Embodiment Construction
[0029] The peer-to-peer network super node selection and resource search method for introducing node importance involved in the present invention can be divided into three steps: 1) calculating the node importance, 2) determining the super node according to the importance, and 3) resource search process. These three aspects are described below.
[0030] 1. Calculate the importance of nodes
[0031] 1.1 Calculation method of node importance
[0032] The importance of a node is a measure of the service it can provide to the network, and it is related to the number of neighbors and the topological relationship of the node. The most direct way to measure the importance of nodes is to count the number of packets forwarded by each node in the recent period. If the time period for statistics is too short, sudden traffic will affect the estimated results; if the time period for statistics is too long, it cannot reflect the changes of network traffic in the current network in time. ...
