Outline of Final Research Achievements

Data processing and available energy heavily depend on environments in widely distributed sensing and computing systems. This research proposed execution model which optimize data processing both in temporal and spatial in such systems. Firstly, in case that processing time of task is determined during computation, task scheduling algorithm is proposed to minimize energy consumption while satisfying performance constraints. Its superiority to other existing methods is successfully shown. Secondly, in solar energy harvesting sensor node systems, an adaptive power manager is proposed by using reinforcement learning. The proposed manager successfully achieves higher performance without increasing wasted energy regardless the location of sensor nodes.
