1. A method of determining transmit power at a first node in a wireless network, comprising:
- receiving one or more messages from a second node, the one or more messages indicating a three-dimensional position of the second node and a directional antenna associated with the second node that transmitted at least one of the one or more messages;
determining a vector between the second node and the first node based on the three-dimensional position of the second node;
determining a gain of the directional antenna corresponding to the determined vector to produce a transmit antenna gain (XmitAntGain); and
determining the transmit power for transmitting to the second node based on the transmit antenna gain.

Abstract
A system (105) determines a power level for transmitting to a neighboring node in a wireless network. The system (105) receives a message indicating a three-dimensional position and orientation of the neighboring node and a type of directional antenna of the neighboring node that transmitted the message. The system (105) determines the power level for transmitting to the neighboring node based on the three-dimensional position and orientation of the neighboring node and the type of the directional antenna.
