Abstract
A network information apparatus (400), system (100) (200) and method for distributing network information in a multi-channel (MC) wireless network (100) (200), comprising a network information module (400) that implements inter-channel communication of network information in an MC network according to a pre-determined network information sharing procedure and keeping an own cache (401) of each node refreshed and free of out-of-date information, and, for an active proxy-based sharing procedure thereof only, adapting to changes in node/channel associations, suppressing duplicate inter-channel information, and synchronizing own clocks (404) of each node.
