[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0041] The invention aims to solve the problems of data redundancy and fast energy consumption caused by excessive relaying of messages in the network due to the flooding algorithm, so that it is suitable for the wireless sensor network based on BLE mesh. The improved method combines the characteristics of BLE technology, uses three advertising channels to broadcast and receive messages, defines a new advertising packet format, and adds fields such as Hop. Forwarding in the direction of the node to limit the blind flooding of messages.
