| 摘 要： | 基于无线传感器网络服务质量(QoS)的特点，提出了一个独立于具体算法的、在点和边上都可加权的有向图网络模型，并用数学定义描述了QoS参数间的关系及服从的函数约束，使用该网络模型分析QoS路由的数学约束集并提出QoS路由选择策略。

| Abstract: | According to the characteristics of quality of service(QoS) in wireless sensor networks(WSNs),a network model is proposed based on directed graph in which the vertexes or edges of the graph have their weights that denote the relationship and the function constraints of the QoS metrics.The model is independent of any algorithms.The relationships and the function constraints of the parameters are defined in mathematics.By using this model,the QoS routing is analyzed,the mathematics constraints set and the routing strategies of the QoS routing in WSNs are presented. |
