In this paper, a coverage and energy efficient (CEE) task assigning strategy is presented. The basic idea of CEE is to assign tasks according to node’s coverage degree and remaining energy. Based on this idea, grid-based coverage and energy efficient (GCEE) information gathering protocol is designed. GCEE is simulated with NS-2. How the various parameters affect the fraction of the survived nodes and the area energy balancing of the network is shown in simulation results.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123194788","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}

Based on the model and data structure a decision algorithm of data dependence of workflow is proposed, and the complexity of the algorithm is analyzed. The basic idea of the algorithm is to suppose if a workflow can be dealt with normally ( i.e. conform to data dependence ), then there must be a state in the reachable states of DataFlow in which a mark will appear in the postposition place of data transition. Lastly, by a computing example the decision algorithm of dynamic workflow based on Petri-Net is proved to be practical, effective and feasible.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121810041","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}

We perform some experiments on three clusters with different CPU and network performance in order to make clear what kinds of acceleration techniques and computing environments provide higher performance. The results show that a cluster with Gigabit Ethernet (GbE) network is the most cost effective solution that reduces registration time from ten hours to ten minutes with a linear speedup.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122520029","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}

Although topology control algorithms can optimize the network topology, the resultant topology is usually changeable. In this paper, we focus on how to maintain the network connectivity while reducing the maintenance overhead as some nodes fail. A distributed topology maintenance algorithm based on the shortest path tree is proposed. In this algorithm, nodes in immediate surroundings of a faulty node are first triggered to respond, and if they couldn’t ensure that the network is connected, the other related nodes are further triggered. Simulation results show that the proposed scheme can efficiently maintain the network connectivity with significant reduction in the overhead for topology maintenance.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131195377","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}
