ABSTRACT
A precision positioning system with energy efficiency is of great necessity for guaranteeing personnel safety in underground mines. The location information of the miners' should be transmitted to the control center timely and reliably; therefore, a heterogeneous network with the backbone based on high speed Industrial Ethernet is deployed. Since the mobile wireless nodes are working in an irregular tunnel, a specific wireless propagation model cannot fit all situations. In this paper, an underground localization system is designed to enable the adaptation to kinds of harsh tunnel environments, but also to reduce the energy consumption and thus prolong the lifetime of the network. Three key techniques are developed and implemented to improve the system performance, including a step counting algorithm with accelerometers, a power control algorithm and an adaptive packets scheduling scheme. The simulation study and experimental results show the effectiveness of the proposed algorithms and the implementation.

f7-sensors-15-12358: The value of the RSSI record by two nodes.

Mentions: As shown in Figure 7, the packet transmitted from Node A to Node B is defined as the forward channel and Node B to Node A as the reverse channel. Due to the differences among devices, the antenna and PCB, the values of the RSSI in the forward channel and reverse channel are almost at the same level within a certain error range. This conclusion is also suitable for the value of the received power, since the estimate of the received power is from the RSSI in the nanoLOC chip.
