Abstract
An apparatus and method for discovering and monitoring a collection of nodes in a downhole network may include receiving data packets originating from several downhole nodes. These packets may be read to extract a unique identifier and hop count for each of the nodes. This information may then be used to create entries in a network topology table corresponding to each of the downhole nodes. Each entry may contain unique identifier identifying the respective node and a hop count identifying a location of the node within the downhole network. The apparatus and method may further include modifying one or more entries in the topology table having conflicting hop counts to ensure that the hop counts of each entry are unique.
