It is proved to have great potential in lots of domains, e.g. intelligence traffic system, urban analysis, public safety etc. However, due to variety of data collection mechanisms, the data characteristics are various and need to be abstracted. In this paper, we outline the mobility data collection approaches and identify the differentiation in data characteristics and data process requirements. Then we propose an extendable framework which provides general data abstraction and universal data process flow for various mobility data. The experiment results are also presented to prove the framework.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114597437","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 paper, we study the probability of successful transmission by using the Poisson model with SIR based power control. Taking direct sequence scheme with binary phase shift keying for example, the expression to the probability of packet success is derived. For the exact expression to the probability of packet success can not be obtained, we provide the asymptotic expression. Finally, the performance of probability of packet success and the accuracy of asymptotic expression are studied by using simulation and numerical results.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123505241","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}

This paper addresses the architectural and fundamental design issues for supporting P2P streaming applications based on IPv4 and IPv6 coexist network environment. Our motivation is P2P streaming systems can be designed and implemented through a layered model and different layers in this novel model can implement different kinds of important functions. Our main focuses include the future P2P streaming applications design and their essential demands.

In order to relieve such limitations, in this paper, we propose an improvement over the former blind flooding approach by using a scheme based on the mobility of nodes (MON). In MON scheme, we categorize mobile hosts into active nodes and inactive nodes according to their relative high or low mobility. Inactive nodes forward packets for other nodes while active nodes do not. In simulation, we approve the advantages of our approach in most cases by comparing it with AODV in terms of several metrics. Finally, the advantages and disadvantages of MON are concretely analyzed in theory.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129562057","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}

Many standardization organizations such as ITU-T and ETSI are working on standardizing the Next Generation IPTV system. Basically, two different approaches have been defined for Next Generation IPTV system, namely IMS-based solution which reuses the IMS core components as its service controller, and non-IMS approach which has its own service control subsystem known as black box. This paper follows the IMS-based approach and presents a testbed including the basic components of the IMS-based IPTV, which can be used to simulate the real communication environment and test the performances of the IMS-based IPTV system. The IMS registration delay and IPTV call setup time obtained from the testbed are provided, and a novel queuing model for basic IMS-based IPTV system which is verified by the results of our testbed is shown in this paper.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126502492","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}

Video similarity search for content-based video retrieval is important in web service and research field. There is still no satisfying search method for scalable fast similarity search in large video database. In order to solve two challenging problems: video similarity measure and fast search method in large database, a novel efficient video similarity search strategy for video-on-demand systems is proposed in this paper. A compact video signature was computed according to image histogram and spatial-temporal features of video. The video similarity is measured by the computation of the distance of video signature. For the scalable computing requirement, a new search method based on Clustering Index Table was presented by index clustering. The experimental results from the query tests in large database show this method is highly efficient and effective for similar video search.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121566071","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}

TCP/IP is an open architecture, and its design principle only focuses on the efficiency of information transmission, while it does not consider the security issues. IPsec VPN has been proposed to solve the core network security issue. However, it is believed that the current use of IP addresses to denote both the location and the identity of a host is seen as the source of many Internet problems. Address-split-mapping network cleanly separates location from identity of host, and divides Internet into the backbone network and access network. This mechanism helps to solve the Internet problems such as security, mobility, multihoming, etc. Based our previous research work on Address-Split-Mapping mechanism, this paper describes the design, implementation and experiment results of IPsec-VPN based on Address-split-mapping.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122981844","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}
