Reactive Opportunistic Hybrid Relaying Protocol for Two-way Relaying Communication Systems

We investigate the performance of reactive opportunistic hybrid relaying protocol for two-way relaying communication systems. Many previous works focus on the proactive opportunistic relaying, reactive opportunistic two-way relaying and reactive opportunistic one-way relaying. This work investigates the possibility of combining two-way and one-way relaying for two-way communications. In this work, the outage performance of opportunistic hybrid two-way and one-way relaying protocol is derived and the simulation validates its correctness. From the simulation, we find that the reactive opportunistic hybrid relaying works better when the number of relays is small or when the relays has very limited transmission power such as IoT devices and sensors.
