Outage Probability of Energy Harvesting Relay-Aided Cooperative Networks Over Rayleigh Fading Channel

Abstract

Energy harvesting technique is a potential way for relay node energy supply in cooperative networks in the respect of deployment flexibility and maintenance charge reduction. However, unlike traditional power source, it is intuitive that the fluctuation of harvested energy flow can degrade the benefit resulted from relay-aided cooperative transmission. To this end, this paper focuses on the performance analysis of energy harvesting relay-aided cooperative network under slow fading channel from a perspective of outage behavior, and attempts to derive the closed-form expression of outage probability of the proposed cooperative protocol. Compared with simple direct transmission protocol, it is proved that a multiplicative gain for improving system performance in terms of minimizing outage probability can be obtained by energy harvesting relay-aided cooperative transmission. In particular, if there are multiple available relay nodes around the environment or the energyexhausted probability of relay node is small, it is very profitable to employ relay-aided cooperative transmission protocol.

Delay-Constrained Routing Based on Stochastic Model for Flying Ad Hoc Networks

“…Before starting the operation, we first estimate the one-hop delay for node i depending on the remaining delay denoted by T i s . If the neighbor j is selected as a relay by i, the singlehop packet progress [32] to GB is defined as…”

Power Allocation Scheme based on System Outage Probability for Energy-Harvesting Cooperative Networks

“…According to [8], the system outage event in energy-harvesting condition can be caused by two aspects, one is that the energy which is harvested by relay node k R is not enough to forward the information, another is the channel condition of…”

“…The author of [7] proposes a power splitting-based relaying protocol for EH system, which the relay nodes harvest energy from the received signals and use it as the transmit power to forward the signals to the destination node. A two-hop relaying system with direct link and multiple energy-harvesting relays is taken into consideration in [8]. After that, the author gives the close-form expressions for the system outage probability, but the relay power allocation problem is not investigated.…”
