Systems and methods for determining locations of wireless sensor nodes in a network architecture having mesh-based features for localization
First Claim
1. A computer-implemented method for localization of sensor nodes in a wireless network, comprising:
- causing, with processing logic of a hub, the wireless network having sensor nodes to be configured as a first mesh-based network architecture for a first time period for localization;
determining, with the processing logic of the hub, localization of at least two sensor nodes using at least one of frequency channel overlapping communications, frequency channel stepping communications, and multi-channel wide band communications for at least one of time of flight and signal strength techniques; and
causing, with the processing logic of the hub, the wireless network to be configured in a second tree network architecture having narrow-band communications upon completion of 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 for localization. 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 further includes causing the wireless network to be configured in a second network architecture having narrow-band communications upon completion of localization.
