Abstract:

Unmanned aerial vehicles have been widely used in military and civil fields, and unmanned aerial vehicle networking has become a hot research topic. Neighbor discovery is a prerequisite step to complete a network. In this study, the 3-handshake non-cooperation neighbor discovery (3-NCND) protocol is first improved. Then a support vector machine (SVM) algorithm is integrated and a 3-handshake and SVM cooperative neighbor discovery (3-SVMCND) protocol is proposed. SVMs are trained as classifiers and then added to the neighbor discovery protocol. The protocol can intelligently recommend its own neighbor nodes to the target nodes and can reduce the number of neighbor node recommendations while improving the speed of neighbor discovery. In this study, three performance indices of neighbor discovery, namely, slot number, neighbor discovery rate, and energy consumption, are compared in a simulation experiment. Results show that 3-SVMCND has a faster discovery speed and higher neighbor discovery rate than those of 3-NCND.

Key words: unmanned aerial vehicle, support vector machine (SVM), binary coding, collaborative neighbor discovery (CND), intelligently
