The process of topology discovery in IoT networks is currently one of the most important issues due to the increasing size of networks.
Traditional centralized approaches provide a good solution to this problem but, as the size of the network increases, they run into scalability problems in addition to the typical problems of centralized solutions, such as the concept of single point of failure and higher computational power required by the central node.
For this reason, in a network where all sensors have the same characteristics in terms of resources and computational capacity, the process of topology discovery should be addressed using a distributed approach through which each node can start and complete autonomously the entire process.
In this work, different criteria were designed to select nodes which are then used to obtain information about the topology. The aim is to understand which method can be the one that allows completing the discovery process in the minimum time, using the minimum number of bytes.
