On Building Communication Maps in Subterranean Environments

Popis výsledku v původním jazyce

Communication is of crucial importance for coordinating a team of mobile robotic units. In environments such as underground tunnels, the propagation of wireless signals is affected by nontrivial physical phenomena. Hence, both modeling of the communication properties and the consequent task to estimate where communication is available becomes demanding. A communication map is a tool assessing the characteristic of communication between two arbitrary spatial coordinates. The existing approaches based on interpolation of a priori obtained spatial measurements do not provide precise extrapolation estimates for unvisited locations. Therefore, we propose to address the extrapolation of the signal strength by a position-independent model based on approximating the obstacle occupancy ratio between the signal source and receiver. The proposed approach is compared to the existing attenuation models based on free-space path loss and spatial projection using a natural cave dataset. Based on the reported results, the proposed approach provides more accurate predictions than the existing approaches.
