Abstract:
1. A system for distributing network information in a multi-channel wireless network communication system, comprising: a set of a plurality of N channels {i} including a non-empty subset of foreign channels C(i) for each home channel i of the set of channels {i} and for each home channel i of the set of channels {i}, a set of at least one node S(i) tuned to the channel i; and a network information module resident at each node and comprising a channel visiting mechanism whereby, for each channel i of the set of the plurality of N channels {i}, current network information is distributed to the set of at least one node S(i) tuned to channel i and maintained thereby in a local own cache storage using a cache maintenance component, said channel visiting mechanism comprising a source-based mechanism and a proxy-based mechanism, wherein a proxy node p(i) is defined as at least one node of the sets S(i), i=1, . . . , N that periodically visits each foreign channel j of C(i) to participate in a pre-determined network information sharing procedure therewith and thereafter with the home channel of the proxy node and a source node is a network node S(i) of channel i that sends network information to each node of each channel of the set of N channels.
