A Hybrid Protocol for SWIPT in Cooperative Networks

A promising technology for addressing network lifetime and energy bottlenecks in wireless networks is the Simultaneous Wireless Information Power Transfer (SWIPT). In this paper, a Hybrid Time switching splitting-based Relaying (HTPR) protocol SWIPT an Amplify-and-Forward (AF) proposed. The consists of source, relay, destination which relay performs Energy Harvesting (EH) from source signal uses harvested to transmit destination. direct link exists between destination, signals are combined by Maximum Ratio Combining (MRC) method at Closed-form expressions outage probability derived under delay-limited transmission determine achievable throughput different schemes. For constant data rate, HTPR with uniform optimal EH ratios considered maximization. To solve optimization problem, convex technique Lagrange multiplier Karush-Kuhn-Tucker (KKT) conditions used. Results show that has higher than other protocols relatively high Signal-to-Noise (SNR).
