| Summary: | Energy harvesting network (EHN) is a trending
topic in wireless communications that enables wireless devices to
harvest energy from ambient sources such as RF waves.
However, EHN faces energy causality constraint that turns the
energy harvester into sleep mode. This, in turn, delays the
processing of next task until harvesting the required energy for
processing. The objective of this research is to prolong the active
mode of energy harvesters by employing a novel scheme of EHN
that combines local computing and wireless distributed
computing in one EHN. Accordingly, a novel EHN algorithm that
employs partially observable Markov decision process (POMDP)
is proposed in order to automate the decision of the energy
harvester based on the channel variations and stored energy.
Herein, the scheme of the proposed EHN is explained first. Then,
the problem of the proposed EHN is formulated as POMDP.
Furthermore, a policy is found in order to estimate the validity of
the proposed EHN against the conventional EHN. |
