The clustering of sensor nodes provides longer operational lifetime of the nodes and facilitates data aggregation.

The cluster heads of the clusters are elected based on the local energy levels of the nodes without involving any distributed messaging.

There are also a lot of approaches designed for outlier detection. We observe that, in many situations, clusters and outliers are concepts whose meanings are inseparable to each other, especially for those data sets with noise. Thus, it is necessary to treat clusters and outliers as concepts of the same importance in data analysis. In this paper, we present a cluster-outlier iterative detection algorithm, tending to detect the clusters and outliers in another perspective for noisy data sets. In this algorithm, clusters are detected and adjusted according to the intra-relationship within clusters and the inter-relationship between clusters and outliers, and vice versa. The adjustment and modification of the clusters and outliers are performed iteratively until a certain termination condition is reached. This data processing algorithm can be applied in many fields such as pattern recognition, data clustering and signal processing.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"63 1-3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132394413","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}

Recently, driven by the needs of large-capacity/high performance data backup, data de-duplication is becoming a new research focus of the storage industry. In this paper, we present a fingerprint-based backup method named FBBM which performs data de-duplication in the backup. FBBM breaks files into variable sized chunks using anchor-based chunking scheme for the purpose of duplication detection. Chunks are stored on a write-once RAID (Redundant Array of Inexpensive Disks) and indexed and addressed by the hash of their content, this leads to intrinsically single instance storage. FBBM outperforms traditional backup methods in terms of storage and bandwidth saving. This makes it a promising tool for modern enterprises to backup or archive their ever-growing valuable data with low storage and bandwidth cost.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127940395","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}

Transition from complete disconnectivity to low- cost, high-bandwidth connection can happen in a relatively short time span. Media consumption over such networks are influenced by two, contradictory user requirements. The first requirement is that the users would not like to see quality changes in the media stream. The second requirement is that the user would like to consume the media with the best available quality. This paper presents an adaptation algorithm that aims to reconcile these requirements. Architecture variants of the media adaptation problem and prototyping experiences are also presented.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114254103","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 work, we focus on processing images containing landmarks which are easily recognizable by human users. Our observations show that through the use of proper techniques for skyline extraction, the retrieval task of landmark images can be feasible. Specifically, after conducting edge detection on an image, an approach which works in the similar fashion as depth-first search is proposed to extract the corresponding skyline precisely. In addition to theoretical analysis of relevant issues, empirical studies show that our approach is advantageous to be utilized in practical applications due to its high efficiency, effectiveness and scalability.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131276742","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}

While P2P systems have already many existing and envisioned applications, the security issue of P2P systems is still worth deeply researching. Some traditional approaches mainly rely on cryptography to ensure data authentication and integrity. These approaches, however, only addressed part of the security issues in P2P systems. In this paper, we propose a trust management model for P2P file-sharing systems. We use the incomplete experience to get the trust rating in P2P systems, and use aggregation mechanism to indirectly combine and obtain other node's trust rating. Simulation results and analysis show that our proposed trust management model can quickly detect the misbehavior peers and limit the impacts of them in a P2P file-sharing system.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133116862","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}

Conventional file system which has been used for personal computers is the FAT and it is still adopted for most of current portable devices. The major problem of the FAT is overhead due to cluster switching which involves retrieving and updating of cluster connection information saved on the file allocation table. Because of this overhead, response time of file read and write operation cannot be guaranteed in the FAT. This paper proposes the NFAT which guarantees expected response time by reducing cluster switching overhead when it reads and writes data for portable multimedia devices. To verify our proposal, we have implemented a prototype NFAT file system on ARM9 development board and a Secure Digital Card. The experimental results show that the NFAT does not have irregular response time when performing read/write operations. Therefore, the NFAT is suitable file system for mobile devices which have real-time requirements in reading and writing multimedia data.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121889739","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}
