Disclosed herein are systems and methods for enhancing wireless message throughput at high traffic density and high interference rates, by use of a managed message transmission protocol in which the base station instructs each node to transmit or retransmit a DAT message. For example, the base station may determine which node has experienced the most delays and may grant that node permission to transmit immediately, while instructing other nodes to wait their turn. Protocols can provide, under control of the base station, prompt mitigation and message completion after messages are corrupted by interference. The average delays, collision rate, and failure rate may be substantially reduced while the success rate and uniformity of access may be substantially improved. The managed transmission protocols can be incorporated in current and planned systems by software updates at low cost, while retaining the ability to receive and process messages from legacy nodes transparently, according to some embodiments.
