| 摘 要： | 针对用户设备电池寿命有限的问题,提出了一种基于分簇的资源分配机制。该机制结合图着色原理对D2D用户分簇；随后根据分簇结果,采用拍卖算法为D2D簇分配信道；利用非合作博弈论模型对完成信道分配的用户进行功率分配。仿真结果表明,该机制有效地延长了电池寿命,提升了用户的能量效率,同时满足了用户传输速率的需求,保证了用户获得更高的QoS。

| Abstract: | A cluster-based resource allocation mechanism was proposed for the problem of the limited battery life of the user equipment.The mechanism includs three parts:D2D users are put in disjoint clusters by graph theory,and then the auction algorithm is used to allocate the channel for D2D clusters according to the clustering results.In the end,the power allocation is performed by using non-cooperative game theory model.Simulation results show that the proposed mechanism effectively extends battery life,improves the energy efficiency of the users,and satisfies the requirements of the user transmission rate,thus ensuring the users to obtain higher QoS. |
