Efficient Construction of Detector Set for Query Loss Recovery in Sensor-IoT Networks
Rui Teng and Julian Webber
Sensor-IoT (Internet of Things) networks allow users, cloud, or edge servers to query and collect data from sensor-IoT devices. It is important to enable the resilience of failures in data query and collection. This paper studies the issue of functional structure to enable the mutual support among sensor-IoT devices in discovery and recovery of query losses with low cost. We especially address the problem of how to configure the sensor-IoT network with a sufficient but small number of detector-role nodes that perform the monitoring role for nearby nodes. We propose two schemes. One is random selection of detectors at each sensor-IoT node. Another scheme allows each IoT-sensor node to choose the its detectors in an order of node IDs. The evaluation results show the effectiveness in the construction of detector sets with a small number of sensors by using the proposed schemes. Moreover, we verify that the ID-sequence based scheme is more effective in detector selection to reach the target of easy construction of detector set using a small number of detectors.
