A system maintains communication between a plurality of unmanned vehicles within an environment. The system includes a sensor component and an evaluator. The sensor component senses objects within the environment. The sensor component is located on a first unmanned vehicle. The evaluator evaluates data from the sensor component. The evaluator is located on the first unmanned vehicle. The evaluator compares data for the first unmanned vehicle and a second unmanned vehicle and determines whether a trajectory of one of the first and second unmanned vehicles may be modified to maintain communication between the first unmanned vehicle and the second unmanned vehicle.
