【摘要】：航空自组网(AANET)是一种节点高速运动、网络拓扑持续快速变化的新型自组织网络。针对AANET的特点,提出了一种新的时分多址(TDMA)时隙分配方法。首先,根据高动态航空网络环境中媒体访问控制(MAC)协议的特点,推导出可以共用一个时隙进行通信的连接集合的计算方法,并建立了面向连接的空间复用TDMA(STDMA)时隙分配优化数学模型。然后,提出一种分布式STDMA时隙分配算法IDTA。IDTA不需要中心节点收集网络信息,分为2个同步的进程在发送节点和接收节点同时运行,而且能够根据连接的优先级按需分配时隙。最后,在OMNeT++仿真平台上建立计算机仿真模型,仿真结果显示:IDTA比其他分布式STDMA时隙分配算法更加适用于高动态的航空网络环境。
[Abstract]:Aeronautical Ad Hoc Network (AANN) is a new type of ad hoc network with high speed movement of nodes and continuous and rapid changes in network topology. It aims at the characteristics of AANET. A new time division multiple access (TDMA) slot allocation method is proposed. Firstly, according to the characteristics of media access control (MAC) protocol in high dynamic aviation network environment. The calculation method of connection set which can share one time slot for communication is derived, and the optimal mathematical model of slot allocation for connection-oriented space multiplexing (TDMA / STDMA) is established. A distributed STDMA slot allocation algorithm, IDTA.IDTA, is proposed, which does not require central nodes to collect network information, and is divided into two synchronous processes running at both sending and receiving nodes. And the time slot can be allocated according to the priority of the connection. Finally, the computer simulation model is established on the OMNeT simulation platform. The simulation results show that the distributed STDMA slot allocation algorithm is more suitable for high dynamic aeronautical networks than other distributed STDMA slot allocation algorithms.
