Research on node maintenance routing coverage algorithms in sensor networks can improve node coverage and node activity in sensor networks. This paper proposes a node preserving routing coverage algorithm for sensor networks based on compressed HMAC. Firstly, based on the VGG-F network structure, high-dimensional features of the sensor network layer are extracted to maximise the amount of information carried by the hash code. Secondly, a feature extractor is designed using compressed HMAC algorithm. Then, uniform coverage of the target area is achieved according to the force balance conditions of the acting nodes. Finally, the compressed HMAC method is used to achieve target node division, and the coverage algorithm is used to optimise node retention routing and mobile coverage. The experimental results show that the coverage rate of this method can reach up to 99%, and the node utilisation rate is high.
