Simulation Results

In order to combat multi-path fading across multiple protocol layers in the wireless networks effectively, cooperative diversity is developed with a virtual multi-antenna array, and spatial diversity can be achieved with the relaying. In this paper, we study an improved opportunistic relaying which could be applied to future Internet of Things. Simulation results shows it has better outage probability and spectral efficiency, and based on the model we propose a simplified power allocation method, which has close performance to the exhaustive search method. It has less calculation complexity and lower outage probability, which would be more applicable for future cooperative systems.
