Wireless meshed network broadcast communication method facing to industry monitoring application

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] The present invention has utilized the characteristic of the network information transmission mode of industrial monitoring application, according to the wireless Mesh network (network structure diagram such as figure 1 As shown), the inherent dynamic spanning tree with the gateway device as the root improves the traditional broadcast strategy: first, all leaf nodes do not forward any broadcast messages; second, non-leaf nodes only need to forward messages from The broadcast message of its parent node or child node. details as follows:

[0016] When a node receives a broadcast message, it needs to decide two things (the process is as follows: figure 2 shown):

[0017] 1. Whether to receive the message

[0018] a) If the non-repeated broadcast message is received;

[0019] b) Otherwise, do not receive the message;

[0020] 2. Whet...
