Abstract

The invention provides a message filtering method and device in a Bluetooth wireless grid network, and the method comprises the steps: receiving a first message through Bluetooth wireless grid connection by Bluetooth intelligent equipment, inputting the first message into N hash functions of different types for operation, obtaining N hash values corresponding to the N hash functions, and then comparing the N hash values with values of N elements of a stored hash array to judge whether the first message is a repeated message, if the first message is judged to be a repeated message, filtering the first message, and otherwise, processing the first message. According to the method, the memory and processing resource consumption of the equipment can be reduced in a resource limited scene, and the message processing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular, to a message filtering method and device in a Bluetooth wireless mesh network. Background technique [0002] With the wide application of IoT technology, Bluetooth technology has become a major wireless communication technology, which is widely used in smart home, automotive IoT, industrial manufacturing, smart medical and other fields. However, the scenario of the Bluetooth wireless mesh network is complex, and the message forwarding between devices appears as a flooded message, and the repeated forwarding of the same message hinders the normal use of Bluetooth Mesh. [0003] The message filtering scheme in the prior art is to save a certain number of historical messages by setting a message array, and then compare the received new messages with the historical messages saved in the message array one by one, and discard the same messages if they are the...
