传感器

Supposing processing information as a task of node,power constraints of node is considered,and node uses way of awaking/sleeping,during awaking assureed that sensor node accomplishes task and cluster head node can schedule multi-task of sensor node.will resolve such problem:before satisfying multi-tasks deadline invaliding of sensor node,how to feasibly schedule schedule algorithm of improving Rate-Monotonicand dynamic Preemptive Earliest Deadline First Algorithm,via concrete example are presented,The process of algorithm achieving is explained.

假定每个节点对信息的处理看作是一个任务，考虑节点能量限制，节点采用唤醒/休眠机制，在唤醒期间确保节点任务完成，簇头节点能够调度处理多个传感器节点的任务。文中解决的问题：在满足多个传感器节点任务处理的截止期失效前，簇头节点如何合理的调度任务，提出了改进的 RM(rate-monotonic)调度算法和动态的抢占式最早截止期优先任务调度算法(Preemptive Earliest Deadline First Algorithm，PEDFA)。
