RETRACTED: An efficient energy harvesting scheme to maximize the throughput of the wireless relay network with TSR and PSR protocol

Delay constrained No delay constrained Power splitting relay protocol Time switching relay protocol Decode and forward relay a b s t r a c t Energy management techniques are significant for upcoming new generation networks to increase the lifetime of the network. An energy harvesting (EH) device converts different form of environmental energy to electricity and supplies to the intermediate nodes in the network. In this paper, an efficient energy scavenging scheme is proposed in multiple relay network, where the users cooperate each other to deliver the data to destination. Here, decode and forward (DF) relay protocol is considered in which the intermediate relay node acts as an energy harvesting device which receives signal from the source, scavenges energy from the environment and uses this energy to forward the information from source to destination. In the proposed work, first serial topology model is considered. The throughput maximization problem is formulated at individual user and relay using power splitting relay (PSR) and time switching relay (TSR) protocols. Second, the above problems are formulated in parallel topology model. Here, wireless network with three relay nodes are considered under two different traffic conditions: delay constrained (DC) and no delay constrained (NDC). Further, DC and NDC results are compared where NDC outperforms DC traffic conditions. Simulation results show that the throughput obtained via PSR protocol is larger compared to TSR protocol. Also, with the increase in number of EH nodes between source and destination throughput and life time of the network increases which finds application in 5G networks. Structural realization and analysis pertaining to power and throughput are implemented in MATLAB. © 2015 Elsevier GmbH. All rights reserved.
