Abstract： To enhance the quality of service （QoS） in named data mobile ad hoc network （NDMANET），this paper proposes a novel node activeness-based packet forwarding （NAPF） strategy designed to mitigate performance degradation caused by the network’s time-varying topology. The proposed NAPF strategy periodically calculates andupdates the activeness levels of all participating nodes，prioritizing nodes with higher activeness for forwarding and caching interest and data packets.A simulation platform is developed using the open-source NS-3/ ndnSIM framework to conduct comparative performance evaluations among default flooding，shortest path routing，and the proposed NAPF strategy. Experimental results indicate that in medium-to high-mobilityscenarios， the NAPF strategy significantly reduces average request delay，improves response ratios，and decreases bandwidth consumption， with only a modest increase in node storage usage.
