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。 Aiming at the characteristics that each protocol layer in ad hoc networks are interrelated, this paper proposes a cross-layer adaptive traffic allocation algorithm (CLATA) based on minimum network average delay in ad hoc networks. The algorithm transfers network-layer adaptive traffic allocation information to the media access control (MAC) layer to improve the collision avoidance algorithm in the MAC layer to minimize the average network latency and improve network utilization. Simulation results show that the algorithm can dynamically adjust the traffic between links and has fast adaptability to optimize the utilization of network resources.
