Building structure information is necessary for the realization of indoor location information services (indoor LBSs). In indoor pedestrian networks and building structure information, since the shortest route calculation can be directly applied, the route from an arbitrary position to a destination can be obtained by a computer. Therefore, navigation and recommending a healthier route is possible by route recommendation. However, the generation of the indoor pedestrian network is costly, so it does not necessarily exist. Therefore, as a low-cost generation method, our final goal is to automatically generate an indoor pedestrian network structure by collecting the walking sensing data from many users and integrating the estimated 3-D walking trajectories. In the integration of such trajectories, such partial matching places as walking in the same passage are used as clues. To estimate a partially matched place, we use a stable zone (a stable walking zone) and linear walking. Since the stable walking zone detects the continuation of the state with only a slight change, the estimation accuracy becomes higher than the right and left turns. We estimate the correspondence among stable walking zones by machine learning using the walking time, the walking distance, the height, and Wi-Fi information. For machine learning, we use a support vector machine (SVM). From the results of an evaluation experiment with HASC-IPSC, an indoor walking sensing corpus, we obtained a result where the F value was 0.81.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"325 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132162043","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}

However, they often only support a single modelling approach and semantics, whereas distributed systems and networks often are a conglomeration of different technologies and functionalities. In this paper we propose a novel approach to model these systems and make them amenable to formal analysis. We enhance the ambient calculus with “wormholes” as a convenient way for ambients to travel between “worlds” representing the different technologies and functionalities by means of different semantic layers. Our approach enables easy and natural modelling and analysis of multi-layer systems for ubiquitous computing and networking.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139789","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}

Thus, it is difficult to obtain reliably accurate device authentication with RSS. An alternative is proximity authentication, in which an infrared camera recognizes the movement of a hand-held device. In this method, the camera cannot recognize device inclination, and the user needs to have a special camera. In this paper, we propose a method that performs authentication by pairing a PC having a common camera and a hand-held device having an accelerometer. In this method, the PC recognizes a marker on the display of the device and calculates the similarity between the displacement of the marker and the acceleration of the device. We performed experiments to determine how the similarity changes according to the distance from a device to a camera and whether an eavesdropper outside the camera range can perform pairing. As a result, we found that it is possible to set a threshold for the similarity, but the standard deviation of the similarity was large, making the method unstable.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"345 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127881410","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 that case, an enormous number of addresses are required, so IPv6 address is inevitable. Therefore, when a user communicates with a device assigned IPv6 address, it is common to use a user-friendly identifier such as fully qualified domain name (FQDN) instead of an IP address. However, the current IoT device often has no function of setting the FQDN in many cases. This paper proposes flexible name autoconfiguration (FNAC) which can automatically generate FQDN without altering specification of IoT device at all. In FNAC, FQDN is automatically generated based on device information that can be acquired using the communication protocol used in each IoT device, and this function is installed in a home gateway (HGW). Additionally, by setting the information such as the installation location of the IoT devices in the HGW, a user can include a label about the location in the FQDN, or change the FQDN to a more recognizable FQDN.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"73 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128047505","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}
