Accordingly, there are various IoT devices. There is an extremely wide variety of data from IoT devices such as images, and sounds. It will become possible to construct a heterogeneous remote monitoring IoT system using various valuations of IoT devices. However, a heterogeneous remote monitoring IoT system cannot send data in completely because almost all mobile network services for the IoT system do not guarantee bandwidth. In this paper, we propose a priority control mechanism for a heterogeneous remote monitoring IoT system. The proposed mechanism enables a best-effort IoT system that guarantees only the minimum necessary data telecommunications. The proposed mechanism controls the priority by using application requirements. We implemented the proposed mechanism and evaluated its effectiveness with a sending ratio and average delay time of each priority. The sending ratio results of each priority increased to 29.2% in daytime. The average delay time results of each priority decreased by up to 96.0% in nighttime.","PeriodicalId":406787,"journal":{"name":"Adjunct Proceedings of the 13th International Conference on Mobile and Ubiquitous Systems: Computing Networking and Services","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132372042","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 order to efficiently power sensor nodes from UAVs using wireless power transfer, an appropriate UAV navigation algorithm is necessary. UAVs can locate a certain sensor roughly, but they cannot find the exact location. In our proposed method, a UAV draws circles using each point as a center and each distance as a radius. Then, it counts the number of intersections of the circles and quickly approximates the exact location of the sensor with the densest intersections as a near-optimal point. There have been several studies of battery-less wireless sensor networks (WSNs) for agricultural sensing, and some recent studies have used optimal tracking methods for UAVs to wirelessly power sensor nodes. However, these proposed systems were designed without considering the time needed to complete the wireless power transfer to each node. Because a UAV's battery capacity is limited, the area coverable by a UAV is determined by the amount of time needed to power all the sensor nodes in the field. Thus, if a navigation algorithm can enable UAVs to reach the near-optimal point more quickly, fewer flight tasks will be needed to cover the fields, which will reduce system operating costs. We compared our proposed method to a conventional hill-climbing algorithm in terms of navigation accuracy and time needed to power the sensor nodes. The results showed that the proposed algorithm performed 30% better than the conventional algorithm.","PeriodicalId":406787,"journal":{"name":"Adjunct Proceedings of the 13th International Conference on Mobile and Ubiquitous Systems: Computing Networking and Services","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133531893","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}

Also, the device will not have the powerful computation and storage ability. Many studies have focused on the lightweight authentication between the cloud server and the client in this environment. They can use the cloud server to help sensors or proxies to finish the authentication. But in the client side, how to create the group session key without the cloud capability is the most important issue in IoT environments. The most popular application network of IoT environments is the wireless body area network (WBAN). In WBAN, the proxy usually needs to control and monitor user's health data transmitted from the sensors. In this situation, the group authentication and group session key generation is needed. In this paper, in order to provide an efficient and robust group authentication and group session key generation in the client side of IoT environments, we propose a lightweight authentication scheme with dynamic group members in IoT environments. Our proposed scheme can satisfy the properties including the flexible generation of shared group keys, the dynamic participation, the active revocation, the low communication and computation cost, and no time synchronization problem. Also our scheme can achieve the security requirements including the mutual authentication, the group session key agreement, and prevent all various well-known attacks.","PeriodicalId":406787,"journal":{"name":"Adjunct Proceedings of the 13th International Conference on Mobile and Ubiquitous Systems: Computing Networking and Services","volume":"42 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126752079","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 this paper, we propose a method that estimates the walking speed and walked section of a pedestrian by using a smartphone equipped with a magnetometer. To grasp people flow velocity, the walking speed of a pedestrian is an important scale. Besides this, to grasp low flow velocity spots such as an intersection and an area in front of a door, we need to estimate the walked section, that is, the area between two points that a pedestrian walked within a period of time. In our proposed method, first we measure magnetic field data series while a participant is walking, and we generate magnetic signatures by relating each magnetic field datum to the corresponding position. Secondly, we detect partial magnetic signature that is similar to the magnetic field data series of an unknown walked section by using DTW (Dynamic Time Warping), and we obtain the walked section from the detected partial magnetic signature. Finally, we calculate walking speed from the distance of walked section and walked time. We conducted an experiment to evaluate the accuracy of walking speed estimation and walked section estimation. The results in a crowded passage showed that the average error of walking speed estimation was 0.09 m/s and the average error of walked section estimation was 0.7 m in the proposed method.","PeriodicalId":406787,"journal":{"name":"Adjunct Proceedings of the 13th International Conference on Mobile and Ubiquitous Systems: Computing Networking and Services","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127202444","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}
