Transmission Policies for Energy Harvesting Sensors Based on Markov Chain Energy Supply

Due to the small energy harvesting rates and stochastic energy harvesting processes, energy management of energy harvesting senor is still crucial for body network. Transmission polices for energy harvesting sensors with Markov chain energy supply over time varying channels is formulated as an infinite discounted reward Markov Decision Problem under the assumption of geometric distribution of s...

Structural Properties of Optimal Transmission Policies for Delay-Sensitive Energy Harvesting Wireless Sensors

We consider an energy harvesting sensor transmitting latency-sensitive data over a fading channel. We aim to find the optimal transmission scheduling policy that minimizes the packet queuing delay given the available harvested energy. We formulate the problem as a Markov decision process (MDP) over a state-space spanned by the transmitter’s buffer, battery, and channel states, and analyze the s...

Optimal Transmission Policies for Multi-hop Energy Harvesting Systems

In this paper, we consider a multi-hop energy harvesting (EH) communication system in a fullduplex mode, where arrival data and harvested energy curves in the source and the relays are modeled as general functions. This model includes the EH system with discrete arrival processes as a special case. We investigate the throughput maximization problem considering minimum utilized energy in the sou...

Optimal Transmission Policies for Energy Harvesting Transmitter with Hybrid Energy Source in Fading Wireless Channel

Optimal energy scheduling problem for single-user wireless communication system in fading channel is studied in this paper. In this schedule, the transmitter is powered by hybrid energy sources including both the conventional grid and an energy harvester collecting energy from nature and storing energy in a rechargeable battery. In this system, data arrival process, energy harvesting process an...

Sensors for Energy Harvesting System

A considerable attention has been given to the energy harvesting system, as the energy obtained from this system is used for powering up small electronic devices instead of using batteries. Battery manufactures make batteries of required size with long life of usage. However, it is difficult to replace such batteries once its life is expired. This difficulty can be partially overcome by using t...
