Area coverage is still an essential issue in a directional sensor network which consists of a number of directional sensors. In this paper, we study a novel \"area coverage by directional sensors\" problem. We propose the maximum directional area coverage (MDAC) problem to maximize covered area by scheduling the working directions of the sensors in the network. We prove the MDAC to be NP-complete and propose one distributed scheduling algorithm for the MDAC. Simulation results are also presented to demonstrate the performance of the proposed algorithm.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126843461","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 intuitive idea of using multiple unicasts to disseminate the message over the multicast overlay does not take advantage of the broadcast nature of radio transmission. In this paper, we propose to use stateless source routing to perform overlay multicast. By encoding the destinations and forwarders into the packet header, a member node only needs to transmit the packet through the radio once and those neighboring nodes specified in the header will relay the message. Through simulation, we compare our protocol with the differential destination multicast (DDM). The results show that our protocol improves energy efficiency and balances the energy consumption better.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134439631","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}

How to decrease the cost of network management becomes the new topic in IT industry. Autonomic computing is the key technique of grid computing, which can lower the cost of management effectively, whereas its implementation is very difficult. This paper takes the partition-able server as management object, on the basis of studying the autonomic computing and hardware features of partition-able server, a method based on policies is proposed to realize the autonomic computing system. After defining the policy type and action type, a series of measures are proposed to configure resources of servers, which achieves the self-management of system and lowers the management cost.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114399554","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 article, a fault-tolerance method that based on similar resources and related technologies are proposed and discussed. First, several mathematical models of key elements, such as computing nodes, similar nodes and tasks, are constructed. Then, the similarity computation methods and evaluation criteria are evinced by two different views: tasks and resources. Supported by theories above, numerous methods, such as similar nodes auto- discovery (SNAD) and its optimization one (oSNAD), redundant tasks auto-deployment, and reconfiguration policies of fault tasks and nodes are highlighted respectively. Simulation results show that these approaches and schemes can improve the adaptive fault-tolerance abilities of complicated embedded distributed systems.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"24 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128741711","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}

Followed by this tendency, many well-known e-learning specifications were proposed to regulate those digitalized learning activities in a standardized manner. However, with respect to the interoperability among various e-learning specifications nowadays, some of them were designed to support particular domains. And this will lead to the result of poor shareability of existing learning resources. On the other hand, the courseware authoring could be considered as the fundamental process while realizing an e-learning environment. As a result, the applicable scope and the user-friendliness should be taken into account for supporting efficient learning contents development.

Sensor nodes belonging to different sensor networks may not be able to collaborate properly to gain the capacity or performance due to inability to exchange information with each other. In this paper we propose a semantic-based query processing architecture that enables in-network processing of multiple sensor networks with unified protocol. In this architecture, there are low-level semantics in raw sensory data which are the mapping of the physical world. Semantics will be attached to the data to make the sensory data be understood more easily. In the process of matching, aggregated data are generated and semantics are attached to the aggregated data. The advantage of semantic-based architecture is that it can solve the problems in more complex situations. It makes the exchange of sensory data in multiple sensor networks possible and efficiently. The process of semantic creation and maintenance is described. We also introduce the concept of semantic data model. This infrastructure enables efficient information exchange and information extraction among multiple sensor networks.","PeriodicalId":367703,"journal":{"name":"2007 International Conference on Parallel Processing Workshops (ICPPW 2007)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123222254","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}
