Under a high-antagonistic battlefield, aiming at the paradox under between the intermittent link of bottom communication and the continuous demand of upper communication, in this paper, we propose a multi-UAV synergetic communicating route plan to solve the UAVs communication problems of multiple communication targets and message priority by combining the correlation theories and methods of DTNs, the raster map and the Ant Colony Algorithm. Ultimately, we confirm the validity of the method by simulations.
