The furthermost important issues in WSN are to provide a multi-path and multi-constraint Qualify of Service (QoS) routing for uninterrupted communications between the nodes. On one hand, multi-constrained QoS routing deals with identifying paths that assure numerous autonomous QoS limitations, and on the other hand, multi-path refers to the identification of multiple paths. The EB-RRTC (Energy based random repeat trust computation) algorithm is employed for encountering trusted nodes with destination node. The proposed method also employs the Reliable Fuzzy and Heuristic Concurrent ACO (RF-HEACO) QoS Routing Protocol to improve QoS. The HEACO-RF QoS Routing Protocol includes two phases. In the first phase, the Ant Colony Optimization algorithm is modified to identify a deposit of candidate routes among a pair of source and destination. While identifying the candidate routes along with the QoS metrics, heuristic factors and Reliable Fitness Functions are considered. In the second phase, the reliability technique is used to measure each path, and the paths with high reliability is selected by the ant agents using Fuzzy logic based on the metrics link stability, residual energy, and packet loss rate. Simulation outcomes prove that RF-HEACO QoS routing protocol can decrease the energy consumption and improve the packet delivery ratio, and packet loss rate with the minimum delay when compared with the techniques. In other words, our method is well capable of offering improved QoS (Quality of Service).

基于能量的随机重复信任计算方法和可靠的模糊和启发式蚁群机制，用于提高 WSN 中的 QoS

WSN 中最重要的问题是为节点之间的不间断通信提供多路径和多约束服务质量（QoS）路由。一方面，多约束QoS路由涉及识别确保众多自治QoS限制的路径，另一方面，多路径指的是多条路径的识别。EB-RRTC（基于能量的随机重复信任计算）算法用于与目标节点相遇可信节点。所提出的方法还采用可靠模糊启发式并发 ACO (RF-HEACO) QoS 路由协议来提高 QoS。HEACO-RF QoS 路由协议包括两个阶段。在第一阶段，修改蚁群优化算法以识别一对源和目的地之间的候选路线的存储。在确定候选路由以及 QoS 指标时，会考虑启发式因素和可靠的适应度函数。在第二阶段，使用可靠性技术测量每条路径，蚂蚁代理根据链路稳定性、剩余能量和丢包率等指标，使用模糊逻辑选择可靠性高的路径。仿真结果证明，与现有技术相比，RF-HEACO QoS路由协议能够以最小的时延降低能耗，提高数据包送达率和丢包率。换句话说，我们的方法能够很好地提供改进的 QoS（服务质量）。
