Secure routing method for converged network of wireless sensor network and computer network

The invention discloses a secure routing method for a converged network of a wireless sensor network and a computer network, which comprises the following steps: the entire converged network is divided into a plurality of clusters, wherein each cluster comprises a cluster head node selected before each turn of communication and a plurality of member nodes; after the clusters are established, a sink node initiates and establishes a multihop multipath for nodes among clusters by broadcasting a Route-Find-Pkt; and the cluster head node monitors the forwarding behavior of a neighbor cluster head node and adjusts the belief value of the neighbor cluster head node according to a monitoring result, and the sink node collects the belief value information notified by each cluster head node in the network, estimates the running status of each cluster head node in real time, generates different grades of notification messages according to an estimation result, and notifies each cluster head node. Under the premise of fu
