In Named-Data Mobile Ad Hoc Network (NDMANET), the routing node uses the flooding forwarding strategy by default. When multiple producers receive the same data request, they will return multiple identical data packets, but the consumer only needs to receive one of them to meet the demand, and the rest of the data packets are redundant. The transmission of many redundant data packets on the network will significantly occupy network bandwidth resources. To solve this problem, this paper designs a data packet forwarding strategy suitable for NDMANET named Reduce Redundant Data Packets (RRDP) strategy, which aims to make redundant packets stop forwarding at the intermediate node. This strategy can reduce the transmission of redundant packets and minimize network traffic as much as possible on the premise of keeping the successful rate of consumer requests basically unchanged. This strategy is relatively simple and has a low implementation cost, so it is more suitable for NDMANET with small node storage space and limited computing capacity.
