The procedure consists of a preselection phase, in which the original dataset is reduced and the exhaustive search phase for the database records selected in the first phase. The maximum number of consecutive deletions represents the constraint. Besides eliminating the need for finer exhaustive search in the attack database records in which the detected subsequence is too distorted, the new search procedure also enables better control over the search process in the case of deliberate distortion of the attack strings. Experimental results obtained on the SNORT signature files show that the proposed method offers average search data set reduction in the typical cases of more than 70% compared to the method that uses the unconstrained edit distance.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128079608","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}

Consequently, there is a growing need for techniques to search these documents with information retrieval methods. Current XML search engines for P2P- networks lack the use of such methods. In this paper, a P2P search engine is proposed that applies an extension of the vector space model and exploits structural information to compute relevance of XML-documents, and thus can significantly improve retrieval performance. We describe how peers can perform a distributed query execution through cooperated retrieval and ranking of dynamic XML documents in a structured P2P-network based on a DHT-algorithm.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133039331","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 policy-based application-aware network QoS management architecture for grid environment. First, application QoS requirements can be caught by grid supporting middleware; they will then be decomposed by domain, translated into technique policies in policy engine, and enforced through real QoS guarantee mechanisms; finally, QoS monitor will collect network runtime information, monitor, report, and, if necessary, modify the policy translation process through a real-time feedback mechanism, so as to achieve adaptability and application-awareness of network QoS management.

Among these services, a representative example is a navigation service. Enabling such a mobile phone-based navigation service requires a technology of generating a buffered map which includes polygons, polylines and points within a specific distance along a route. This operation is called a buffered search operation which is a key component of navigation services for mobile devices which store no maps for navigation services in advance. Although traditional algorithms work well for other services such as GIS CAD and so on, they do not meet the efficiency requirements of a mobile phone- based navigation service. After revealing the strong performance shortcomings of the previous algorithm, we present a novel inverted index-based algorithm which is enabling mobile phone-based navigation services. The extensive experimental results demonstrate the significant performance improvement over the previous algorithm.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124793824","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}

Our LQ-CDS construction scheme can improve the network performance via two metrics: interference metric and bandwidth metric.

The SRS technique, however, has the problem of causing sharp noise, due to the extreme enhancement of the audible frequency band. This paper suggests a new 3D sound reproduction method that can address this problem. In order to prevent the audible frequency band from being over- enhanced, the algorithm suggested in this paper is designed to automatically restrict gain values calculated by the output ratio of the auditory filter designed after the human auditory system. From the results of computer simulations, it is confirmed that the suggested algorithm effectively prevents the audible frequency band from being over-enhanced, which is a problem of the conventional technique. In addition, it is verified in listening tests that the bass is evaluated to be comparatively inferior to the conventional SRS technique, while the clarity of sound was found to be superior.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130376238","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}

As sensor nodes are deployed in sensing field, they can help people to monitor and aggregate data. Researchers also try to find more efficient ways of utilizing limited energy of sensor node in order to give longer life time of WSNs. Therefore, how to reduce node's energy that is consumed in transmitting data has became a very important issue. From many kinds of paper, multi-hop routing protocol is well known for power saving in data gathering. Recently researches uses such types of the cluster-based (e.g., LEACH), the chain-based (e.g., PEGASIS) and the tree-based (e.g., TREEPSI) to establish their energy-efficient routing protocol. In this paper, we propose tree-clustered data gathering protocol (also called TCDGP) to improve the LEACH and TREEPSI. The novel proposed protocol can preserve both advantages and improve the power consumption further. Finally, simulation results show that our proposal has better performance than before.","PeriodicalId":254368,"journal":{"name":"Future Generation Communication and Networking (FGCN 2007)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129622022","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}

A series of interleavers can be generated by circular shifting a specific pseudo noise (PN) interleaver, which is generated by a PN sequence generator. Thus, the architecture of the proposed interleaver is much simpler than that of other interleaver schemes for IDMA systems.
