It aims to provide a convenient Cloud Service for Medical Imagery Grid applications. It extends our GIC architecture with an implementation of a light version of the Virtually-distribution Parallel Architecture and the Multi-level Services architecture that permit the deployment of distributed Grid applications onto our platform. We propose these architecture as solutions to achieve both the convenience of PaaS Cloud services and the richness of Grid applications. We show how we deploy a MAS segmentation algorithm for Medical Imagery onto our Acigna-G platform.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"386 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115912383","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 attempts have been made to create performance models for web servers. The paper describes modeling a Web server to be controlled by Feedback control scheme. Feedback command theory was initially used to control of industrial processes. Its use for the control of performance software is recent. It provides a number of mathematical tools which can be used to analyze the stability of the commanded system and find the best adjustment that responds to the performance criteria. Our approach proceeds in two steps: system identification and controller design. In system identification, we construct mathematical models of the target system in forms of discrete transfer function focused on single-input single-output (SISO) systems. The role of controller is to modify the transfer function of the target system with regard to the control error between the reference value and the output value","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124794200","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 the same time, many technologies have known a considerable success these few years. In one hand, the Web service technology is used to support interoperability but it is still not able to support the dynamism and the autonomy aspects. In the other hand, the agent technology is strongly recommended to support these aspects. In this paper, we propose a novel approach that combines these two technologies for a better interoperability of enterprises. Our approach includes a process that allows Web services, which represent the business functionalities of enterprises, to be discovered, invoked, and composed by agents representing these enterprises. The interoperability mechanism is based on the negotiation on these services. Our approach includes also an architecture supporting this process.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116703556","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}

However, the localization process is vulnerable to malicious attacks aimed at interrupting the functionality of location-aware applications. The wormhole attack is a particularly challenging one since the external adversary which acts in passive mode, does not need to compromise any nodes or have access to any cryptographic keys. In this paper, wormhole attack in DV-hop is discussed, and a Wormhole-free DV-hop Localization scheme (WFDV) is proposed to defend wormhole attack in proactive countermeasure. Using analysis and simulation, we show that our solution is effective in detecting and defending against wormhole attacks with a high detection rate.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117332960","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 this paper, we are interested to the validation phase in the process of requirements engineering in a cooperative context. The cooperation is not a recent practice because people cooperate since always. However, the cooperation, such as it reappears nowadays, is not simply a team work, it wants to be structured and organized in order to produce better results. To this purpose we propose a methodology which presents a collaborative approach of the requirements validation process based on the concepts of competences and multi-viewpoints. The objective of this methodology is twofold; first it increases the quality of the software product (i.e. it leads to better match users' needs) and it reduces the complexity of the validation task.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"209 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122431900","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}

Unfortunately, many parameters have to be tuned for any metaheuristic, and their values may have a great influence on the efficiency and effectiveness of the search. The exploration of an optimal combination of such values may be difficult and big time consuming. Clerc et al have defined a parameter-free algorithm for PSO (Particle Swarm Optimization), called TRIBES. In this paper, we propose to adapt TRIBES to solve discrete problems. To highlight our approach, we treat of the well-known NP-Hard Traveling Salesman Problem (TSP) problem. Modifications in different mechanisms and formulae adaptations are made, like in the generation process of the particles and in the displacement strategies. The experimentations results show the good behavior of the “Adapted TRIBES”. Comparison is made with a basic genetic algorithm, and with a branch and bound method.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117071094","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 this paper, we propose a solution based on the omega failures detector. The algorithm is highly adaptive with ad hoc networks in the sense that it can tolerate intermittent failures, such as link failures, sudden crash or recovery of mobile nodes, network partitions, and merging of connected network components associated with ad hoc networks. In addition, the algorithm reduces the number of exchanged messages to make it energy efficient. The paper also presents proofs of correctness to exhibit the fairness of this algorithm.","PeriodicalId":305060,"journal":{"name":"2011 10th International Symposium on Programming and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125456756","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}
