满足业务实时性要求的路由设计

Design of Routing Based on Meeting Service Real-Time Requirements

针对无线传感器网络数据传输实时性问题,基于非均匀分簇网络模型提出了一种路由方法。其主要思想是为收集的数据设定截止期,通过链路时延估计,综合考虑截止期和链路时延等影响接收端接收数据的有效性的因素,提出了一种可以满足多种业务时延要求的路由方法。仿真实验结果表明,该路由方法能够保证信息的有效性。

For wireless sensor networks of real-time data transmission phenomenon, a new routing method is proposed based on the uneven cluster network model. Through setting deadline for collecting data,estimating link delay and considering the factors influencing the validity of receiver’s receiving data such as the deadline of information,link delay,etc,a new routing method fit for multi-service delay requirements is proposed. Simulation results show that the routing method can ensure the validity of the information.
