Dynamic distributed, multi-channel time division multiple access slot assignment method for a network of nodes
First Claim
1. A method for automatically managing the communication channel resources between two nodes having neighboring nodes in a network of transceiver nodes, wherein each node communicates during specific time slots and uses multiple frequencies on a time multiplex basis, the method comprising the steps of:
- storing a table of possible communication time slots and frequencies between nodes in the network at each node;
announcing and transmitting from a first node during a specific time slot, a selected transmit slot and frequency and the identification of a second node to all neighboring nodes of the first node comprising a first set of neighboring nodes;
transmitting from the first node a control packet containing;
the set of transmit slot and frequency pairs on which the first node is transmitting;
the set of slot and frequency pairs on which the first node is receiving; and
the set of slot and frequency pairs on which the first set of neighboring nodes are transmitting on; and
identifying in the tables of each of the nodes of the first set of neighboring nodes the announced selected transmit slot and frequency used to establish contention free communication on the selected transmit slot and frequency between the first and second nodes.

Abstract
A method for automatically managing the communication channel resources between two nodes having neighboring nodes in a network of transceiver nodes, wherein each node communicates during specific time slots and uses multiple frequencies on a time division multiple access basis includes the steps of storing a table of possible communication frequencies and time slots between nodes; and announcing and transmitting during a specific time slot, a selected transmit frequency and slot from a first node to a second node and all neighboring nodes of the first node. The announced frequency and slot have certain constraints on reuse within two hops of the transmitting node to thereby establish contention free communication on that frequency and slot between the first and second nodes.
