现有的路由算法不能有效地支持无线传感器网络的动态特性，不能保证无线传感器网络应用的服务质量。提出了一种基于代理辅助的无线传感器网络QoS路由算法。该算法以无线传感器网络的综合服务质量作为粒子群优化算法的自适应值，提高网络的整体性能。智能软件代理用于监控网络拓扑、网络通信流和每个节点的路由状态的变化。然后，这些代理可以参与网络路由和网络维护。实验结果表明，与传统算法相比，该算法能保证无线传感器网络更好的服务质量。
Existing routing algorithms are not effective in supporting the dynamic characteristics of wireless sensor networks (WSNs) and cannot ensure sufficient quality of service in WSN applications. This paper proposes a novel agent-assisted QoS-based routing algorithm for wireless sensor networks. In the proposed algorithm, the synthetic QoS of WSNs is chosen as the adaptive value of a Particle Swarm Optimization algorithm to improve the overall performance of network. Intelligent software agents are used to monitor changes in network topology, network communication flow, and each node's routing state. These agents can then participate in network routing and network maintenance. Experiment results show that the proposed algorithm can ensure better quality of service in wireless sensor networks compared with traditional algorithms.
