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.
Claims19
A method, comprising:
- receiving, by a first node in an ad-hoc wireless network, a first message from a second node in the ad-hoc wireless network, the message comprising three-dimensional position data associated with the second node;
- selecting, by the first node, an antenna, from a plurality of antennas that transmit from the first node through the ad-hoc wireless network, where selecting the antenna is based on the three-dimensional position data associated with the second node;
- and
- transmitting, on the ad-hoc wireless network, a second message from the first node to the second node via the selected antenna.
A non-transient computer-readable medium containing instructions for controlling at least one processor in a device, the instructions comprising:
- one or more instruction for receiving data associated with a three-dimensional position of a node in an ad hoc wireless network, where the three-dimensional position relates to a latitude, longitude and altitude of the node;
- one or more instruction for selecting a directional antenna, from a plurality of directional antennas that transmit through the ad-hoc wireless network, where selecting the directional antenna is based on the three-dimensional position data;
- and
- one or more instruction for transmitting a message to the node via the selected directional antenna.
A first node in an ad-hoc wireless network, the first node comprising:
- a transceiver coupled to a plurality of antennas that transmit through the ad-hoc wireless network;
- a memory to store instructions;
- and
- a processor to execute the instructions in the memory to:
- receive, at the transceiver, data associated with a three-dimensional position of a second node in the ad-hoc wireless network,
- select an antenna, from the plurality of antennas, based on the received data associated with the three-dimensional position of the second node, and
- transmit, from the transceiver, additional data to the second node via the selected antenna.
A system comprising:
- means for receiving a message from a first node of a plurality of nodes in a wireless network, the message comprising a three-dimensional position and orientation associated with the first node, the orientation comprising heading, pitch and roll values associated with the first node;
- means for determining, based on the three-dimensional position and the orientation associated with the first node, a vector from a second node of the plurality of nodes to the first node;
- and
- means for selecting an antenna, from a plurality of antennas for transmitting data that transmit through the wireless network, based on the determined vector.
