The model integrates object-oriented approach, multi-agent technique and Petri nets analysis method, so it embodies the object-oriented concepts including class, inheritance, encapsulation, and utilizes existed Petri nets analysis tools to ensure the design of the simulation system. Furthermore, we use Petri nets theory in agent structure design and analysis phases to make multi-agent simulation system developing efficiently. Compared with existed models, AGNTOM has some prominent features including asynchronous message-passing, better description for the frame of the system, better autonomous decision-making and self-adjustment abilities.","PeriodicalId":120577,"journal":{"name":"Proceedings Autonomous Decentralized Systems, 2005.

For such a network the physical layer must be able to provide a mechanism over DWDM to transmit and switch bit streams at very high speed, and to satisfy different users' QoS requirements. As a result, a novel switching technique called physical frame time-slot switching (PFTS) was developed at our lab. This paper is devoted to fast switching technique of burst and non-burst data in PFTS node. The improved format of the switching field of PFTS frame is discussed. Bursting phenomenon is analyzed and tactics in dealing with such feature is discussed in some detail. Relevant issues such as the structure of switching table and fast switching algorithm are proposed based on hardware design to satisfy QoS requirements with respect to transit delay, jitters and etc. at the physical layer.","PeriodicalId":120577,"journal":{"name":"Proceedings Autonomous Decentralized Systems, 2005.

In this paper, we present theoretically a high-level representation of temporary regional traffic states using Hasse graph and temporal change map under a grid-based site model. We first model the region within the monitoring range of the camera as an uncovered house and express it with a set of 4-tuples. Then we formulate a partial ordered relation with grid coordinates of the extracted objects in a specific site from which a Hasse graph is yielded. On the timeline, difference between two consecutive Hasse graphs makes a variable temporal change map. All temporary traffic states can be categorized into two types: one is the motion of a single object, represented simply with the Hasse graph of its location and the temporal change map; the other is the set of grouped patterns of all the extracted object, or the Hasse graph of the neighboring objects. With this representation and the fuzzy concept of neighborhood, key traffic states like collision and secure distance can be distinguished and determined using appropriate motion prediction based on the previous measurement to manipulate the undesirable cases on time.","PeriodicalId":120577,"journal":{"name":"Proceedings Autonomous Decentralized Systems, 2005.

Profiles are one of the major building blocks for making real personalisation happen. In the existing heterogeneous and upcoming pervasive computing environment typically numerous different profiles are used and maintained by the user or different services, devices or operators. In order to avoid multiple copies of the same data profile synchronisation and linking should be used and applied between the different locations and administrative domains, in which the different types of profiles reside. But keeping in mind the different contexts', in which these profiles have been constructed, it is mostly unknown how to match the meaning of one profile to another or how to harmonize the different kind of values in the different profiles. In this paper, mechanisms for efficient synchronisation of profiles based on semantic distinctions are introduced. By using ontology's to distinguish between semantic entities profiles can be kept synchronous even using low-bandwidth radio links and mobile devices like smart-phones and PDAs.","PeriodicalId":120577,"journal":{"name":"Proceedings Autonomous Decentralized Systems, 2005.

First, we describe the structure of the predator agents and the prey agent with their state sensing capability, the action learning method and the action choosing mechanism. Next we study two cooperative behavior mechanisms between agents of multi-agent systems in predator-prey problem. Finally, we demonstrate that cooperative agents outperform agents without cooperative behavior according to simulations of the predator-prey problem and display the corresponding experimental results.","PeriodicalId":120577,"journal":{"name":"Proceedings Autonomous Decentralized Systems, 2005.

It consists of simulation grid portal, simulation application oriented service middleware, grid middleware GOS and the simulation grid resources including various encapsulated simulation model services.

Though several ALM systems have been proposed, all the multicast functions have been independently developed and integrated into individual applications. In such a situation, the development includes a lot of redundancy. Our goal is to develop RelayCast, the middleware which provides the common functions of ALM to eliminate the redundancy. RelayCast has some functional units which support fundamental and minimum functions respectively, and realizes one complete ALM system by cooperation of the units. The functional unit contains several components with different algorithms, and RelayCast meets the requirements of various applications by choosing the appropriate component.
