Development of Sensor Registry System-Based Predictive Information Service Using a Grid

Abstract

A sensor registry system (SRS) registers sensor metadata and provides them for a seamless semantic process. Recently, network coverage information-based SRS (NC-SRS) was developed to provide sensor information filtering by combining path prediction and network coverage checks. However, the NC-SRS has problems caused by issues such as termination of OpenSignal service and pre-building road segments. Therefore, this paper proposes a sensor registry system-based predictive information service (SRS-PIS) using a grid. SRS-PIS predicts a path based on the grid, checks the network coverage, and filters the sensor. This paper presents a grid-based real-time path prediction algorithm and an algorithm for grouping network service-disabled areas. To obtain network coverage information, we constructed and implemented a grid-based coverage map through experiment to measure the signal strength. As an evaluation, we compared features among SRS-based systems and SRS-PIS, and compared advantages and disadvantages between segment-based and grid-based methods.

LSTM-Based Path Prediction for Effective Sensor Filtering in Sensor Registry System

“…The other is the sensor network for the mobile device to connect directly and obtain data from sensors. In the applied scenario [ 10 ], the research area is divided into grid cells c. is a list of sensors s linked to the cell c . The trajectory of human movement is a sequence composed of a series of cells , where the superscript indicates the time, is the current cell of the user, and is the starting cell of the trajectory.…”

“…Existing optimization methods for sensor filtering in SRS [ 8 , 9 , 10 ] focus on the first connection, i.e., how to improve the reliability of acquiring metadata. There is a denial-of-service area in which the mobile device cannot communicate with SRS in these efforts.…”

“…1. The denial-of-service area is grouped by measuring the reference signal received power (RSRP) of cellular networks within the research area [ 9 , 10 ]. In recent years, with the popularity of commercial 4G services and the improvement of cellular network infrastructure, the quality of service between SRS and mobile devices can be guaranteed.…”
