Communication link accessibility aware navigation
First Claim
1. A method of communication link accessibility aware navigation, the method comprising:
- querying a communication link accessibility map based on a location of interest provided by a path planner for a communication node;
receiving a communication link accessibility indicator representing a communication link characteristic associated with the location of interest in response to querying the communication link accessibility map;
determining a communication link accessibility weight based on a mission model that defines priorities and constraints for making path planning decision including maintaining a communication link of the communication node;
applying the communication link accessibility weight to the communication link accessibility indicator;
moving the communication node;
monitoring for a communication link loss at the communication node; and
providing a list to the path planner of one or more known positions where at least one communication link was previously established to assist in modifying the path plan to restore communication; and
determining, using the path planner, a cost associated with returning to one or more of the known positions to restore communication.

Abstract
A method of communication link accessibility aware navigation is provided that includes querying a communication link accessibility map based on a location of interest provided by a path planner for a communication node. A communication link accessibility indicator is received representing a communication link characteristic associated with the location of interest in response to querying the communication link accessibility map. A communication link accessibility weight is determined based on a mission priority of maintaining a communication link of the communication node. The communication link accessibility weight is applied to the communication link accessibility indicator.

10. A communication node for communication link accessibility aware navigation, the communication node comprising:
-
a processor; and memory having instructions stored thereon that, when executed by the processor, cause the communication node to; query a communication link accessibility map based on a location of interest provided by a path planner for the communication node; receive a communication link accessibility indicator representing a communication link characteristic associated with the location of interest in response to the query of the communication link accessibility map; determine a communication link accessibility weight based on a mission model that defines priorities and constraints for making path planning decision including maintaining a communication link of the communication node; apply the communication link accessibility weight to the communication link accessibility indicator; move the communication node; monitor for a communication link loss at the communication node; and provide a list to the path planner of one or more known positions where at least one communication link was previously established to assist in modifying the path plan to restore communication; and determine, using the path planner, a cost associated with returning to one or more of the known positions to restore communication. - View Dependent Claims (11, 12, 13)
