signal Processing and RF positioning

3. Computer Vision algorithms using Intelligent Agents

Software agents are computer programs capable of flexible, autonomous action and may support a wide range of different behaviours, defined as rules using for example machine learning algorithms such as neural networks. Agents also, generally, monitor their operating environment and respond to events in a timely fashion, utilising internal scheduling and planning engines to formulate a response.
In this special session, we present recent advances in the area of Artificial Agents Components with respect to several aspects of Image/Multimedia Processing including Computer Vision, Media Annotation, Content based Media retrieval techniques. In particular the first research papers present the recent innovative aspects for a) an on the fly media of multimedia content and b) a distributed metadata tracking algorithm oriented to improve the products supply chain. The other papers involve intelligent agents algorithms for a) evaluation planning combined with computer vision tools, b) for image and associated keywords retrieval, c) industrial planning and d) health monitoring.
As a result this special session will present the new advances in the area of intelligent agents with combined with computer vision tools and machine intelligence algorithms.

4. Synthetic Aperture Radar (SAR) Images Analysis

In recent years new achievements have been obtained in the field of SAR image analysis. Additionally new sensors with improved properties (i.e resolution, temporal revisit time, different polarizations, etc.) appeared (TerraSAR-X, CCOSMO-SkyMed, ALOS, RADARSAT-2, SAC-D). New algorithms adapted to the data of these new sensors were developed as well new applications became possible ranging from environmental applications, risk management and damage assessments to military applications. This special session calls for papers that present new research and application results of SAR image analysis in the domain of remote sensing. The papers should be related to the following topics, but are not limited to:
SAR and InSAR image analysis and applications
Multimode operation: multiangle, multipolarisation, multfrequency (multispectral) SAR and InSAR
SAR images and scene modeling
Inversion and information extraction algorithms: despeckling, superresolution and segmentation
Modeling and simulation of ocean waves
Application of SAR images to risk prevention and disaster management

5. Advances in Biomedical Signal and Image Processing

The proposed special session intends to focus on recent advances in the field of biomedical signal/image processing and bioinformatics which encompasses techniques for the acquisition, processing, classification, and analysis of digital biomedical information. High quality papers in all areas of processing biomedical signals, images, and related information, classification, and analysis of biomedical data, and decision support of clinical processes are solicited. Sample applications include: (1) digital imaging research utilizing modalities ranging from x-ray imaging, NMR and CT, to SPECT and PET, to optical microscopy, to combinations such as PET/NMR; (2) signal processing research utilizing modalities ranging from biomedical data like MRS to biomedical data retrieved from wireless sensors; (3) medical and imaging informatics research, including content-based image retrieval from databases and clinical information infrastructures and knowledge engineering and (3) bioinformatics research, such as correlation of clinical findings with genomic markers.
