Systems and methods for determining locations of wireless sensor nodes in a network architecture having mesh-based features for localization

Abstract

Systems and methods for determining locations of wireless sensor nodes in a network architecture having mesh-based features are disclosed herein. In one example, a computer-implemented method for localization of nodes in a wireless network includes causing, with processing logic of a hub, the wireless network having nodes to be configured as a first network architecture for a first time period forlocalization. The method further includes determining, with the processing logic of the hub, localization of at least two nodes using at least one of frequency channel overlapping communications, frequency channel stepping communications, multi-channel wide band communications, and ultra-wide band communications for at least one of time of flight and signal strength techniques. The method furtherincludes causing the wireless network to be configured in a second network architecture having narrow-band communications upon completion of localization.

AI Technical Summary

Problems solved by technology

First, in low-power environments where nodes transmit and receive infrequently, the positioning process can be slow or impossible; on the other hand, fast, accurate and robust positioning can consume too much power due to the need to transmit repeated bursts power of

Second, in tree-like networks, triangulation may not be feasible due to the inability to establish a sufficient number of path lengths between pairs of nodes

Third, in indoor environments, limited localization accuracy may prevent determining the exact room a particular node is located in; for example, existing accuracy may prevent determining which side of a wall a particular node is located on
