Research On Qos Mechanisms For High Dynamic Tactical Hyterogenous Networks

High dynamic tactical heterogeneous networks (HDTHN) is fused manycommunication means which including radio, microwave relay, lineate, fiber andsatellite. It provides seamless communications for command and control, situationapperceive, voice and other applications. HDTHN is an important component ofcampaign/tactical information system networks, and the main infrastructure of thefuture digital battlefield.Our subject investigated is the end-to-end QoS network of HDTHN. This thesis isresearch and discusses the architecture of HDTHN, end-to-end QoS network and someother content related based on labor comprehensive the basic feature and applicationrequirement.We contra poses features to HDTHN, and put a mixing end-to-end QoS modelwhich named H-EuQoS by analyze the adaptability of Qos model in existence toHDTHN, and presents a HDTHN to assurance the structure framework of terminal toterminal QoS based on H-EuQoS.We also develop a distributed bandwidth-constraint QoS routing protocol forHDTHN using heuristic distributed bandwidth-computing algorithm. Then the detaileddifferent routing strategies for various businesses HDTHN are given.Finally, we propose a general simulation framework for HDTHN using OPNET.This framework has the wholeness that includes different scheme designs and choices inthe physical layer, the link layer and the network layer. And a prototype of theframework is implemented in the case of comparing Qos routing protocol. Simulationresults further demonstrate that H-EuQoS mechanism is suitable for HDTHN.
