Abstract:
In recent years, the research and application of Unmanned Aerial Vehicle (UAV) network has become a significant topic. The mobile ad hoc network established by UAV nodes can be more efficient to complete various tasks in a harsh environment. Plenty of research focuses on the routing protocol, which is an important factor to play group advantage of UAVs. In the swarm network with UAV nodes, nodes failure or mobility may cause routing failure, which results in communication failure or longer delay. The existing routing-repair mechanisms are accompanied by a great deal of control overhead, which cannot solve the problem mentioned above effectively. This article analyses the advantages and disadvantages of Temporally Ordered Routing Algorithm (TORA), and proposes a routing protocol named Rapid-reestablish Temporally Ordered Routing Algorithm (RTORA). RTORA adopts reduced-overhead mechanism to overcome adverse effects caused by link reversal failure in TORA. The simulation results using OPNET demonstrate that RTORA has less control overhead and smaller delay than TORA.
