Abstract

An optimizing method for a relational structure is presented. Firstly, a zone controller (ZC) receives a relational structure information related to a located zone and executes a classification for multiple sub-relational structure information thereof. The ZC then executes searching and calculation respectively based on different types of the sub-relational structure information, and receives multiple optimum solutions for each type of the sub-relational structure information respectively. Finally, the ZC establishes different types of sub-relational structures based on the multiple optimum solutions, wherein each sub-relational structure comprises at least one wireless node of the located zone, and connects with the multiple sub-relational structures for establishing the relational structure.
