1. A method for determining a change in position of a location marker, comprising:
- determining, by the location marker, whether the location marker is in a motion state or a static state using sensors integrated into the location marker;
discovering, by the location marker in response to the determining, one or more reachable nodes;
calculating, by the location marker, distance measurements from the location marker to each of the one or more reachable nodes;
identifying, by the location marker, an environmental state of the location marker; and
providing, by the location marker, the environmental state and the distance measurements to a central position determination node based on the location marker being in the static state.

Abstract
The disclosure is directed to determining a change in position of a location marker. In an aspect, it is determined whether the location marker is in a motion state or a static state using sensors integrated into the location marker, in response to the determining, one or more reachable nodes are discovered, and distance measurements are calculated from the location marker to each of the one or more reachable nodes.

15. An apparatus for determining a change in position of a location marker, comprising:
at least one processor configured to; determine whether the location marker is in a motion state or a static state based on information from sensors integrated into the location marker; cause a transceiver of the location marker to discover, in response to the determination, one or more reachable nodes; calculate distance measurements from the location marker to each of the one or more reachable nodes; identify an environmental state of the location marker; and cause the transceiver to provide the environmental state and the distance measurements to a central position determination node based on the location marker being in the static state. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An apparatus for determining a change in position of a location marker, comprising:
a processing means for; determining whether the location marker is in a motion state or a static state based on information from sensors integrated into the location marker; causing a communication means of the location marker to discover, in response to the determination, one or more reachable nodes; calculating distance measurements from the location marker to each of the one or more reachable nodes; identifying an environmental state of the location marker; and causing the communication means to provide the environmental state and the distance measurements to a central position determination node based on the location marker being in the static state. - View Dependent Claims (30, 31)

32. A non-transitory computer-readable medium for determining a change in position of a location marker, comprising:
-
at least one instruction to cause the location marker to determine whether the location marker is in a motion state or a static state using sensors integrated into the location marker; at least one instruction to cause the location marker to discover, in response to the determining, one or more reachable nodes; and at least one instruction to cause the location marker to calculate distance measurements from the location marker to each of the one or more reachable nodes at least one instruction to cause the location marker to identify an environmental state of the location marker; and at least one instruction to cause the location marker to provide the environmental state and the distance measurements to a central position determination node based on the location marker being in the static state. - View Dependent Claims (33, 34)
