为了充分地利用网络资源
提出了一种分群结构下的无线传感器网络多轮任务调度算法(WMTSA).WMTSA以可分负载理论为基础
根据各个群的任务处理速率按多轮方案将总任务从SINK节点下发给各个群.为了去除由节点间通信干扰导致的性能下降
SINK节点相继向各个群首发送每一轮的负载.每一轮各个群执行完数据采集任务并把数据融合后
也由群首将该轮数据相继向SINK节点报告
使得任务执行和通信更好地重叠
最终减少了整个应用的响应时间且提高了网络资源利用率.实验结果表明
WMTSA可合理地将总任务分配给网络中的各个节点
从而有效地减少了完成任务的耗时耗能.随着网络规模的增大
总任务完成时间可以减少40%.
A multi-round task scheduling algorithm(WMTSA)under clustering structure in wireless sensor networks is proposed to fully use the network resources. The WMTSA is based upon the divisible load theory and the tasks in SINK are distributed to every cluster head by multi-round according to the processing capacity of each cluster. The SINK sends tasks of each round to cluster head sequentially to remove performance degradation caused by communications interference. After each cluster finishing its tasks and fusing the data
the cluster heads send results of the round back to the SINK sequentially. The proposed algorithm could overlap the task-performing and the communication phase much better
reduce task completion time
and improve network resource utilization. Simulation results show that the algorithm enables tasks to be reasonably distributed to each node in wireless sensor networks
and effectively reduces both time-consuming and energy-consuming in completing tasks. It is found that with increasing size of networks
the task completion time is reduced by 40%.
