Network coding, as one of the foremost techniques boosting the performance of the wireless networks, has recently acquired notable popularity. As a result, a new category of routing approaches named as the coding-aware routing scheme, has been emerged. In such routing schemes, the possible coding opportunities are identified prior to the path establishment, and paths containing coding opportunities are prioritized to be established. Motivated by the appreciable efficiency of the coding-aware routing schemes, this paper leverages fuzzy logic and proposes a novel coding-aware routing approach alluded to as Fuzzy-logic-based Network Coding-aware Routing (FNCR) protocol. Notwithstanding a number of previously proposed coding-aware routing schemes which merely endeavor to establish paths including more coding opportunities, FNCR suggests embedding a purposefully designed fuzzy system in each node in order to calculate the overall desirability of the nodes in terms of some momentous factors such as the coding capability, the remaining energy, and the workload of the node. In addition to a new routing metric which utilizes the calculated overall desirability, the previously proposed coding conditions are modified such that more possible coding opportunities can now be identified. Simulation results demonstrate that FNCR outperforms the formerly proposed approaches employing network coding, in terms of throughput, end to end delay, packet delivery ratio, and lifetime of the network.

在无线自组织网络中结合基于模糊逻辑的转发器的分布式网络编码感知路由协议

网络编码作为提高无线网络性能的最重要技术之一，最近获得了显着的普及。因此，出现了一类新的路由方法，称为编码感知路由方案。在这样的路由方案中，可能的编码机会在路径建立之前被识别，并且包含编码机会的路径被优先建立。受编码感知路由方案的显着效率的启发，本文利用模糊逻辑并提出了一种新的编码感知路由方法，被称为基于模糊逻辑的网络编码感知路由 (FNCR) 协议。尽管许多先前提出的编码感知路由方案仅努力建立包括更多编码机会的路径，FNCR 建议在每个节点中嵌入一个有目的设计的模糊系统，以便根据一些重要因素（例如节点的编码能力、剩余能量和工作负载）来计算节点的整体合意性。除了利用计算出的整体合意性的新路由度量之外，还修改了先前提出的编码条件，以便现在可以识别更多可能的编码机会。仿真结果表明，FNCR 在吞吐量、端到端延迟、数据包传输率和网络寿命方面优于以前提出的采用网络编码的方法。剩余能量，以及节点的工作负载。除了利用计算出的整体合意性的新路由度量之外，还修改了先前提出的编码条件，以便现在可以识别更多可能的编码机会。仿真结果表明，FNCR 在吞吐量、端到端延迟、数据包传输率和网络寿命方面优于以前提出的采用网络编码的方法。剩余能量，以及节点的工作负载。除了利用计算出的整体合意性的新路由度量之外，还修改了先前提出的编码条件，以便现在可以识别更多可能的编码机会。仿真结果表明，FNCR 在吞吐量、端到端延迟、数据包传输率和网络寿命方面优于以前提出的采用网络编码的方法。
