In this paper, we present several such applications. Graduate students in both these programs are taught to use innovation in their approach, to designing a new system or modifying an existing system. This approach is emphasized in a series of courses, which then culminates in their Masters Thesis or projects. One important component of this approach is that their concept should be implementable with the current available technologies or emerging technologies. This will enable them to think in more practical ways of implementing and marketing their product or process in the immediate future. Two of the systems presented here are based on RFID, and two systems are based on intelligent web services. The benefit of this approach is to create a new breed of workforce consisting of effective thinkers and innovators. It also teaches students that innovation is a never ending process - and that innovation can happen by looking at everyday systems in a different light, including application of new technologies to existing products, creating efficient processes, or creating new products.","PeriodicalId":281865,"journal":{"name":"2012 Computing, Communications and Applications Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125745909","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}

Kurose","doi":"10.1109/COMCOMAP.2012.6154002","DOIUrl":"https://doi.org/10.1109/COMCOMAP.2012.6154002","url":null,"abstract":"In recent years, social interest in viewing consumer-generated media (CGM) contents has been rapidly growing, so their network traffic has been increasing considerably. To cope with this new increase in network traffic, we propose a tag caching router (TCR) architecture that supports folksonomies-based search and content caching for CGM content. Folksonomies are key words or metadata attached to the associated content by CGM-content creators, providers, and viewers to characterize the CGM content. The falksonomies-based search helps a user to find his/her interesting content because it automatically collects from the network the information of candidate contents with the folksonomy specified by the user and presents it as a content list to the user. The TCR architecture caches both content lists for content search and the associated contents for content downloading. We call this enhanced caching method as content caching. The performance of the proposed caching architecture was evaluated by performing a simulation for a wide variety of CGM contents with different traffic characteristics. The simulation results indicate that under a network model with 5 × 5 mesh-topology TCRs, content caching enables the TCR architecture combined with a conventional URI-based search to support a maximum of six-times more CGM access requests due to content caching than the number of accesses that can be supported by a conventional TCP/IP-based end-to-end architecture with a URI-based search. The number of accesses supported by the TCR architecture combined with folksonomies-based search increases to 17-times the number of accesses supported by the conventional TCP/IP-based end-to-end architecture with a URI-based search.","PeriodicalId":281865,"journal":{"name":"2012 Computing, Communications and Applications Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128775001","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}

Most of researchers use NS-2 to evaluate their new protocols/architectures. Although NS-2 has much resource and many available tools to generate different characteristics and network scenarios, source codes created on NS-2 is not able to be reused for real implementation. The releasing of NS-3 changes the way researchers work. NS-3 allows the researchers to work on both simulations and emulations with the same implementation and source codes. These can help researchers to evaluate their works on a single computer for simulation or on a real system without wasting their time to implement their works twice; one in NS-2 simulation and the other in real system. In this paper, we elaborate different points of protocol implementation between NS-2 and NS-3. We recommend a setting for mobility trace in order to obtain correct results between NS-2 and NS-3. Then, as a case study, we use DECA, which is a reliable broadcasting protocol for VANETs and previously implemented on NS-2. How to transfer DECA from NS-2 to NS-3 and how to validate its performance are shown. Moreover, an emulation of DECA on real system using NS-3 is described. The emulation results show a problem caused by asymmetric links which is not concerned in most of literatures. In this paper, therefore, we also propose a simple solution to help protocols' operation in the asymmetric link scenarios. The simulation results show that our solution can improve protocol performance.","PeriodicalId":281865,"journal":{"name":"2012 Computing, Communications and Applications Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129684276","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}
