Therefore, it is a hot research topic about how to multicast datagram over satellites. Low Earth Orbit (LEO) satellites have short round-trip delay and low power consumption, it will be an essential part of future multimedia communication application. In this paper, we proposed a multicast routing for LEO satellite constellation networks with high performance. The algorithm uses the group members' geographic information to route multicast packets, with less memory, computer power and signaling overhead. Through simulation we evaluate the delay and performance of our algorithm.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"4 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114127865","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}

Modify registers (MRs) concern the offset difference of address code for offset assignment (OA) problems. Address registers (ARs) concern the assignment of program variables for general offset assignment (GOA) problems. This paper proposes a novel MRs and ARs assignment technique for SOA and GOA problems based on specialized DSPs Address Generation Units (AGU) machines. A technique to reduce the number of distinct offset difference so as to reduce the modify register assignment instructions was proposed for SOA and during GOA such that the cost is further reduced. An adjustable ARs assignment technique was proposed to reduce the GOA cost and the number of distinct offset difference during GOA. Our experiments show the reduction of the number of distinct offset difference during GOA can also help to improve the GOA cost.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126980777","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 achieve this goal, we collected landmark images all around the world, which were available on the web. For each landmark, we detected interest points and constructed their feature descriptors using SURF. Next, we performed a statistical analysis on the local features to select representative points among them. Intuitively, the representative points of an object are the interest points that best characterize the object. Similar representative points are merged for filtering and fast matching purposes. These points are indexed using an R-tree based on GPS information. Our scheme is based on client-server architecture. When the user takes a picture of a landmark using a mobile device, the client module on the mobile device extracts the local features from the image and sends them to the server, along with location and other sensor data. For the query, the server searches its index using the location data first to find nearby landmarks and then compares their local features. Matched landmark images are sent back to the client. We implemented a prototype system and performed various experiments. Through experiments, we showed that our scheme achieves reasonable performance.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128720624","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 wireless mesh networks (WMNs) where routers are generally static, the traffic carried by the backup paths may adversely impact other flows and the multicast group itself, because these paths increase the number of transmissions and thus the level of interference and congestion in the network. This impact, however, has not been examined, especially for multicast routing. We present simulation results that quantify the impact of data overhead of multicast multipath routing compared with single-path routing.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115650128","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 describes a proxy-based infrastructure that provides proxy services to support mobile device applications. Proxy services can be thought of as a library of functions where the functions execute on a proxy and serve as a bridge between client application on the mobile device and remote services. The infrastructure allows for a dynamic association of a proxy with a mobile device that takes into account the proximity between the mobile device and proxy and the mobility of the client mobile device. Furthermore, proxies are chosen dynamically and the services provided by a proxy are dynamically changing based on the requirements of the clients for a better resource utilization. Several experiments are carried out to evaluate the effectiveness of the proposed infrastructure. The results suggest that the services offered by the proxy can be used for quick recovery after disconnections with only the minimal addition of overhead.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121219564","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}

Authenticated media content is required to be transcoded at intermediate to accommodate heterogeneous applications. In this paper, an efficient stream authentication approach is proposed for scalable lossy media streams. At first, we describe a joint coding and stream authentication (JCSA) media transmission framework for flexible and secure transcoding. After that, we propose a generalized quality-optimized stream authentication (QOSA) model to achieve optimal end-to-end quality and minimize the authentication overhead. Furthermore, an implementation on the consultative committee for space data systems image data compression (CCSDS IDC) coder is realized by using graph-based and error-correction coding based (ECC-based) authentication. Experimental results demonstrate that the proposed scheme is able to provide high packet-loss robustness at the cost of a very low overhead.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129126272","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}

Context-aware access control mechanisms are an important prerequisite to protect sensitive data and services in secure ubiquitous computing environments. In an IT-supported workflow, process-related context constraints are a means to consider context information in access control decisions. A context constraint specifies that certain conditions must be fulfilled to permit the execution of a particular task. However, standard process modeling languages do not support the notion of context constraints in business processes. In this paper, we integrate context constraints with process-related role-based access control (RBAC) models and thereby support context-dependent task execution.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131572524","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}
