There has been much research and commercial work in recent years on applications using complex event processing systems. However, although there are several tens of descriptions of event processing use cases, those applications have been targeting very different domains and have been described only superficially or at incomparable levels of detail. We believe that the lack of a set of clearly described event processing use cases reduces clarity regarding the area, and reduces research and product acceptance. To counter this trend, the EPTS started a Use Cases WorkGroup (UCWG) on November 2007 with the goal of collecting, classifying, understanding, detailing, and disclosing event processing use cases. This tutorial will present the templates completed so far, and will provide very detailed descriptions of four event processing use cases as well as common trends and variations to those use cases seen in other use cases. Special emphasis is placed on challenging issues that push the state-of-the-art and real-life applications and issues.

The fast growth in wireless sensors and actuators have the potential to create a global computing infrastructure that is profoundly changing the way people live and work. People may interact with themselves, the physical world, and information services using a wide range of sensor devices connected together, enabling computing and communication at an unprecedented scale and density. This new wireless sensor infrastructure presents a number of challenges especially when it comes to data-intensive applications: enormous scale, different types of data, varying and intermittent connectivity, location dependence and context awareness, limited bandwidth and power capacity, small device size, and multimedia delivery across different networks.
Wireless sensor networks are now evolving from passive observation and reporting systems to active and reactive systems that dynamically evolve in response to complex and rapid spatio-temporal events. Upon the occurrence of events of interest, different network activities and functions start executing, transforming those simple events into meaningful and sophisticated events to an application. This processing chain includes localization, synchronization, information fusion, self-organization, power management, routing, filtering and correlation, query processing, privacy and security, data mining and knowledge discovery, etc. Furthermore, this processing chain should be based on event propagation models to accommodate the requirements of sensor applications.
Compared to event processing already existing on distributed systems available on the Internet, that designed for wireless sensor networks poses unseen challenges due to limitations in sensor storage, processing, and communication capacities. Adding to the aforementioned issues is the curse of dimensionality. In practice, due to their sophistication, sensor events are usually identified by more than one attribute. Management of multi-dimensional data is already a difficult problem in information systems. Doing so under the resource constraints of sensor networks is even much harder.
This tutorial aims at presenting a broad view of event processing in wireless sensor networks in the light of different contexts and backgrounds. The goal is to discuss the different network activities and functions that are related to event processing in wireless sensor networks.

Event Processing in Weather Responsive Scientific Workflow Cyberinfrastructure
Beth Plale, Jeff Cox, Chathura Herath, Scott Jensen, Yiming Sun - Department of Computer Science, Indiana University, USA (presenters)

Event processing in support of data-driven computational science research and education takes multiple forms. In our experience over the past 6 years in developing and supporting the National Science Foundation funded Linked Environments for Atmospheric Discovery (LEAD), we have reasoned over the benefits and use of events and event processing systems in multiple contexts. In this tutorial we propose to share the motivations, architectural considerations, research outcomes, and tools used in event processing in the LEAD science supporting cyberinfrastructure. We provide a hands-on experience with the production LEAD portal. We additionally discuss the number of individual tools that have emerged from the project that we support for use in other applications.

Beth Plale is Director of the Center for Data and Search Informatics, within the newly endowed Pervasive Technologies Institute at Indiana University.

Event Processing in Capital Markets
Richard Tibbetts - StreamBase Systems, USA (presenter)

Capital markets control the international flow of money and securities. These systems operate around the clock, processing huge volumes of transactions and information. Most of this volume can be modeled as events, and as a result capital markets is the focus of much innovation in Event Processing. Financial services also receive a lot of attention in the mainstream media, especially lately.
Despite these facts, the use of event processing in the capital markets is largely invisible to the academic community. Very little has been published by financial organizations, intent on preserving their competitive advantage. Information is generally passed by word of mouth, with systems changing faster than they can be documented. Recently though, researchers in event processing along with creators of commercial event processing platforms have begun to standardize the way in which systems are built. This knowledge transfer not only improves the software being used in capital markets; it is an opportunity for event processing researchers to learn from the practical experience of industry engineers.
The focus of this tutorial will be on areas where practices are standardized, rather than on the details that confer competitive advantage. We will start by reviewing capital markets' structure, understanding the participants and products. Then we will discuss information flows, both transactional and non-transactional, along with data formats and rates.
We will review messaging protocols and fault tolerance, particularly the FIX protocol and various market data transmission protocols. Decades of experience with multi-party distributed systems have built up a lot of interesting tools and systems, and we will identify opportunities for learning. Time permitting, we will also discuss the history and future of some of these protocols.
The bulk of the tutorial will be spent discussing applications for event processing within capital markets. These include market data analysis, order flow management, pricing, and monitoring. Particular attention will be paid to aspects of these systems that challenge the capabilities of current systems, or where approaches unfamiliar to the academic community are common. We will discuss not only Complex Event Processing/Event Processing Platform (CEP/EPP) implementations, but also other implementation techniques including distributed transactions, distributed memory fabrics, and publish/subscribe systems.
Researchers in event processing will learn about a new field of applications and challenges. Practitioners not familiar with capital markets will learn about implementation techniques from that field which may be applicable to their work. Attendees experienced in capital markets may also learn additional techniques or a new perspective.
