Expected Response Time Model Considering Churn Rate for Dynamic IoT Devices


Background/Objectives: IoT has dynamic characteristics that the devices are freely joined or leave the networks. In this paper, we propose an expected response time model in a dynamic IoT environment. Methods/Statistical Analysis: We analyze the expected response time of an IoT query for star, tree, and mesh topologies. We evaluate the proposed model by comparing how it affects to response time according to the network topology and the bounce rate. Findings: We found that the impact of churn rates shows significantly different results under various topologies. Thus, churn rate is an important consideration in dynamic device replacement procedure that replaces a faulty device with a relatively healthy device. Improvements: Our analytical tool can be used for a decision mechanism of the IoT node that will operate most effective for time-critical IoT applications.
