Abstract
A system and method for managing acknowledgments and retransmissions in a distributed manner in a MANET with 2-hop clustering structure. Clusterheads are in charge of assuring delivery of flooding packets to their members. After receiving acknowledgments from associated nodes in the cluster, and clusterheads perform retransmission when necessary with a list of acknowledging nodes. The non-clusterhead nodes receive the retransmissions and determine if that node's acknowledgment was received based on a list of node IDs included in the retransmission. If the node ID is not listed, the node resends the acknowledgment. The process continues until all acknowledgments are received and listed.
