ABSTRACT:
The present invention is a system and method for providing conflict resolution for broadcast slot assignments. Method may include receiving a message from at least two nodes. Method may determine from received messages that at least two other nodes in a network have elected to transmit in a single broadcast slot. Method may determine individual node identifier information for each of a second and third node. Method may arrange a second and third node in an order based on individual node identifier information determination. Prior to the completion of a bootstrap cycle, method may select which of a second or third node may utilize the desired broadcast slot based on the arranged order for each of the second and third node. Method may broadcast a node selection to all nodes in a network.
