But all features are not relevant and some of them are redundant and useless. In this paper, we propose and investigate a fast hybrid feature selection method - a fusion of Correlation-based Feature Selection, Support Vector Machine and Genetic Algorithm - to determine an optimal feature set. An appropriate feature set helps to build efficient decision model as well as reduced feature set lights up the training and testing process considerably. We have examined the feasibility of our approach by conducting several experiments using KDD 1999 CUP intrusion dataset. Experimental results indicate the reduction of training and testing time by an order of magnitude while maintaining the detection accuracy within tolerable range.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"83 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":"124365292","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 grid can provide abundant powerful computational resources with sharing and cooperation in grid environment. This paper gives an introduction to a collaborative processing mechanism based on workflow technology implemented in ImageGrid. The main idea is to encapsulate all parallel algorithms of remote-sensing image processing into grid services and recombine them with grid workflow to satisfy more and more complex remote-sensing image processing applications. In particular, we describe the architecture of the workflow-based grid system and the processing flow. We also give out the algorithm classification and an example of remote-sensing image processing grid application.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"32 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":"124489694","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}

This paper presents the testing results of channel properties of power line communications networks in China. According to the nature of distribution networks, office blocks and residential buildings are tested respectively. The testing results show that the main reason influencing the reliable communication of highspeed data of power line is the attenuation of the highfrequency signal, which exhibits more obviously in the branch of power line. For the multi-layer building, it is almost impossible to use the frequency range from 2MHz to 20MHz to realize the reliable communication from distribution transformer to each user, and it must be solved with the aid of such means as the repeater etc. Considering the signal’s attenuation, the lower frequency range is more suitable for the high-speed data communication of power line. So the frequency range of 2MHz-10MHz is suitable for the high-speed data access system of power line. For the question of attenuation, it can be solved with the aid of relaying technique.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"32 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":"115828603","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}

So, a coevolutionary model is presented based on genetic algorithm and ant colony algorithm, which runs one of the above two algorithm and exchanges another by estimating the state of their running. In order to search optimal result of problem, genetic algorithm and ant colony algorithm can run conjunctly in the model. Through the experimentation on symmetric and asymmetric TSP, the outcome shows that compared with other algorithm, the algorithm of the model takes a great improvement in the convergent speed, result optimization and also the avoidance of the precocity and stagnation.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"2 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":"132219351","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}

By exploiting dual channels, we can achieve a higher network throughput than using one channel, because dual transmissions can take place without interfering. The IEEE 802.11 standard allows for the use of multiple channels available at the physical layer, but its MAC protocol is designed only for a single channel. Our scheme establishes and utilizes two routes of maximally disjoint paths and distributes them into two different channels respectively. Even if only one of the two routes of the session is invalidated, the source uses the remaining valid route to deliver data packets in two channels alternately. The results of simulation show that our scheme has better network performance.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"14 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":"134422877","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 actual challenge is the load balance for tightly-coupled applications. In this paper, we focus on the important subclass of tightlycoupled applications, synchronous iterative applications and formally define their load balance problem. Two novel static meta heuristic algorithms are proposed for the load distribution: a genetic tabu hybrid search (GTHS) algorithm and a host clustering based iterative search (HCIS) algorithm, when different communication computation ratios are considered. To this end, the analysis and experiment results demonstrate the effectiveness of heuristic algorithms.","PeriodicalId":152233,"journal":{"name":"Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)","volume":"38 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":"134322377","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}
