The Study of Sensor Network Routing Algorithm Based on Task Delay and Priority

提出了一种基于任务延迟的和优先级的传感器网络QoS路由机制.该路由机制对传感器网络的传输的数据和执行的任务划分优先级,根据每个数据所标识的优先级不同,路由转发的次序也不同.高优先级的任务数据比低优先级的任务数据先被转发,从而确保传感器网络总体的转发效率处于较高数值.仿真结果表明,新算法能够实现不同任务延迟要求的数据自动划分优先级,有序地发出,算法具有简单、稳定、收敛速度快的特点.

This paper Proposed one kind of sensor network QoS route mechanism based on the task delay and priority. The route mechanism division priority according to the difference of the sensor network transmission data and the execution task. the priority which marks according to each data is different, the route retransmits order is also different. The high priority mission data is retransmitted first compared to the low priority mission data, thus guaranteed that the sensor network overall the repeater efficiency is in the high value. The simulation result indicated that the new algorithm can realize the different task detention request data automatic division priority, and sends out all data in the order, besides that the algorithm has simply, stable, the convergence rate quick characteristic.
