Since the popularity distribution of queries follows a zipf-like distribution in a P2P network, the performance can get significant improvement if a simple and effective caching mechanism called hot spots caching mechanism (HSCM) is used, which stores the IP address and port number of the successor node of the key. Simulations also show that the HSCM is basically independent of particular P2P algorithms and can be easily combined with other improved methods to further improve the performance of P2P search capabilities.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125317658","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}

There are two major new features about the proposed scheme. Firstly, traditional Kalman filter needs measurement transformed. However, it is difficult and costly to be obtained. And our method could work without this message. Secondly, the traditional MUSIC algorithm would search the DOA of the targets through the whole plane, which is computational expensive. Our method would search the DOA of the targets only through some part of the whole plane. This leads to great savings in computational cost. Of the proposed algorithm, simulation results show that our method has similar accuracy to other method, but offers cheaper computational complexity.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121083844","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 conventional OCDMA system only allows finite units to transmit and access simultaneously according to the number of channels which be restricted by BER. To resolve this problem, a novel protocol based on slotted ALOHA is proposed in this paper. By using the reservation scheme and a distributed arbitration algorithm, channel collision and destination conflict can be avoided. The protocol can efficiently support the transmission of multimedia messages that require the different time-delay. The network throughput and average delay has been investigated by numerical analysis and simulation experiments. It is showed that the multipriority reservation protocol in this POF network is valid and efficient.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116486311","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}

For the cluster heads, we use tree¿s parent method for data structure, that is, we proposed an inter-cluster routing pool tree based on reversed spread way, and proved that as long as the cluster head¿s wireless communications radius is three times to the original one, it will be able to guarantee connectivity between cluster heads.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116343155","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}

However, nowadays traditional security tools like IDSs, firewalls etc cannot play the roles of effective defense mechanisms. Instead, they only generate elementary alerts to form alert flooding and they often have high false alerts rates. Moreover due to their weak collaboration-awareness, they cannot detect large distributed attacks such as a DDoS attack. In this paper, we present an efficient and effective model for collaborative alerts analyzing. Our system enhances the alert verification using assets¿ contextual information. By applying alert fusion and using a precisely defined knowledge base in the correlation phase, it also provides a method to get general and synthetic alerts from the large volume of elementary alerts. Moreover, this system is able to reconstruct the attack scenarios for multi-step attacks. Experiments show the system can effectively distinguish false positives, detect and predicate large-scale attacks in their early stage.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126717424","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}

Dynamically monitoring the state changes of an underlying system, detecting and reacting to changes without delay are crucial for the success of any access control enforcement mechanism. Thus, current systems or models should provide a flexible mechanism for enforcing RBAC with spatial characteristics in a seamless way, and adapt to policy or role structure changes in enterprises, which are indispensable to make RBAC with spatial characteristics usable in diverse domains. In this paper we will show how On-If-Then-Else authorization rules (or enhanced ECA rules) are used for enforcing RBAC with spatial characteristics in a seamless way. Large enterprises have hundreds of roles, which requires thousands of rules for providing access control, and generating these rules manually is error-prone and a cognitive-burden for non-computer specialists. Thus, in this paper, we will discuss briefly how these authorization rules can be automatically generated from high level specifications of enterprise access control policies.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126725906","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}
