Energy Allocation Algorithm for Energy Harvesting Wireless Sensor Network

the life-time of wireless sensor network can easily be prolonged very significantly, with the
use of energy harvesting technologies. The energy management policy of an energy harvesting WSN
take into account the energy replenishment process, unlike a traditional WSN powered by nonrechargeable
batteries. In this paper, we present a study about the energy allocation for transmission
and sensing in an energy harvesting sensor node with a finite buffer and rechargeable battery. The
aim of the sensor node is to maximize the total data transmitted in a finite horizon subject to channel
fading, energy harvesting rate and energy availability in the battery. Here in this paper we present a
energy distribution algorithm using dynamic programming for energy allocation problem. We
conduct simulations to compare the performance between our proposed algorithm and the existing
algorithm from[1]. Simulation results show that the proposed algorithm achieves a higher
throughput than the existing algorithm under different settings.
