| 摘 要： | 提出一种基于动态树冲突分解的协作随机接入方案(DTCRA)。该方案设置一个由冲突节点个数决定的信道增益门限值,若源节点与接入点间的信道增益大于该门限值,则源节点重传数据包,否则由中继节点放大转发,从而实现了动态树冲突分解,获得了多用户分集增益并降低了空时隙数量。数值与仿真结果表明,提出的方案相比于其它传统类和跨层类随机接入方案,具有更好的吞吐量、时延和能量效率性能。 |

| Abstract: | A novel cooperative random access scheme based on dynamic tree collision resolution (DTCRA) was proposed.This scheme sets up a threshold determined by the number of collided nodes.If the channel gain between source node and access point (AP) is bigger than this threshold,source node will resend data packets,otherwise relay nodes will amplify and forward the data packets.Therefore,dynamic tree collision resolution is carried out,multi-user diversity gain is achieved and the number of empty slots is also decr... |
