(English Abstract)
Internet of Things (IoT) is a technology to provide emerging applications, such as remote data collection. Recently, the active deployment of wireless sensors and the explosive increase in the number of mobile devices has enabled opportunistic data collection (ODC), in which mobile devices collect data from distributed sensors. In ODC, the sensor data can be collected without the additional overhead of installing and operating a network infrastructure. However, the time duration for data transfer cannot be guaranteed due to the unpredictable mobility of mobile devices in ODC. Therefore, existing studies have used a conservative flow control mechanism focusing on reliable data transfer. However, the conservative flow control degrades the data collection performance when the time duration for data transfer is sufficiently long. In this paper, an efficient flow control scheme was proposed for enhancing the data collection performance of ODC. The proposed scheme is based on the communication time between a mobile device and a sensor. The efficiency-oriented flow control mechanism is applied with a long communication time, while a short communication time leads to the reliability-oriented flow control mechanism. By using the proposed scheme, the data collection performance can be enhanced without degrading the reliability of data transfer.
