Expected Transmission Count (ETX) is a metric used in wireless networking to evaluate and optimize the performance of communication links in ad hoc networks and wireless mesh networks. It is a measure of the number of transmissions (both successful and unsuccessful) that are expected to occur for a packet to be successfully delivered from a source node to a destination node over a given link.
