| Abstract | We consider a system of two user terminals, both of which is capable of acting as a relay station for each others’ sake. We consider a simple scenario where the user equipment that acts as an amplify-and-forward relay station tries to sell its data rate at some fixed price to the user equipment that acts as a source station. The benefit the source station receives is equal to achievable data rate obtained from maximal ratio combining minus the data rate it buys from the relay station, converted into monetary value. The cost of cooperation for both the stations is reflected by their power consumption, which both of them want to reduce. This conflicting goal of increasing the revenue, while at the same time, decreasing the cost, by both the users, is studied using game theoretical modeling. The situation is modeled as a symmetric, two person bargaining game. The solution of such a game is unique and Pareto optimal. We derive the conditions for which the bargaining cooperation will succeed. The cooperation will take place so long the conditioned are fulfilled. We obtain explicit solutions for the transmitted power from the source and from the relay. In simulation, we use Matlab program and plot to compare the performance of utility for bargaining that results in cooperation and non-cooperation. We also simulate our system with bargaining power to obtain bit error rate with BPSK modulation. The result shows that bit error rate from our system matches with theoretical result. |
