| Abstract: | Aiming at heterogeneous multiple core SoC platform with energy harvesting system in design of wireless sensor networks( WSNs)nodes,a task scheduling and power consumption management algorithm is proposed to improve energy utilization efficiency. The scheduling algorithm is designed to deal with real-time dependent tasks with deadlines and these tasks are executed on variable voltage processing units. After an effective analysis on energy harvesting and application situation,mathematical model for problems are constructed and furthermore the models are resolved by operational research software,LINGO. Multiple group taskflow figure is used to verify that the model and algorithm can definitely effectively improve energy utilization efficiency of system,in restrain range of power consumption and time. |
