The cognitive radio network is an opportunistic spectrum access (OSA) network which consists of a primary system serving primary users (PUs) and a secondary system serving secondary users (SUs). There are N primary channels (PCs) licensed to PUs and M BCs dedicated to SUs. The PUs have strict priority over the SUs in utilizing PCs and the SUs first try to opportunistically access the PCs not occupied by the PUs temporarily. In case an SU is blocked from PCs, it then checks the BCs to find a free one. The system is modeled as a three-dimensional continuous-time Markov chain. We precisely specify the state-dependent transition rates due to imperfect sensing by simple recursive functions so that we are able to investigate the performance of the OSA system with imperfect sensing and BCs. Our results suggest that when the SUs opportunistically access the PCs alone with PUs operating in moderate or heavy loading conditions, the performance of SUs may be poor or unacceptable. By using some BCs to accommodate the SU calls blocked from PCs can significantly improve the performance.","PeriodicalId":425979,"journal":{"name":"2013 Seventh International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131494915","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}

One of the first applications will be smart cities. Cities are growing in population and citizens demand better services from the administration without increasing taxes. The only way to attend this demand is to improve information and how this is treated to take decisions. In other words, we should make the city smart. Smart cities are a novel concept that defines new technologies but also reuses some of the existing ones. All novel solutions phase the same problem: the lack of standards and widely accepted solutions. The City of Barcelona with the collaboration from research centers and industrial partners has been testing the smart city concept with the double purpose to contribute to the creation of standards and providing in the interim a solution to cope with the heterogeneity of providers, in particular from the wireless sensor part. This work has been structured as a \"Barcelona Intelligent City\" project or BCI. BCI project considers all the steps of the data process from its capture by a sensor network to the processing to make it relevant (pointing events that requires attention) and rich (with context information). Conclusions from the pilots has started to be applied. One example is the sensoring in civil works control. This paper includes some lines about Avinguda de l'Estatut Civil Works Project and its conclusions.","PeriodicalId":425979,"journal":{"name":"2013 Seventh International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"31 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131791673","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 balance loads among different communication interfaces in the hybrid cellular system is one of the most important issues that should be addressed for achieving efficient radio resource allocations. In a shared packet service, the 3GPP UMTS adopts the VSF-OFCDM interface to allocate orthogonal codes of an OVSF code tree in two-dimension (2D) spreading of the time and frequency domains. Nevertheless, UMTS suffers from high packet loss rate and high bandwidth waste rate. In 4G, although the LTE/LTE-Advanced interface offers a high data rate, it suffers from unbalanced loads and moderate reward. This paper thus proposes an adaptive radio interface selection for balancing loads between the UMTS and LTE/LTE-Advanced interfaces according to various interference and mobility environments. Numerical results indicate that the proposed approach outperforms other approaches in fairness, FRL and utilization.","PeriodicalId":425979,"journal":{"name":"2013 Seventh International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133251693","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}
