This paper addresses the limitations of existing interest forwarding strategies in Named Data Networks (NDN) over Low-power and Lossy Networks (LLNs). While current strategies utilize listening periods to minimize duplicate retransmissions, they suffer from indiscriminately propagating interests across the network, resulting in excessive retransmissions. Conversely, strategies with propagation control often neglect challenges posed by producer mobility. In response, we propose an efficient forwarding strategy that not only mitigates duplicate retransmissions but also governs interest propagation through the integration of probabilities and estimated distances to data producers. Additionally, the strategy adeptly manages producer mobility through judicious flooding control. In contrast to prior studies primarily benchmarking against Blind Flooding (BF) and Deferred Blind Flooding (DBF), our work presents the first comprehensive evaluation of the new forwarding scheme against six established strategies. Through extensive simulations, we demonstrate the superiority of our proposed forwarding solution across key performance metrics, including sent packets, retrieval latency, success rate, and energy consumption in various scenarios.
