UAV relay network to provide communications in mobile ad hoc networks

Network connectivity can be affected by mobile networks mobility and extensions of the active area.This paper presents a method using an unmanned aerial vehicle(UAV) relay networks to support communication in mobile ad hoc networks.System models are given for ground node to UAV connectivity,ground node to ground node via UAV connectivity,and UAV to UAV connectivity.This paper also presents a weighted centroid UAV flight model with a flight control method for the UAV relay network.Simulations analyze the impact of the ground node active region,speed,and communication methods on the three types of network connectivity.The simulations also analyze the performance of the weighted centroid UAV flight method and the centroid UAV flight method.The simulations show that the weighted centroid UAV flight method more effectively supports ground node intra-domain communication than the centroid UAV flight method while the weighted method is less effective in supporting ground node connections to the UAV.
