Multi-antenna autonomous switching method for star-shaped self-organizing network

Abstract

The present invention is a multi-antenna autonomous switching method for a star-shaped self-organizing network, and is characterized in that: the method comprises: Step 1. periodically broadcasting incoming network messages on network master node; Step 2: a slave node entering the network; Step 3. selecting a slave node antenna that has high communication energy with a master node antenna and strong signal to noise ratio; Step 4 Selecting a master node antenna that has high communication energy with the slave node antenna and strong signal-to-noise ratio; Step 5, through repeating step 2 to 4,determining antenna respectively for both master node and each slave node; step 6, determining a service time slot communication antenna when the master and slave node are at precise synchronizationtime slot and maintaining the network for next cycle. The method can solve performance degradation caused by dynamic changes of the star-shaped self-organizing network. The method has characteristicsof good topology adaptability and strong network reorganization ability, ensures continuous availability of a link and improves the network utilization rate of the star-shaped self-organizing network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and in particular to a multi-antenna autonomous switching method of a star self-organizing network. Background technique [0002] In the self-organizing network technology in the wireless environment, the star network is a self-organizing network with a relatively simple network structure and easy implementation. It is widely used in the field of multi-aircraft networking. After the star self-organizing network is completed, due to the needs of actual tasks, the network nodes are constantly moving and the network topology changes rapidly, which often leads to low network utilization and performance degradation. If the continuous availability of links and the robustness of the network topology cannot be guaranteed in the state of node mobility, the performance of the entire star network will be greatly affected. At present, there are not many researches to solve the problems of th...
