In order to solve the problem of maintenance messages increased linearly with the number of neighbors in the ring-like P2P network and traditional token mechanism could not control the token number, we propose method of control speed token to maintain the ring-like P2P network. Token transmit in ring-link P2P network in the form of message, and node information could record in token in order to keep the structure of network for other nodes. P2P network use control speed parameter to reduce the number of tokens. Simulation shows that control speed parameter could effectively reduce the number of token in P2P network; with the increasing scale of the network, the average maintenance costs of node remain unchanged.

Generally, the parallel-link Coordinate Measuring Machine(CMM) has higher measuring accuracy and more flexible probe posture than the serial-link CMM. Therefore, theoretical and experimental research for the parallel-link CMM has become a hot topic for both industry and academia. In this paper, the virtual prototype of the 6-DOF parallel-link CMM was designed using the graphics functions in the OpenGL library. On the basis of above, a bounding box algorithm was developed to detect collision in the movement process, the detail method of the detection and the programming are also presented. This method improves not only the detection efficiency but also the reality of virtual prototype system.

Vegetable grafting is one of the most effective means to resist soil-born diseases and to improve yield. Manual grafting has the problems of low production and poor grafting quality, so grafting robot is significant for the development of vegetable grafting production. Based on the grafting principles, the development and current status of domestic and foreign automatic grafting machine was analyzed. Some problems restricting the advancement of grafting machine are found out.
