Techniques for Monitoring and Discovering the Children

Bluetooth Low Energy (BLE) standard speci?es a wide range of parameter values for neighbor discovery process (NDP). The parameter values used during neighbor discovery directly affect the persuance of the NDP. Therefore, an optimal parameter setting is essential to achieve the best trade-off between discovery latency and energy consumption. Analytical model can offer a bene?cial guideline for such parameter selection. In this paper, we propose a general model for analyzing the performance of NDP in the BLE networks. In this model, the operations of the scanner and the advertiser, which are two main components of NDP are expressed on the distinct-time axis. Based on the Chinese Remainder Theorem, the discovery suspension and energy consumption of advertiser are derived. When considering that BLE is one of candidate communication technologies for Internet of Things (IoT), the proposed model is expected to be very useful in setting the default or initial values of NDP parameters for various IoT applications.
