一种基于多接口多信道的移动Ad Hoc网络仿真平台实现方法

REALISATION OF MULTI-INTERFACE MULTI-CHANNEL BASED MOBILE AD HOC NETWORK SIMULATION PLATFORM

目前移动Ad Hoc网络的研究主要针对单接口单信道场景,但随着底层无线技术的进步和发展,一个节点往往可以具备多个接口,并且可以配置不同的信道。新的特性使得针对移动Ad Hoc网络的研究有了新的网络支撑环境。针对现有的NS-2环境下单接口单信道模型的不足,提出具有多接口多信道特性的移动Ad Hoc网络仿真平台的一种实现方法。实验结果验证了多接口多信道平台设计的正确性。该仿真平台的实现,使得多接口多信道环境下的移动Ad Hoc网络性能评估成为可能,并且能够方便对新研发协议进行测试。

Currently the study of mobile ad hoc networks （MANET） focuses on single interface single channel scenes. However, with the progress and developmerit of underlying wireless technology, one terminal can usually have multiple interfaces and can be configured with dif- ferent channels. This new feature makes the study on MANET with new network support environment. Aiming at the shortcomings of single in- terface single channel model in current NS-2, we present a implementation approach for mobile ad hoc networks simulation platform with the characteristic of multi-interface multi-channel. Experimental result verifies the correctness of the design of multi-interface multi-channel plat- form. The realisation of this simulation platform makes the performance assessment of MANET under multi-interface multi-channel environ- ment be possible, and can conveniently test the newly developed protocols.
