According to one aspect, embodiments of the invention provide a node comprising a processor, a memory including a predefined mapping, the predefined mapping correlating network characteristics to related critical thresholds at which a delivery ratio of the node is close to a maximum level and at which a total number of transmissions by the node is close to a minimum number necessary to achieve the delivery ratio, and a component configured to communicate with one-hop neighbors of the node and configured to determine at least one characteristic of a dynamic network based on information received from the one-hop neighbors of the node, wherein, in reference to the predefined mapping, the processor is configured to identify a critical threshold associated with the at least one characteristic of the network and is configured to transmit a first packet to at least one one-hop neighbor based on the critical threshold.
