Reusability helps in reducing time and cost of the development of a simulation process. Composing predefined components such as BOMs is a well known approach to achieve reusability. However, there is a need for a matching mechanism to identify whether a set of components are composable or not. Although BOM provides good model representation, it lacks capability to express semantic and behavioral matching.In this paper we propose an approach for matching behavior of BOM components by matching their statemachines. Our proposed process includes a static and a dynamic matching phase. In the static matching phase, we apply a set of rules to validate the structure of statemachines. In the dynamic matching phase, we execute the statemachines together at an abstract level on our proposed execution framework. We have developed this framework using the State Chart Extensible Markup Language (SCXML), which is a W3C compliant standard. If the execution terminates successfully (i.e. reaches specified final states) we conclude that there is a positive match and the behavior of these BOMs is composable. We describe the matching process and the implementation of our runtime environment in detail and present a case study as proof of concept.","PeriodicalId":225513,"journal":{"name":"2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114290755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These communities are working together to make these environments more sociable and interesting while introducing novel applications. A number of technical infrastructures are currently hosting these environments, however, Client Multi Server (CMS) infrastructures are considered best for their flexibility. Scalability and consistency are basic issues in developing large scale Distributed Virtual Environments (DVEs) that require special attention. The existing mechanisms have major performance issues, and therefore, more sophisticated infrastructures are required to deal with dynamic requirements of the applications. In this paper, we propose a novel Joint Hierarchical Nodes based User Management (JoHNUM) infrastructure for the development of scalable and consistent virtual worlds. It is compared with the game middleware, Matrix, for evaluation purposes that has demonstrated better performance over the existing static mechanisms. Simulation results show that JoHNUM achieves lower levels Resource Management Tree (RMT) and increases user interactive experience. Moreover, it uses fewer resources and minimizes communication overhead, almost the same as Matrix.","PeriodicalId":225513,"journal":{"name":"2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115380954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the environment can be dark or smoky, not allowing visibility to even a single exit. In such a situation, given that each individual in the crowd is accompanied with a helping device globally connected with a central server, a 'directional guidance' towards an optimal exit is a real possibility. In this context, the 'occupant density' around exits (within a static ‘exit area’) has been used in conjunction with the corresponding distances to devise a probabilistic strategy for optimal exit suggestion [1]. In this paper, we related the exit area with the level of visibility of the environment (the more the visibility, the more the exit area and vice versa). In this way, a more realistic human-behavioral model is implemented in which an individual viewing (seeing) an exit would always direct towards that exit, irrespective of the directional guidance provided. When an individual is not at any of the exit areas (not viewing even a single exit), a directional guidance is provided assuming that the individual is adhering to it. Additionally we used the measure of 'effective throughput' instead of occupant density, in conjunction with the corresponding distances. Through simulation results, we found a marked improvement in the evacuation time, when effective throughput was modeled instead of occupant density.","PeriodicalId":225513,"journal":{"name":"2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115577358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a clustering technique for MANETs, which is distributed, dominating set based, weighted and adaptive to changes in the topology called Distributed Scenario-based Clustering Algorithm for Mobile ad hoc networks (DSCAM). The election of clusterheads and gateway nodes is based on (k, r) − Dominating set, where k s the minimum number of clusterheads per node in the network and r is the maximum number of hops between a node and its clusterhead. After selecting clusterheads, affiliation of other nodes with the clusterhead is decided based on the quality of clusterhead, which is a function of connectivity, stability, residual battery power and transmission rate. Among the k dominating nodes, non clusterhead nodes select the most qualified node as its clusterhead. DSCAM creates stable clusters with less overhead and maximizes the life span of the network. The performance of this algorithm is evaluated through simulation and the results are encouraging.","PeriodicalId":225513,"journal":{"name":"2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132896517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several techniques have been proposed to develop scalable synchronization strategies, communication services or fundamental algorithms, while little has been seen to deal with the modeling stage of the application. Learning from the HPC (High Performance Computing) lesson, it is clear that the time spent in developing a simulation application must be considered in evaluating the scalability of the application. There are many discrete event simulation platforms built for large parallel and distributed simulations, such as SPEEDES (Synchronous Parallel Environment for Emulation and Discrete Event Simulation), GTW (Georgia tech Time Warp), and YHSUPE, etc. They take Event-Scheduling as their modeling paradigm and have achieved great runtime performance, but lack in providing efficient modeling methods. To deal with this issue, a component-based specification, which can support hierarchical decomposition of large models and facilitate model reuse, is presented. This paper extends the DEVS (Discrete Event simulation specification) and proposes a component-based formalism, called EDEVS (Event-Scheduling Discrete Event simulation Specification) for the existing Event-Scheduling parallel and distributed simulation platforms.","PeriodicalId":225513,"journal":{"name":"2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116147721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
