Abstract
The application discloses a kind of unmanned aerial vehicle network routing methods based on radio environment map, comprising the following steps: using each node to update network topology according to the spectrum interference prediction information of radio environment map;Network is modeled as a weighted graph, wherein the weight of the edge between two adjacent nodes is a function related to the position of interferer, each node updates the corresponding routing path in real time according to local neighbor table, two-hop neighbor table and topology table.The application combines table-driven routing protocol and radio environment map, joint network layer and physical layer / link layer discovery routing to bypass spectrum interference area, realize stable routing between unmanned aerial vehicles in spectrum interference environment, with higher packet delivery rate, throughput.
