Abstract/Description
Relaying in wireless communication can improve power and quality of service. Multiple nodes share channel resources to achieve optimized power. We consider a model with fixed source, destination and relay nodes. Our model finds the optimal values for power transmission for direct and relayed transmitting nodes. In our problem we compare amplify and forward and decode and forward transmission protocols. Unlike other researchers who use constant achievable rates as objective function and power as constraint, we use the strategy of minimizing relay and source power with achievable and target rates as constraints. We simulate various scenarios and our results indicate optimal values for both source and relay transmission powers.

Application of ICT - I: Power optimization of relay channels
Relaying in wireless communication can improve power and quality of service. Multiple nodes share channel resources to achieve optimized power. We consider a model with fixed source, destination and relay nodes. Our model finds the optimal values for power transmission for direct and relayed transmitting nodes. In our problem we compare amplify and forward and decode and forward transmission protocols. Unlike other researchers who use constant achievable rates as objective function and power as constraint, we use the strategy of minimizing relay and source power with achievable and target rates as constraints. We simulate various scenarios and our results indicate optimal values for both source and relay transmission powers.
