路由协议设计是集群无人机网络的主要挑战之一。由于网络拓扑动态、复杂度低、无人机设备数量大的特点，现有基于网络拓扑信息的路由协议和路由表更新不适用于集群无人机网络。在本文中，提出了一种支持随机网络编码（RNC）的路由协议来支持高效的路由过程，该过程不需要网络拓扑信息或预先确定的路由表。使用所提出的路由协议，可以显着加快路由过程，因为每个转发无人机可能已经在前一跳中偷听到了一些编码数据包。结果，可能需要一些跳来传送一些编码分组，并且在整个路由过程中可能需要完成更少的跳。进行了相应的仿真研究，证明我们提出的路由协议能够促进更有效的路由过程。
Routing protocol design is one of the major challenges for swarm UAV networks. Due to the characteristics of a dynamic network topology, the low-complexity and the large volume of UAV devices, existing routing protocols based on network topology information, and routing table updates are not applicable in swarm UAV networks. In this paper, a Random Network Coding (RNC) enabled routing protocol is proposed to support an efficient routing process, which does not require network topology information or pre-determined routing tables. With the proposed routing protocol, the routing process could be significantly expedited, since each forwarding UAV may have already overheard some encoded packets in previous hops. As a result, some hops may be required to deliver a few encoded packets, and less hops may need to be completed in the whole routing process. The corresponding simulation study is conducted, demonstrating that our proposed routing protocol is able to facilitate a more efficient routing process.
