为了应对传统自组织网络高度动态拓扑、短寿命连接等特性导致的传输失效问题,基于命名数据网络(NDN)架构,设计了一种联合链路稳定性和内容可达性的可靠转发(RF-LSCA)策略。该策略基于多属性决策方法,综合考虑链路持续时间、节点间距离和内容可达性3个关键属性,从而更加精确地选择最优转发节点,提升了内容传输性能;此外,鉴于单一最优路径可能存在的不稳定性,该策略进一步将决策模型与概率转发思想相结合,设计了兼具低开销与高可靠性的冗余转发机制。这一设计充分利用了NDN的多路径特性,以保障移动环境下的内容传输性能。通过仿真实验验证,所提RF-LSCA在内容获取平均时延、平均跳数、内容满足率等多个关键性能指标上优于现有策略,充分证明了其在提高NDN-Ad Hoc网络传输效率方面的优越性。
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.
