Optimal Communication Node Selection Algorithmfor Intrusion of Internet of Things

Aiming at the problem that the traditional communication node selection algorithm could not accurately perform the optimal nodeselection, and could not effectively guarantee the effective communication of the Internet of Things, we proposed an optimal communication node selection algorithm for intrusion of Internet of Things based on node information redundancy. Firstly, the transfer characteristics model of communication nodewas constructed, and the frequency hopping node and noise node undernetwork intrusion were calculated. Secondly, the communication distribution sequence analysis model was designed to calculate the node information redundancy and the extremum of the communication node. According to the node information redundancy calculation results, the interference nodes were eliminated and the optimal communication node was selected according to the extremum. Finally, the simulation experiment of the optimal communication node selection algorithm was carried out. The experimental results show that the proposed algorithm can quickly and accurately select the optimal node under the intrusion of Internet of Things, has strong anti jamming ability, and the comprehensive performance of the algorithm is better than other optimal communication node selection algorithms.
