%X Considering the characteristic of message forwarded in the spray and wait routing, this paper presented that a node will drop the delivered messages depending on ACK exchange mechanism to reduce the transmission of redundancy messages in the network. When the buffer of a node was fully occupied and it needs to store new messages, the node would start congestion detection and congestion avoidance. It would lookup per message in its buffer, and drop the message whose number of copies was least (if this message was being sent, the message of second least copies was returned) until the buffer has enough space to store new received messages. By the analysis and comparison of the related data in a large amount of simulation experiments, it demonstrates that this congestion control strategy can significantly enhance delivery utility and reduce the overhead, and be better adaptive to the congestion.
