  • Considered by many authors as a technique for modelling stochastic, dynamic and discretely evolving systems, this technique has gained widespread acceptance among the practitioners who want to represent and improve complex systems. Since DES is a technique applied in incredibly different areas, this book reflects many different points of view about DES, thus, all authors describe how it is understood and applied within their context of work, providing an extensive understanding of what DES is.

  • A site plan is a map of the event and is essential for event planning and management. All key stakeholders can use it as part of the planning process, with consultation as to its final layout. The site plan must be easy to interpret and be posted strategically around the site for use by patrons. The site plan can be distributed for setting up the event and is also invaluable in an emergency. Use the checklist below to determine what must be shown on the site map. Use a simple grid format and include surrounding streets and landmarks. Entrances,...

  • Here we study the architecture and characteristics of the broker network. We are using a particular internal structure for the events (defined in XML but currently implemented as a Java object). We assume a sophisticated matching of publishers and subscribers defined as general topic objects (defined by an XML Schema that we have designed). However these are not the central issues to be discussed here.

  • In this section you should provide a general overview of your event and be as specific as possible about the activities you are proposing to conduct at the event. When selecting the dates for your event it is a good idea to check whether there are any other events already planned to avoid clashes in events. The timing of your event is also important to consider. Try not to plan your event during known quite periods when many people are out of town. Consider planning your event during the peak season to increase your...

  • The justification for choosing this typing scheme is scalability. In other sys- tems, such as one finds for example in the Java Distributed Event Specifica- tion [SunMicrosystems 1998] andCORBANotification Service [ObjectManage- ment Group 1998b], a notification is a value of some named, explicit notification type. This implies a global authority formanaging and verifying the type space, something which is clearly not feasible at an Internet scale. On the other hand, we define a restricted set of attribute types from which to construct (arbitrary) notifications.

  • There has been much previous work on node localization and event detection [6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16] , includ- ing foundational work on theoretical lower bounds [17, 18].

  • As an example, consider the case where several net- work packets arrive for a socket. We could consider each incoming packet as a discrete event, recording one event for each packet. However, the number of incoming pack- ets is essentially unbounded, while the amount of mem- ory in the system is finite; we would be unable to provide a guarantee that no events would be lost. The result of the above scenario is that multiple pack- ets are coalesced into a single event.

  • Analyzing future distributed real-time systems, automotive and avionic systems, is requiring compositional hard real-time analysis techniques. Well known established techniques as SymTA/S and the real-time calculus are candidates solving the mentioned problem. However both techniques use quite simple event models. SymTA/S is based on discrete events the real-time calculus on continuous functions. Such simple models has been choosen because of the computational complexity of the considered mathematical operations required for real-time analysis.

  • Probability and statistics are concerned with events which occur by chance. Examples include occurrence of accidents, errors of measurements, production of defective and nondefective items from a production line, and various games of chance, such as drawing a card from a well-mixed deck, flipping a coin, or throwing a symmetrical six-sided die. In each case we may have some knowledge of the likelihood of various possible results, but we cannot predict with any certainty the outcome of any particular trial....

  • Algorithms for Non-Product-Form Networks Although many algorithms are available for solving product-form queueing networks (see Chapters 8 and 9), most practical queueing problems lead to non-product-form networks. If the network is Markovian (or can be Markovized), automated generation and solution of the underlying CTMC via stochastic Petri nets (SPNs) is an option provided the number of states is fewer than a million. Instead of the costly alternative of a discrete-event simulation, approximate solution may be considered.

  • Simulation of Wireless Network Systems This chapter deals with simulation of wireless network systems. We introduce the basics of discrete-event simulation as it is the simulation technique that is used for simulating wireless networks. We then review the main characteristics of the commonly used stochastic distributions used for the simulation of wireless networks. The techniques used to generate and test random number sequences are investigated. Then, we introduce the techniques used to generate random variates followed by performance metrics considerations.

  • This paper presents a detailed case study of the Clickbot.A botnet. The botnet consisted of over 100,000 machines and ex- hibited some novel characteristics while also taking advantage of some characteristics of existing, well-known botnets. One of the most novel characteristics of the clickbot is that it was built to conduct a low-noise click fraud attack against syndicated search engines. This paper focuses on describing the novel aspects of the Clickbot.A botnet, and describes parts of our experience in in- vestigating it.
