| 摘 要： | 为提高多信道无线多跳网络的效用,提出了一种实际可行的跨层优化机制. 利用该机制,每个节点在传输层使用联合设计算法分布式地调整流速率，在链路层根据所提出的分布式调度算法进行速率分配;网关节点使用所提出的干扰代价最小的信道分配算法集中式地分配信道. 通过在层间和节点间传递信息来协调这些层的工作,比集中式算法降低了复杂度，减少了信令开销. 仿真结果表明，该机制具有快速收敛性,且能保证业务流间的公平性；随着可用射频和信道数目的增加,业务流的速率和网络效用增加.

| Abstract: | In order to improve the utilities of the multi-channel wireless multi-hop networks,a practical cross-layer optimization mechanism is proposed. With the proposed mechanism,each node can use joint design algorithm to adjust flow rates distributedly in transport layer,and can use the proposed distributed scheduling algorithm to allocate rates for links in link layer. The gateway uses the proposed minimal interference cost based channel allocation algorithm to allocate channels centralizedly. Through transmitti... |
