In order to assure the load balancing and to optimize the resource utilization, a distributed system is using different software components, such as management tools, schedulers or monitoring tools. Considering the prediction of future behavior of distributed systems resources can offer better results in optimization and control. This paper proposes a state prediction algorithm based on neural networks using a genetic algorithm for initialization. The algorithm combines the advantages of the neural networks with the advantages of a dynamically constructed architecture and the very good results offered by a genetic algorithm. The prediction system includes the MonALISA monitoring system that collects information about the current status of the available resources in a distributed system. The algorithm is used in order to predict the next value or the next interval of values for parameters such as load, free memory or network bandwidth. The comparison between proposed algorithm and the classical prediction methods highlights the obtained improvements referring to the decreasing of the prediction errors.","PeriodicalId":265285,"journal":{"name":"2010 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123095203","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}

To solve the problem, Peer to Peer technology has been on the rise in content delivery systems. In addition, P4P system, which can tell a peer its adequate upload peers so as to reduce network traffic and to accelerate the content delivery speed, has been coming to the forefront. However, existing P4P systems have a problem that they cannot notify delivery routes minutely and accurately e.g. in units of routers or of peers. Therefore the hop counts between a download peer and an upload peer is not sufficiently reduced, then the network traffic is not satisfactorily decreased. For details, some existing P4P systems cannot satisfactorily reduce the hop counts, and the other existing P4P method which can reduce the hop counts has a restriction that IP addresses must be hierarchically assigned. To solve the problem, we propose a new P4P method reducing hop counts, which is free from the restriction. For this purpose, we use network structure information to search the hop counts, and utilize the hint server to manage the information. We evaluated the effect of our system by experiments in the lab. As a result, our method gives the best performance on the network traffic and the content delivery time among the existing methods. Additionally, we found that decreasing the hop count reduces the network traffic and the content delivery time. We researched the causes that the content delivery time is reduced by reduction of the hop counts. The most probable cause is the load balance of upload peers by decreasing the hop counts.","PeriodicalId":265285,"journal":{"name":"2010 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115592318","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}

Here, we extent our approach to account for regulators that consist of transcription factor dimers. The latter are frequently missed by module-finding tools since the expression profile of one of the dimers is typically un-altered while the profile of the second dimer changes significantly during the stress response. We identify two modules of stress-associated genes that are regulated by transcription factor dimers and show that ANN modeling can be used to accurately predict the expression of all genes in these modules. We also find that prediction accuracy is dependent on the specific stress category, in agreement with experimental studies where constitutively expressed transcription factors exert different regulatory actions upon different exposures to stressful stimuli. Overall, we show that TF dimerization is an important attribute of the transcriptional network regulation, which is frequently ignored by module finding tools, and can lead to the identification of important biological cascades whose regulatory action can be quantitatively simulated with ANNs.","PeriodicalId":265285,"journal":{"name":"2010 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122483813","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}

SMS messages are used in many different application fields, even in cases where security features, such as authentication and confidentiality between the communicators, must be ensured. Unfortunately, the SMS technology does not provide a built-in support for any security feature. This work presents SEESMS (Secure Extensible and Efficient SMS), a software framework written in Java which allows two peers to exchange encrypted and digitally signed SMS messages. The communication between peers is secured by using public-key cryptography. The key-exchange process is implemented by using a novel and simple security protocol which minimizes the number of SMS messages to use. SEESMS supports the encryption of a communication channel through the ECIES and the RSA algorithms. The identity validation of the contacts involved in the communication is implemented through the RSA, DSA and ECDSA signature schemes. SEESMS is able to certify the phone number of the peers using the framework. Additional cryptosystems can be coded and added to SEESMS as plug-ins. Special attention has been devoted to the implementation of an efficient framework in terms of energy consumption and execution time. This efficiency is obtained in two steps. First, all the cryptosystems available in the framework are implemented using mature and fully optimized cryptographic libraries. Second, an experimental analysis was conducted to determine which combination of cryptosystems and security parameters were able to provide a better trade-off in terms of speed/security and energy consumption. This experimental analysis has also been useful to expose some serious performance issues affecting the cryptographic libraries which are commonly used to implement security features on mobile devices.","PeriodicalId":265285,"journal":{"name":"2010 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122994405","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}
