Abstract:
1. In a multi-hop packet-switched communication network, a method for routing packets comprising: providing at least a first intelligent node and a second intelligent node, said first intelligent node and said second intelligent node serving as intelligent nodes in said packet communication network and each said first intelligent node and said second intelligent node having independent intelligence for storing and redirecting units of communication traffic; providing at least one digraph, each said digraph being expressed as routing information for directional links at each intelligent node in the network, including at least a first intelligent node having a plurality of outgoing directional links from said first intelligent node to a second intelligent node, wherein each directed link in said digraph is specific to a time slot in a time-frequency space; generating a plurality of packets, each of said packets having a header; wherein, at each said individual intelligent node that is operative to receive a packet, determining: a) whether the packet is intended for said individual intelligent node; and b) whether the packet is of interest to said individual intelligent node; directing, via said routing information at each said intelligent node, said packets to flow between selected ones of said intelligent nodes according to one of said digraphs in accordance with a synchronized time and frequency communication plan; otherwise turning off transmission and receiving elements of said intelligent nodes to minimize power consumption when not receiving and directing said packets.
