Talk description: Security and trust are interdependent concepts which need to converge to address the cyber security needs of emerging systems. This talk will lay out a vision for this convergence. We argue that security and trust are inherently dependent on three foundational concepts: attributes, relations and provenance. Security researchers have dealt with these three concepts more or less independently. In the future convergence of these three is required to achieve meaningful cyber security. The talk will speculate on some research and technology challenges and opportunities in this respect.

Prof. Michal Wozniak, Wroclaw University, Warsaw, Poland
Talk description: The main aim of this talk is to deliver a either definite or compact knowledge on how hybridization can help improving the quality of computer classification systems. The talk is based on his recently published book on Hybrid classifiers: Method of Data, Knowledge, and Data Hybridization, Springer, 2014. In order to make readers clearly realize the knowledge of hybridization, this book primarily focuses on introducing the different levels of hybridization and illuminating what problems we will face with as dealing with such projects. In the first instance the data and knowledge incorporated in hybridization were the action points, and then a still growing up area of classifier systems known as combined classifiers was considered.

Talk description: Multi-antenna, or MIMO, technology has revolutionized wireless communication in terms of both power and spectral efficiency, and is now a part of commercial wireless standards (e.g., WiFi and cellular). MIMO techniques today, however, are fundamentally constrained by form factor and carrier wavelength, both of which limit the number of antennas that can be accommodated on a transceiver.
In recent years proposals have been made for distributed MIMO where groups of transceivers self-organize into virtual arrays that are indistinguishable in their functionality from a centralized antenna array and scale to an arbitrary number of nodes. Such distributed MIMO (DMIMO) concepts have been analyzed by theorists and dismissed by practitioners because of fundamental synchronization bottlenecks. Unlike centralized antennas, in distributed MIMO each node has its own oscillator. The frequency and phase of these oscillators undergo drift modeled by Brownian motion. Even expensive oscillators starting in perfect synchrony, become virtually incoherent within tens of milliseconds.
This talk will focus on synchronization issues involving two basic building blocks of DMIMO: distributed beamforming and distributed nullforming. In the former N-nodes collaborate to achieve a coherent beam whose power is N2-fold (as opposed to N-fold) higher than that due to a single node. Incoherence only results in an N-fold increase. In nullforming, nodes achieve a null at a prescribed location. It assists in achieving spatial-multiplexing and also secure communication. The key ingredient is scalable feedback by cooperating receivers.

Talk description: Cyber Physical Systems (CPS) are around for several years now. Market forecasts predict their broad utilization in the Internet of Things (IoT), as they promise cost reduction or an added value through the increase of services and quality and the availability of information. But, are CPS already well prepared for large-scale implementation in real life?
Mission critical points are scalability, energy-efficiency, safety and security. However, also cost issues in the development, the commissioning and the operation phases play an important role. This talk gives an overview on the state of the art in CPS and shows some selected examples from the extensive list of R&D projects in the author's team in the last 15 years. It will also give hints for further R&D opportunities.

Talk description: The data gathering capabilities of wireless sensor networks (WSNs) are particularly attractive for mission critical operations that can be deployed in unattended and hostile environments such as battlefield surveillance, military reconnaissance and emergency response; so intelligence can be gathered without the risk of human casualties. Traditional approaches for information discovery in WSNs have assumed the communication pattern as many-to-one where sensors gather information and then push to a central data repository, the “sink”. However, mission critical applications on WSNs are intended to work without a main control centre (such as a sink) and they demand life/time critical information and support for unique traffic patterns that maximize the network lifetime. Further, the nature of such mission-critical applications requires high quality of service (QoS) requirements for the information discovery process. Many emerging applications for WSNs require dissemination of information to interested clients within the network and require support for differing traffic patterns. These requirements make information discovery a challenging task because the complexity and energy-constraints of wireless sensors makes this a non-trivial problem. Early approaches to information discovery, such as flooding and gossiping with push-pull strategies use broadcast communication. For instance, in a military application, a sensor network might be deployed for enhancing the soldiers’ awareness when visibility is low. Sensors that detect an event can “push” this information out to every sensor in the network (e.g., sensors detect tanks and enemies and can periodically “push” that information to the other sensors on the network) or they can wait and allow a sensor to “pull” this information through querying (e.g., soldier sends a query such as “Where are the tanks or enemies?”). The efficiency of “push” or “pull” methods varies and depends on the demand for information. However, when the frequency of events and queries are not taken into consideration, pure pull-based or push-based methods are inefficient in real deployments. Recent approaches for information discovery, such as Comb-Needle, Double Ruling and Cross Roads, aim to successfully balance push and pull approaches to improve the QoS in terms of efficiency and lifetime of the WSN.
In this talk we will look at the challenges of information discovery in a multi-dimensional wireless sensor network. A multi-dimensional WSN is defined as a WSN that is deployed to gather and store data related to multiple attributes.
