Therefore, the design of protocols for those networks becomes a unique challenge. Routing in DTNs is one of the key components and remains open for discussion. In this paper we treat the routing for anycast delivery that is useful in situations where a host, applications or users wish to locate a host which supports a particular service. However, if several servers support the service, any of these servers can be used. Then we implement a routing algorithm using genetic algorithm (GA), because the route and destination decision influence many parameters simultaneously. Our simulation results have shown that the routing using GA performs better than the shortest path algorithm.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"2002 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131386752","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}

Through this, the users at different nodes can achieve the highest degree of collaboration. Some authors have already proposed file sharing and adaptation framework. As per their proposed framework, users are allowed to share adapted files among them, invoking their file sharing and adaptation service built on the top of advanced collaborating environment (ACE). For file adaptation, a hybrid approach has been mentioned for adapting files which considers users preferences as well as user's device capabilities. The goal of this adaptation approach is to provide the best possible adaptation scheme and convert the file according to the user's preferences and device capabilities. In this paper, we propose some new features for file sharing and adaptation framework to have faster and more efficient and meaningful collaboration among users in advanced collaborating environment. We are proposing a Key based registration system as well as an algorithm for key generation to automate the registration process for slave ACE nodes. We also propose an automated mechanism to distinguish trusted (registered) Slave ACE nodes, which are privileged for p2p file sharing under certain conditions. This approach will completely eliminate the manual intervention in the purposive node selection process. Moreover there would be a network traffic monitoring process which will radically reduce the network overhead to the master ACE node and introduce faster network collaboration in a distributive manner. Consequently, the approach leads towards better collaboration among the users of ACE.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127549503","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 prototype is domain-specific, the purpose of which is to map instructional text onto a knowledge domain. The context of the knowledge domain of the prototype is physics, specifically DC electrical circuits. During development, the prototype has been tested with a limited data set from the domain. The prototype now reached a stage where it needs to be evaluated with a representative linguistic data set called corpus. A corpus is a collection of text drawn from typical sources which can be used as a test data set to evaluate NLP systems. As there is no available corpus for the domain, we developed a representative corpus and annotated it with linguistic information. The evaluation of the prototype considers one of its two main components-lexical knowledge base. With the corpus, the evaluation enriches the lexical knowledge resources like vocabulary and grammar structure. This leads the prototype to parse a reasonable amount of sentences in the corpus.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129153582","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 analytical approach for the proposed topology is derived to explore the effect of crosstalk induced in multichannel WDM network due to OXC. The factors that affect the magnitude of crosstalk in the OXC are investigated and identified. The bit error rate (BER) performance of a WDM optical system is evaluated at a bit rate of 10 Gb/s on account of OXC-induced crosstalk and different noises. Power penalty is evaluated at BER of 10-9 shows that there is a significant impact of crosstalk on the number of wavelengths and input fibers.

Smart cards are gaining popularity in applications that require high security and store sensitive information. Modern smart cards, highly capable of complicated cryptology, provide a high assurance of tamper resistance and thus commonly used in payment application. Although advanced smart cards can not protect attackers from being defrauded by different side channel attacks. Small, embedded integrated circuits (ICs) such as smart cards are vulnerable to side-channel attacks (SCAs). We describe the development of differential power attacks and describe how to perform differential power kind of side-channel attack on an AES implementation, using simulated power traces. We also discusses the security prevention from such corresponding attacks, such as randomized masking techniques for software implementations.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132858553","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}

HS is derived by applying empirical mode decomposition (EMD), a newly developed data adaptive method for nonlinear and non-stationary signal analysis together with Hilbert transform. EMD represents any time domain signal as a sum of a finite number of bases called intrinsic mode functions (IMFs). The instantaneous frequency responses of the IMFs derived through Hilbert transform are arranged to obtain the TFR of the analyzing signal yielding the HS. A new frequency scaling method is introduced here for proper interpretation of the energy spectra in HS. The performance of HS is compared with well known and widely used short-time Fourier transform (STFT) technique for TFR. The experimental results show that HS based method performs better than STFT in time-frequency representation of the audio signals.","PeriodicalId":335795,"journal":{"name":"2008 11th International Conference on Computer and Information Technology","volume":"399 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132217458","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}
