A method and system for managing communication resources between nodes in a network, and more particularly to a dynamic distributed multi-channel time division multiple access (TDMA) slot assignment method is presented. The method and apparatus include a set of higher level heuristics that enable the wireless channel access scheme to address predetermined characteristics of the wireless channel access system. These predetermined heuristics include using bootstrap slots, adaptive broadcast cycles, channelized neighborhoods, standby slots, speculation slots, neighbor segregation, hard circuits, and soft circuits.
