The localization of sub-network, the agency nodes selection and traffic flow detection are defined as follow. Because each wind turbine is located at a given area, and the localization of sub-networks is stationary. In each sub-network, the nodes position can be formed by a convex polytope based on computing convex hulls in 3-Space principles, and obtain the border of sub-network and the vertices of convex polytope [19]. After some predetermined convergence time, one vertices of convex polytope border would be selected as an agency node which lost connection to the most number of neighbors. If more than one border nodes obtain the same value, which has more neighbors and/or the highest node ID, and selected as an agency node. These agency nodes will represent each sub- network, which can be denoted as ANi where the set of ith sub- networks is. And then the RNs are placed in the vicinity of these agency nodes, which are forming a new network topology. Additionally, the RNs are given more capability than SNs, such as more energy storage, higher computation ability, and longer communication radius.
