中文摘要：
基于传感器节点的地理位置信息与网络传输路径的能耗模型分析,提出一种无线传感器网络服务质量（QoS）路由算法.将多跳传输路径中的转发节点序列控制在以源节点与汇聚节点连线的一定区域内,尽量拟合源节点与汇聚节点连线传输,有效控制了传输路径.并对QoS路由算法提出改进,转发节点根据当前实时QoS约束动态地调整传输区域的大小以及优化下一跳选择机制,使传输路径最大程度拟合源节点和汇聚节点之间的连线,达到路径传输能耗最优.仿真实验表明,该QoS路由算法在满足网络QoS约束的同时,节省了网络的能耗,延长了网络生存时间.
英文摘要：
Based on sensor node＇s geographical location information and energy consumption model analysis of network transmission path,this paper proposed a QoS routing algorithm for wireless sensor networks,which will control the forward nodes sequence of multi-hop transmission path in the source node and sink node connection area,to fit the source node and sink node connection transmission,and effectively control the transmission path.The paper also proposed to improve the QoS routing algorithm,by which the forward nodes can dynamically adjust the size of transmission path area based on the current real-time QoS constraints and optimize the next hop selection mechanism,so that the routing path can maximize the fitting of the straight line between source node and sink node to achieve the optimal path transmission energy consumption.The simulation experiments show that the QoS routing algorithm for wireless sensor networks can achieve the network QoS constraints,while save the network energy consumption and prolong the network life.
