An Optimized Distributed Routing Protocol for Energy Management Systems Based on Wireless Sensor Networks in Intelligent and Smart Structures

Energy and spectrum efficiency for energy management systems based on wireless sensor networks in intelligent structures powered by ambient harvesting (EH) are the main problems networks. Herein, we consider relay selection methods. To address this issue, proposed optimal multiantenna power beacon opportunistic (OMPB-ORS) protocol, which uses decoding forward methods, nodes second source energy-restricted can harvest from a (PB) to transmit aggregated information data destination. The protocol specific s witching t ime r eceiver rchitecture e nhances nd-to-end p erformance f or m aximum h ardware impairments interference transceiver. evaluate performance, compared our with best ORS (B-ORS), conventional (C-ORS), hybrid partial (H-PRS) protocols. Using Rayleigh-fading channel, simulation is driven asymptotic exact form expressions of throughput (TP) outage probability (OP). Simulation results show that OMPB-ORS achieves higher TP OP than all
