While monitoring mechanism could improve the availability to an extent, it may cost more resources and increase the response time perceived by end users. To decrease the overall usage of monitoring resources, this paper proposes to select some services bringing the highest availability improvement to the composition and allocate monitors on them while leaving others unmonitored. This paper first researched two common monitoring mechanisms in service composition and analyzed their different impact on the service composition QoS values. Then continuous-time Markov chain and discrete-time Markov chain were employed to build the availability model related to the monitoring rate or service pool size according to different kind of monitoring mechanisms. Based on these models, two algorithms were proposed, for two monitoring mechanisms respectively, to allocate monitors in the composition aiming at minimizing the overall number of monitors while making sure the composition availability could meet certain requirements. The monitor allocation algorithm could be used to get the overall number of monitors and those services to monitor in different scenarios. Empirical studies results showed that it was feasible to monitor only some services in the composition to meet certain availability requirement. Monitors allocation decreased the overall number of monitors in the service composition and also decreased the mean response time comparing with the scenario that all services were monitored.","PeriodicalId":203206,"journal":{"name":"2011 International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132661465","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 indoor environments the effective users' motion prediction system and wireless localization technology play an important role in all aspects of people's daily lives, including e.g. living assistant, navigation, emergency detection, surveillance/tracking of target-of-interest, evacuation purposes, and many other location-based services. Prediction techniques that are currently used do not consider the motivation behind the movement of mobile nodes and incur huge overheads to manage and manipulate the information required to make predictions. In this paper we propose an activity-based continuous-time Markov model to define and predict the human movement patterns. Then we demonstrate the utility of Nonparametric Belief Propagation (NBP) technique in particle filtering, for both estimating the node locations and representing location uncertainties, and for prediction of the areas that would be visited and those that would not in the future. NBP method admits a wide variety of statistical models, and can represent multi-modal uncertainty. This prediction system may be used as an additional input into intelligent building automation systems.","PeriodicalId":203206,"journal":{"name":"2011 International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129381887","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 general, on-demand video services enable clients to watch videos from beginning to the end in a pipeline fashion. As long as a client still caches the initial part of the video, it can provide on-demand service to the subsequent clients without intervention of a server. Therefore, the key challenge is how to maximize the availability of a video for stream relay by keeping the initial part of a video in a peer's buffer as long as possible. In addition, to address the issues of delivering data on lossy network and providing scalable quality of services for clients, the adoption of multiple description coding has been proven as a feasible resolution by much research work. In this paper, we propose a novel caching scheme for P2P on-demand streaming called Balanced Dynamic Buffering with multiple description coding. The proposed balanced dynamic buffering gradually reduce the number of buffered descriptions once the buffer gets full. In addition, peers are grouped based on the number of descriptions cached in its buffer. The intra-group balancing and inter-group balancing are applied for well distributing descriptions and balancing their forwarding bandwidth on peer-to-peer on-demand streaming network. Simulation results showed that the balanced dynamic buffering significantly outperformed other dynamic buffering schemes and the Coop Net.","PeriodicalId":203206,"journal":{"name":"2011 International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117126789","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}

Computational systems that store knowledge in many different ways have been built in order to emulate the capacity of human knowledge representation, taking into consideration the several inherent difficulties to it. Within this context, this paper proposes an experiment that utilizes two distinct ways of representing knowledge: symbolic, BDI in this case, and probabilistic, Bayesian Networks in this case. In order to develop a proof of concept of this proposal for knowledge representation, examples that will be built through agent oriented programming technology will be used. For that, implementation of a MultiAgent system was developed, extending the textit{Jason} framework through the implementation of a plug in called textit{COPA}. For the representation of probabilistic knowledge, a Bayesian Network building tool, also adapted to this system, was used. The case studies showed improvement in the management of uncertain knowledge in relation to the building approaches of classic BDI agents, i.e., that do not use probabilistic knowledge.","PeriodicalId":203206,"journal":{"name":"2011 International Conference on Complex, Intelligent, and Software Intensive Systems","volume":"123 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133986191","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}
