Jianguo Huang, Sihan Fu · International Journal of Autonomous and Adaptive Communications Systems · 2022
In the traditional sensor network low beacon node localisation method, it is easy to be attacked by false routing, which seriously affects the localisation accuracy. A location algorithm based on multi - space key distribution algorithm is proposed. By using the key information of multiple key Spaces brought by sensor nodes, the paired keys in the information are accurately calculated. Routing messages are encrypted and authenticated to effectively prevent spurious routing attacks. The hopping number information and distance information between beacon nodes are used as training datasets. The least square method is learned to realise the localisation of sensor network low beacon nodes. Simulation results show that the algorithm can locate low beacon nodes quickly and accurately.
