| 摘 要： | 针对ad hoc网络各协议层的功能都相互关联的特点，提出了一种在ad hoc网络中基于网络平均时延最小的跨层自适应流量分配算法（CLATA）。该算法将网络层自适应流量分配信息传递给媒体接入控制（MAC）层，以改进MAC层中的冲突退避算法，实现网络平均时延最小化，提高网络的利用率。仿真实验结果表明，该算法可以动态调整链路之间的流量，并具有快速的自适应性，优化网络资源的利用。

| Abstract: | According to the characteristic that the function of the protocol layers in ad hoc network interconnects,a cross-layer allocation traffic algorithm(CLATA)based on the minimal average time delay in ad hoc network is proposed.The algo- rithm transfers the traffic allocation information from the network to the media access control(MAC)layer in order to im- prove the backoff algorithm on MAC layer,minimize the average time delay in the network and increase the efficient use of network.The resuh of simulation ex... |
