Research On UAV Ad Hoc Network Technology

The experience of Recent several local wars shows that: modern warfare is based on information-centric warfare. Since the network plays an important role in information wars, modern warfare is also known as "network-centric warfare". As UAV Ad hoc network is an important component of network-centric warfare, and UAV has the advantages of low cost and high security and so on, each of military powers pay more and more attention to research work of the UAV and network battles.After summarizing and analyzing the recent UAV Ad hoc network methods at home and abroad, the paper makes a deep research in relay communications network and routing algorithm. To the problem in communications network and routing algorithm. The research work is mainly as the following parts:To the problems of the change of Network connectivity caused by the factors of node mobility and network expansion, a UAV relay communication system for terrestrial wireless networks is designed. The solution is given to the implementation of relay of the ground wireless network remote communication for UAV. In this paper, single UAV communication system, multi-UAV communication systems and UAV hierarchical communication system are respectively designed.For the link instability and network congestion problems of UAV Ad hoc networks multimedia data transmission, a routing algorithm for UAV Ad hoc networks multimedia data transmission is introduced. The algorithm is full account of geographic information, speed, direction of motion, congestion, these four factors have the impact of selecting the next hop node, which can achieve the goals of improving the link performance.In order to test the validity of the algorithm,the GPSR algorithm and the improved algorithm proposed by this paper are compared with the simulation experiments. the experimental results demonstrate that the proposed algorithm can guarantee the UAV multimedia data transmission effectively.
