摘　　要：移动自组织网络中存在暴露节点对信道干扰的问题,因此提出一种分布式信道分配功率算法,用带功率控制的信道分配方式对信道进行自适应调整分配,减少由暴露节点带来的通信干扰,实现节点在移动干扰区内通信,提高移动自组织网络容量。仿真结果表明该算法在保持良好的吞吐量前提下,减少了控制信息开销并减小了传输延迟,实现信道分配最大化,较好地保证了服务质量。In the mobile self-organization network,there is a problem of the interference of the exposed nodes to the channel,and a distributed channel power distribution algorithm is proposed.With the channel distribution method with power control,the channel is adjusted and assigned by adaptive adjustment to reduce the communication interference brought by the exposed nodes.The node can communicate in the mobile interference area and increase the capacity of mobile self-organizing network.The simulation results show that the algorithm maximizes channel availability,reduces control message overhead and ensures good service quality while maintaining good throughput.
