Sensor Network Routing Algorithm Research Based on Task Delay and Priority

The paper has proposed the QoS route mechanism of the sensor network based on task delay and priority. The new control mechanism assigns the network resource proportionately according to the different priorities of tasks. The tasks with a higher priority can obtain more network resource in respect to the tasks with a lower priority, which will guarantee that the information of task occurrence can be transmitted to sink node quickly and accurately. The simulation result has indicated that the new algorithm can divide the packet priority for different tasks according to different request of delay time automatically, and then send it out with different priority. In a word, the algorithm has the characteristics of simplicity, stability, and quickly convergence.
