Optimal Resource Scheduling for Energy Harvesting Communications under Strict Delay Constraint

Fawaz Ibrahim; Sarkiss Mireille; Ciblat Philippe

This paper investigates the resource scheduling minimizing
the packet loss when the wireless communication system
operates with Energy Harvesting (EH) based devices. The packet
loss occurs when the buffer is overflowed and when the queued
packet is older than a certain pre-defined threshold. We so
consider a strict delay constraint rather than an average delay
constraint. The associated optimization problem can be modeled
as Markov Decision Problem (MDP) where the actions are the
number of packets sent on the known channel at each slot. The
optimal deterministic offline policy is exhibited through dynamic
programming techniques, i.e. Value Iteration (VI) algorithm. We
show the gain in the number of transmitted packets and the
consumed energy is substantial compared to a naive policy which
forces the system to send the maximum
