The algorithm assumes registers are initially allocated based on linear scan algorithm. When there is a need to spill variables, either the allocated or the new variable is spilled based on the cost incurred in allocation. The cost is calculated as a function of number of definitions and uses of a variable for the rest of its live range. A mathematical model for determining the cost is proposed which decides register allocation. Given the live ranges of the variables the time complexity of the algorithm is derived. Simulations on an arbitrary program showed an improvement when compared to linear scan algorithm.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133880378","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}

During the channel allocation process, the delay-sensitive packets should have higher priority than other packets. Previously priority queue and Uplink State Flag Channel Allocation (USFCA) have been used to reduce the transmission delay of priority packets. In this paper, we study the performance of channel allocation for priority packet in the GPRS network with multi-slot capability. The results show that the transmission delay of priority packet can be further reduced by assigning multiple channels to priority packet in addition to the use of priority queue and USFCA.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131702273","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 proposed algorithm strives to maximize the network lifetime metric by distributing the source-to-sink traffic for a given routing request along a set of paths. Fuzzy membership function is used for designing the edge weight function. Simulation results obtained under a variety of network scenarios show that the proposed multipath scheme is able to achieve better lifetime results than those obtained by its predecessor single-path fuzzy routing scheme as well as by another well-known online routing scheme, namely the Online Maximum Lifetime heuristic.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125237618","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 first analysis the inner latency performance of the NoC infrastructure among routers, and we provide two modes to emulate the specific application on those infrastructures for the purpose of performance comparison. It is shown that NoC-based infrastructure performs better than bus-based one in terms of latency when the number of flits contained in the packets exceeds certain threshold. In addition, Spidernet-based infrastructure outperforms Mesh-based one under the same condition, which verifies the correctness of the theoretical performance analysis.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133673257","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 concept enables a huge increase in the complexity of e-commerce development. For example, various innovative business models have emerged from the largely spread-out technological concept, providing different values to customers as well as service providers. The objectives of the study are to explore and exploit Web 2.0 services in knowledge management for businesses. We adopt a KM perspective to explore the Web 2.0 challenges that service providers face in harnessing knowledge. More than one thousand sites of Web 2.0 applications were analyzed and classified and five types of business models were identified: exchanger, organizer, aggregator, collaborator, and liberator. These different types of Web 2.0 applications reveal the diversity of existing Web 2.0 applications as well as the risks and benefits associated with knowledge management of Web 2.0, and they provide a better understanding of the operating patterns and value propositions of the technology.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127811218","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 a conceptual design for removing phishing pages that have been uploaded on a website, potentially without knowledge of the website owner or host server. Initially the system is alerted to the presence of a phishing page upon receiving the Phisher’s solicitation e-mail. Next the system retrieves the location, IP address and contact information of the host server using a tracking program. Finally, the system sends notification to the Administrator about the phishing page on its server. It is then up to the host server Administrator to remove the phishing page from its server, or face the possibility of criminals continuing to use their site. This approach acts as the basis for further development into proactively (or aggressively) attacking Phishers directly, rather than being a reactionary approach that is common to most email filters and anti-virus software.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"37 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133733576","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}
