基于带状区域路由的无线传感器网络QoS协议

QoS Routing Protocol for Wireless Sensor Networks Based on Strip of Area

提出了一种基于带状区域路由的无线传感器网络QoS协议。根据网络传输路径的能耗模型分析,将路由的转发节点控制在以源节点与Sink节点连线的带状区域,有效降低了路径上的传输能耗。另外,在改进型QoS协议中,转发节点根据当前QoS约束动态重新建立新的带状区域宽度,使传输路径最大程度拟合源节点和Sink节点的连线,达到路径传输能耗最优。仿真实验表明,无线传感器网络QoS协议在满足网络QoS约束下,节省了网络能耗,延长了网络生存时间。

A QoS routing protocol for wireless sensor networks based on strip of area was proposed. According to analy- sis of the network transmission path energy consumption model, the forward routing nodes were controlled in strip of area of the straight line between source node and sink node, effectively reducing the transmission energy consumption on path. In addition, in the improved QoS protocol, the forward nodes dynamicly established the width of strip of area ac- cording to the current QoS constraints, so that the routing path most fits the straight line between source node and sink node to achieve the purpose of optimising the path transmission energy consumption. Simulation experiments show that the QoS protocol for wireless sensor networks, at meetting the networks QoS constraints, saves network energy con- sumption and prolongs survival time of the network.
