[0023] Reference figure 1 In the present invention, combined with actual equipment, each equipment is equipped with a multi-faceted directional antenna, and the omnidirectional coverage of the network is guaranteed by means of switching. The realization of the neighbor node discovery of the directional centerless self-organizing network is as follows:
[0024] (1) The node determines the number of antenna beam directions N according to the number of directional antenna switching, and numbers each beam direction, taking N beam directions as a scanning period; N is a natural number greater than 1;
[0025] (2) The node starts beam scanning, and randomly determines its own transceiver status in each beam direction under the current beam scanning period, and the transceiver status includes sending status, receiving status, and silent status;
[0026] (3) The node determines the current scanning beam direction and the node's receiving and sending status. If it is in the sending state, the...
