基于OMNeT++仿真平台的改进型USAP仿真分析

Improved USAP Simulation and Analysis Based on OMNeT++ Simulation Platform

飞行器Ad Hoc网络作为一种特殊的无线移动通信网络,被广泛应用于军事领域。统一资源指派协议USAP是一种适用于Ad Hoc网络的链路层协议,但在多节点网络中时隙分配效率低。本文在经典USAP的基础上,通过增加每一时帧中引导时隙的数量来提高节点间信息的交互效率,以提升多节点Ad Hoc网络的性能。利用OMNeT++软件对改进后的协议进行仿真,并和传统TDMA协议、经典USAP进行比较,比较可知改进后协议的性能得到了较大的改善。

As a special wireless mobile communication network,the aircraft Ad Hoc network is widely used in the military field.USAP,a unifying dynamic distributed multichannel TDMA slot assignment protocol, is a link layer protocol suitable for Ad Hoc networks.However,its slot allocation efficiency is low in a multi -node network.In order to improve efficiency,the number of bootstrap slots is increased in each time frame to enhance the interaction efficiency of information communication among nodes and the performance of multi -node Ad Hoc networks.Also,OMNeT ++software is used to simulate refined protocol which is compared with those of traditional TDMA protocol and classic USAP to demonstrate the superiority of this refined protocol.
