wherein, w1And w2Representing preset weight parameters, dlidx (q) representing distribution parameters of the internet of things node q in the non-divided set, dist (q, s) representing the average communication hop count of communication between the internet of things node q in the non-divided set and the internet of things node s in the forwarding node set, and nfcvsu representing the total number of elements contained in cvsu;

After the communication parameters are obtained, the internet of things node with the largest communication parameters is not directly used as the forwarding node in the invention, because the distribution of the finally obtained forwarding nodes is not uniform enough due to the mode of only considering the communication parameters. Therefore, the invention selects the forwarding nodes by setting the distribution parameters, and the distribution parameters also consider the average distance between the current Internet of things node and the existing forwarding nodes, so that the larger the average distance is, the larger the distribution parameters are, thereby being beneficial to ensuring that the finally obtained forwarding nodes are more uniformly distributed, and further avoiding the problems that the forwarding time delay of the state data is increased due to the uneven distribution of the forwarding nodes, the state data of the medical equipment is influenced to be obtained in time, and the life safety of the patient is influenced.
Preferably, the general node transmits the status data of the medical device to the forwarding node closest to itself.
