Abstract: To improve the efficiency and reliability of communication in a large and high-density wireless network 100, it is beneficial to assign a subset of the plurality of nodes 500 being router nodes 200, and the rest of the nodes being non-router nodes 300. Thus, the dense wireless network 100 splits into a sparse core mesh network and many small star networks around each router node 200. However, to commission the plurality of nodes into such a hybrid topology can be quite complex and time-consuming. This invention discloses a commissioning method that makes use of one or more neighboring relationship established among the plurality of nodes to derive a proper role for an individual node, and then to configure the individual node to operate according to the role assigned. The disclosed commissioning method may be carried out semi-automatically or automatically.
