In this proposal, an agent that receives a request will use an AI-based planning algorithm to decompose the received request into several subtasks; it will handle those for which it has know-how and available resources; and it will use decentralized networks computing methods to delegate the rest of the request to other agents that can possibly handle it. These, in turn, will recursively apply the same process until the initial request is completely solved or until some specified termination condition holds. The work contributions to the state-of-the-art are: the creation of an AI-based planning algorithm capable of partial task decomposition with only partial knowledge of available planning operators; and the creation of a coordination infrastructure that enables agents to delegate subtasks to other agents in totally unstructured decentralized environments","PeriodicalId":328547,"journal":{"name":"First International Conference on Complex, Intelligent and Software Intensive Systems (CISIS'07)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115235286","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 groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carried out using only the resources of the group. This management is done in a completely decentralized manner, and the system is self-organized in the presence of component connections, disconnections and failures. We demonstrate its validity through the implementation of a prototype and the execution of some tests, which allow us to guarantee that the system is self-organized, always reaching a consistent state","PeriodicalId":328547,"journal":{"name":"First International Conference on Complex, Intelligent and Software Intensive Systems (CISIS'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129323821","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}

Various techniques have been proposed to cope with data congestion, such as data aggregation techniques, multi hop routing techniques and flow control techniques. Although these techniques help to avoid or control congestion, they do not address the issue of data persistency effectively. This paper presents an adaptive self configuring in-network storage model for data persistency in wireless sensor networks. The model is built on a clustered sensor field where we have utilized dense node deployment in the vicinity of the routing nodes to act as data buffers during congestion periods in order to avoid data loss. We show that the in-network storage model can be used in combination with congestion avoidance/control techniques to develop data persistent congestion avoidance/control strategies","PeriodicalId":328547,"journal":{"name":"First International Conference on Complex, Intelligent and Software Intensive Systems (CISIS'07)","volume":"6 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132236943","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}

It can integrate isochronous and nonisochronous services. Due to its medium access control protocol, the network has the unfairness of access for bursty traffic. This paper explores the effect of bursty lengths on the unfairness. In the simulations of the paper, the average delays of distributed and local queues of nodes are calculated for exhibiting the variation of unfairness corresponding to the alteration in the number of cells of bursty messages. The simulation shows that the unfairness is obviously affected by bursty lengths. As the number of cells increases, the unfairness of the delay of distributed queues will be more moderate. But the unfairness of the delay of local queues will become more severe. On the other hand, the throughput of the network is irrelevant to the bursty length","PeriodicalId":328547,"journal":{"name":"First International Conference on Complex, Intelligent and Software Intensive Systems (CISIS'07)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122991060","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}

The increasing functionality of this kind of network makes it necessary to propose tools and methodologies to facilitate software development. This paper proposes a middleware called MWSAN to provide a set of high level services for sensor and actor networks. The middleware meets the component-oriented paradigm and developers can configure it depending on the actor and sensor resources. It takes into account issues such as the network configuration, the quality of service (QoS) and the coordination among actors. MWSAN is specified in UM-RTCOM, a component model oriented to real time systems adapted to WSANs that allows us to take into account real time requirements in the applications. Additionally, we present an implementation model based on RT Java for actors.

However, by using conventional client/server model, the usability of co-operative works by users degreases and scalability in CVE cannot be attained as the number of the user increases. Also, in conventional CVE system, the presentation and interaction of 3D objects in CVE to users were simple, limited and did not consider the users background such as users interest and generation. Eventually the user satisfaction for CVE application was not necessarily enough. In order to overcome those difficulties, we introduce a new method which uses P2P overlay network to realize scalable CVE and recommendation system which uses user's interest to present and offer the proper objects in CVE. Using our suggested method, the 3D objects are distributed on the P2P overlay networks and their computing loads can be reduced, eventually the scalability of the CVE can be improved. Furthermore, by reflecting user interest information to the application system, user can access and communicate to 3D objects and contents in which he or she is more interested with higher priority. Thus, the total usability of the CVE system can be improved.
