Applications of Internet of Things

This book introduces the Special Issue entitled Applications of Internet of Things of ISPRS International Journal of Geo-Information. Topics covered in this issue include three main parts: (I) intelligent transportation systems (ITSs) (II) location-based services (LBSs) and (III) sensing techniques and applications. Three papers on ITSs are as follows: (1) Vehicle positioning and speed estimation based on cellular network signals for urban roads by Lai and Kuo; (2) A method for traffic congestion clustering judgment based on grey relational analysis by Zhang et al.; and (3) Smartphone-based pedestrians avoidance behavior recognition towards opportunistic road anomaly detection by Ishikawa and Fujinami. Three papers on LBSs are as follows: (1) A high-efficiency method of mobile positioning based on commercial vehicle operation data by Chen et al.; (2) Efficient location privacy-preserving k-anonymity method based on the credible chain by Wang et al.; and (3) Proximity-based asynchronous messaging platform for location-based Internet of things service by Gon Jo et al. Two papers on sensing techniques and applications are as follows: (1) Detection of electronic anklet wearers groupings throughout telematics monitoring by Machado et al.; and (2) Camera coverage estimation based on multistage grid subdivision by Wang et al.
