Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0020] In the following description, this specification abbreviates the directional time-division link scheduling method suitable for wireless mesh networks proposed by the present invention as LSCT (Links Scheduling for Concurrent Transmissions). The specific implementation steps of LSCT are given below:
[0021] Step 1: According to the beamwidth of the directional antenna used in the physical layer and the geographical location information of the node itself, calculate the conflict set of all transmission links in the network, and obtain the conflict link matrix of the entire network.
[0022] 1. Link conflict set
[0023] If two links collide and interfere with each other when transmitting in parallel at the same time, they are called conflicting links. as attached figure 1 As shown in (a), node R aligns the antenna direction to node S...
