    selecting the first neighbor node as an aggregation node for information about the local node,wherein the aggregation node outputs data that is a combination of data received from a plurality of different nodes and a number of neighbor nodes with which the local node is in direct communication is called a local number, wherein determining the first neighbor node further comprises determining that the first number of nodes is greater than the local number, and that no other neighbor node of the local node is in direct communication with more nodes than the first number of nodes.
