AUTONOMOUS TRANSPORT NAVIGATION TO A SHIPPING LOCATION USING ELEMENTS OF A WIRELES NODE NETWORK
First Claim
1. A method for navigating to a shipping location by an autonomous transport vehicle using a plurality of nodes in a wireless node network, comprising:
- detecting, by a mobile master node associated with the autonomous transport vehicle, a signal broadcast from an ID node associated with the shipping location, wherein the mobile master node is one of the plurality of nodes and is operative to communicate directly with a server in the wireless node network over a first communication path, and wherein the ID node is another of the plurality of nodes and is operative to communicate directly with the mobile master node over a second communication path but not operative to communicate directly with the server over the first communication path;
instructing, by the mobile master node, the ID node to lower a power level of the signal broadcast from the ID node;
identifying, by the mobile master node, the signal broadcast from the ID node with the lowered power level;
determining, by the mobile master node, a direction of the ID node relative to the mobile master node based upon the detected signal with the lowered power level; and
navigating, by the mobile master node, to the ID node associated with the shipping location based upon the determined direction.

Abstract
Methods, media, and node-enabled autonomous transport vehicles are described for navigating to a shipping location using a plurality of nodes in a wireless node network. A node associated with the autonomous transport vehicle, such as a mobile master node, detects a signal broadcast from an ID node associated with the shipping location, and instructs the ID node to lower a power level of the broadcast signal. The mobile master node identifies the signal broadcast from the ID node with the lowered power level, and determines a direction of the ID node relative to the mobile master node based upon the detected signal with the lowered power level. The mobile master node then navigates to the ID node associated with the shipping location based upon the determined direction, which may involve providing the determined direction to an input for the vehicle'"'"'s control system.
