It is important for students to operate network devices repeatedly to learn network skills. However, in practical learning with real network devices, students need a number of network devices. For this reason, it is not easy for students to prepare environment to be able to practice freely at any time. Therefore, we have developed a learning system to learn IP network skills on just one PC. Unlike existing network simulators, this system does not require students to learn scripting language to make scenarios. This system enables students to practice network skills freely and virtually on just one PC. We have implemented this system by applying the virtual Linux environment User Mode Linux. This system consists of virtual routers, virtual hosts, and operating functions. In this research, this system is primarily intended to practice operation of routing on virtual routers. To evaluate, this system was experimented. The results indicated that this system had sufficient performance for introductory network courses for undergraduate students.","PeriodicalId":236844,"journal":{"name":"Proceedings of 2011 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132271550","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}

With the recent advancements of Software Defined Radio (SDR) and Global Positioning Systems (GPS) with clocks having timers of 10 second precision, a method to three-dimensionally and continuously measure the Earth Atmosphere's refractive indices has been devised. The method is based upon the synchronous measurement of the time taken for a radio wave to travel from the source via the ionosphere to arrive at receivers place at known positions from the radio wave source. This method will allow us to measure small phase shifts between the receivers providing information on the propagation of the radio wave through the Earth's atmosphere, which is a function of the refractive indices within its multiple layers. Testing will help determine the full extent of the device's applicability. Although this device will measure locally, its placement at numerous locations could be used to help monitor the Earth's atmosphere over a large region and possibly globally, connected using current radio technology, enhancing our understanding of the magnitude and patterns of Earth's climate change.","PeriodicalId":236844,"journal":{"name":"Proceedings of 2011 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114690509","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}

Therefore, memory compression algorithm is proposed to solve the internal memory increment problem while maintaining the coding performance of IBDI. The memory compression methods have successively reduced the reference frame memory while preserving the coding efficiency by dividing a reference frame into the fixed size processing units and using additional information of each unit. However, additional information of each processing unit also has to be stored in internal frame memory; the amount of additional information could be a limitation of the effectiveness of memory compression scheme. Therefore, to relax this limitation of previous method, we propose a selective merging-based reference frame memory compression algorithm, dramatically reducing the amount of additional information. Simulation results show that the proposed algorithm provides much smaller overhead than that of the previous algorithm while keeping the coding efficiency of IBDI.","PeriodicalId":236844,"journal":{"name":"Proceedings of 2011 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127523338","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}
