Abstract:

In order to eliminate extra interferences during the relay transmission in large-scale wireless networks,a combined relay selection and power control algorithm is proposed based on the interference model. In this algorithm,with the help of the defined interference coefficient and the interference list for the relay node,the relay with the maximum interference coefficient is selected to adjust the power of the relay in each iteration. Thus,a noninterference relay with the largest capacity is obtained. Simulated results indicate that,as compared with the relay selection algorithm without interference consideration or with interference avoidance,the proposed algorithm possesses larger network capacity and is more effective when there is serious interference.

Key words: cooperative communication, relay selection, power control, interference avoidance
