Abstract: In a packet communication network, a method and apparatus for packet switched transport is provided among intelligent nodes wherein the duty cycling of the intelligent nodes is minimized in order to maximize power life using a synchronization algorithm that assures all nodes are able to propagate information through the network without undue use of transmission and reception power. Frequency hopping time-division multiple access supports packet communication between intelligent nodes via assigned directed links, each link being assigned to a time-channel offset (cell) in a superframe, so that a link carrying a packet string between any two intelligent nodes is active only during its assigned time slot. The result is efficient use of spectrum and minimal expenditure of power.

Abstract: In a packet communication network, a method of packet switched transport is provided using digraphs defining paths among nodes in which a graph identifier, instead of a literal destination address, is used to determine paths through the network. The nodes themselves implement a real-time mesh of connectivity. Packets flow along paths that are available to them, flowing around obstructions such as dead nodes and lost links without need for additional computation, route request messages, or dynamic routing tree construction.
