Additionally, a novel session model is presented as an adapted version of the proposed mobility model. Furthermore, we develop an analytical framework using this session model to obtain several salient performance metrics such as network utilization times and handoff rates. Simulation results demonstrate that the proposed mobility model is substantially more accurate than existing modeling techniques, and that the proposed analytical framework provide tractable performance evaluation based on the new mobility model.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133293606","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}

Associating some semantics with 3D contents becomes a major issue specially for reusing such contents or pieces of content after having extracted them from existing 3D scenes. In this paper, we address this issue by proposing a generic semantic annotation model for 3D, called 3DSEAM (3D semantics annotation model). 3DSEAM aims at indexing 3D contents considering visual, geometric and semantic aspects. 3DSEAM is instantiated using MPEG 7 that we have extended with 3D specific locators. These locators link some visual, geometric and semantic features to the corresponding X3D fragments. These features can then be used for indexing and querying.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133642606","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, the solutions are still not satisfactory. The proposed process is divided into two levels: the former extends one of previous works in the domain to carry out a richer analysis of chord grids and is where the very analysis is performed, and the latter is devoted to correct some conceptual inconsistencies concerning enharmonic spelling of chords. Both levels use an engine to make inferences on some rule bases, which can be easily improved by addition of new rules.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128865390","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, there still remain challenging problems in this type of communications, especially their security over ad-hoc wireless channels. In this paper we present an approach to using a visual code system in order to establish secure spontaneous communications among wireless devices in pervasive computing environments. After briefly discussing the visual code system, we describe two distinct models of spontaneous communications, and then discuss how the visual code system can be leveraged in order to secure spontaneous communications in those models. We also demonstrate our approach through a proof-of-concept implementation.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131316671","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 limited capacity of the Internet hosts and the heterogeneous property of their access links are the main challenges of the peer-to-peer video multicasting over the Internet. Although, the rate-optimized overlay tree construction is a NP-hard problem, we propose a number of distributed and efficient protocols for rate-efficient overlay tree construction. Our proposed protocols include efficient join, improvement, overlay tree refinement and an optimum rate allocation protocol. The simulation results show the efficiency of the proposed protocols in rate-efficient overlay tree construction. We show that through combination of the efficient join protocol, tree refinement operations and an optimum rate allocation algorithm we can achieve a suboptimum overlay tree.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115456523","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}

As an extension of the Unified Modeling Language (UML) our language allows the platform-independent behaviour description and can be easily integrated into UML tools.

In this paper, we propose a complexity-aware live streaming system with bit rate adjustment that can handle the allocation of bandwidth and computational resource of a live streaming server. The proposed system encodes the input videos at different quality levels based on the priority of the input videos and the available computational resource. It incorporates a bit rate adjustment mechanism to compensate for the video quality drop resulted from the quality level change of high priority encoders. The resulting system is able to handle channels more efficiently because the complexity of high priority encoders can also be dynamically adjusted with little quality drop. A new complexity adjustment method is developed that enables the system to stabilize more quickly and minimizes the variance of the time buffer. The experimental results show that the system can handle more channels while still maintaining the quality of high priority encoders. The proposed system is applicable to multimedia home gateways, surveillance, IP-based TV, and on-line sports game relays.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128209969","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}
