Reliable forwarding strategy based on multiple attribute decision-making in NDN-Ad Hoc networks

To address transmission failures in traditional Ad Hoc networks, which was caused by highly dynamic topologies, short-lived connections characteristics, a reliable forwarding strategy based on link stability and content accessibility forwarding (RF-LSCA) based on the named data networking (NDN) architecture was designed. A multi-attribute decision-making method was utilized as the foundation for this strategy, with consideration given to link duration, distances between nodes, and content accessibility. This enabled a more precise selection of the optimal forwarding node, thereby enhancing the content transmission performance. Furthermore, given the potential instability of a single optimal path, the decision model was combined with probabilistic forwarding to design a low-overhead yet highly reliable redundant forwarding mechanism. The full exploitation of NDN's multipath characteristics was achieved through this design, thereby ensuring content delivery efficiency in mobile scenarios. Through simulation experiments, the proposed RF-LSCA is demonstrated to outperform existing strategies in key performance metrics, including average content retrieval delay, average hop counts, and content satisfaction rate. These results provide ample evidence of its superiority in enhancing transmission efficiency within NDN-Ad Hoc networks. © 2024 Editorial Board of Journal on Communications. All rights reserved.
