Abstract

In directional energy transmissions, a radio frequency (RF) energy source needs to monitor each sector to achieve higher RF energy transmission efficiency. However, since the distribution of harvesting nodes can be dynamically changed in mobile environments, it is difficult to obtain the exact numbers of harvesting nodes in all sectors within limited time. In such a situation, the operations of RF energy sources (i.e., monitoring the number of harvesting nodes and transmitting the RF energy) can be modeled by a partially observable Markov decision process (POMDP), which has high complexity to be solved. As a practical solution, in this paper, we propose an observation-based directional energy transmission algorithm (OB-DETA) that estimates the population in sectors and transmits the RF energy to the selected sector with a sufficient number of harvesting nodes. Evaluation results are given to demonstrate the effectiveness of OB-DETA over the comparison schemes in terms of the RF energy transmission efficiency.
