The specifications on the processing algorithms considered are: low complexity for a low power hardware-software implementation, high image compression for reducing wireless transmission power and bandwidth, acceptable image quality for video-surveillance applications under bad illumination conditions and in presence of noise in the wireless channel. The specifications have been defined for a possible implementation of the image wireless network over the low cost, low power but low rate Zibee wireless protocol.","PeriodicalId":319643,"journal":{"name":"2007 Fifth Workshop on Intelligent Solutions in Embedded Systems","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133499157","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}

Nowadays, the Open Service Gateway Initiative (OSGi) seems to be the only platform alternative supporting hot-plug of services and an easy way to deploy new ones which are capable to integrate heterogeneous devices into a common platform. But this platform can be managed by only one manager in a secure way, and this is limiting possible business models. The problem can be solved virtualizing the OSGi platform in such way that service providers can manage the RGW, and have full control over the services that they have installed, without conflicting with other service providers. This paper presents a general architecture for the virtualization of OSGi platforms that are running in a RGW.","PeriodicalId":319643,"journal":{"name":"2007 Fifth Workshop on Intelligent Solutions in Embedded Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126629675","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}

Whereas generating the application source code from such models no longer is uncommon thanks to the research of the last years, targeting a specific operating system with an application still is done by hand. This significantly restrains flexibility and reuse within the development of real-time systems, as often assumptions on the underlying operating system are hard-coded within the application. Consequently we come up with a compiler-based approach to automatically map real-time applications coded for a specific operating system to other operating systems offering different abstractions (e.g. time-triggered vs. event-triggered execution). This compiler-based approach is enabled by an operating system independent intermediate representation, which allows to flexibly combine different operating system specific front-and back-ends.","PeriodicalId":319643,"journal":{"name":"2007 Fifth Workshop on Intelligent Solutions in Embedded Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115211992","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}
