%X The flooding method is utilized to forward the acknowledge message to delete the redundant copies of message. As a result, lots of network resources will be consumed by this kind of operation. A novel message deletion mechanism is proposed in this paper. Taking into account the hop count of ACK message, historical forwarding status and regional message density, the ACK message is forwarded to the nodes in the network with the distributed manner to remove the redundant copies of message reasonably. Simulation results show that the redundant copies of message can be deleted with less ACK message by the proposed mechanism; moreover, the network performance can be improved obviously.
