摘要:
针对无线传感器网络中不同应用的QoS需求，提出了一种路由协议QMR。该协议使用节点剩余能量、可用缓存以及信道质量等度量值综合评估路径传输可靠性，根据量化的评估值构建自源节点至目的节点的多条路径；并引入路径选取模型，允许数据包依据优先级同时在多条路径上传输；接着采用按通信量更新策略，根据网络流量情况动态调整路由更新频率。通过仿真实验分析得出，该协议在降低网络能耗、提供差别服务方面具有良好的性能
Abstract:
Considering different QoS requirements in different applications, a routing protocol for wireless sensor network named QMR was proposed. The protocol used residual energy ,remaining buffer and quality of channel to estimate the reliability of path. According to the quantizing value of the assessment,multipath from the source node to the destination node could be constructed. A path selection model was introduced to spread out traffic simultaneously across multiple paths by priority after the construction of multipath had been made. Furthermore, the frequency of updating routing information was dynamically set by traffic conditions. According to the simulation results, the protocol achieved good performance in reducing energy consumption and supporting service differentiation
