Abstract
Cooperative communication is a promising technique to improve utilization of the wireless spectrum resource. However, due to the limited wireless network resource, the selfish relay nodes may be unwilling to offer their relay help without any extra incentive. In this work, we study a contract-based mechanism for incentivizing cooperative relay in the presence of the dual asymmetric information. By modelling multi-user cooperative relay as a labour market, a principal-agent model is proposed with the combination of relay power, basic wage and relay bonus in the continuous type scenario. And an optimization problem of multi-user relay incentive is formulated to achieve the twin objectives of ability-discrimination and effort-incentive. Numerical results show that the optimal contract design scheme is effective in improving the performance of cooperative communication.
