Abstract

An apparatus and method for a wireless home mesh network with a network topology visualizer is described. In one embodiment, the method may include collecting node topology information by a node of a wireless home mesh network, where the node topology information includes a list of neighbor nodes for the node. Thereafter, a communication socket is opened, and a node topology packet, including a lust of neighbor nodes, is transmitted in order to produce a global network topology map. Other embodiments are described and claimed.
