QoS Routing Protocol Research For UWB Ad Hoc Networks

UWB which is high-speed and low power consumption is the key technology oftransmitting data in short distance. In recent years, it has been widely researched anddeveloped, and has broad application and market prospects. Ad-Hoc QoS protocol basedon UWB is an important factor to the efficiency of UWB system. This study will realizethat the protocol that has QoS guarantee mechanism supports more than15network nodesof the network size, and supports multi-media services.This thesis has researched the UWB MAC protocol deeply and proposes a design ofUWB verification which is based on NDIS through the analysis of the actual features andapplication of ultra-wideband wireless communication system. This thesis analysis QoSmodel and routing protocol of MANET separately, and designs a QoS routing protocolwhich is suitable in UWB system based on the DS model and DSDV algorithm. Itoptimizes some parameters and strategies to meet the performance requirements of UWBsystem better.For the actual application, the thesis proposes test methods of system verification andtest environments, and gives the test results. The results show that it meets the targets ofperformance and QoS mechanism of the system will ensure the quality of point to pointdata service without significant delay, and distinguish different levels of data services. Inaddition, the thesis has conducted verification simulation of routing protocol throughOPNET software. The results show that that improved routing protocol achieves a higherefficiency with a lower cost, reduce the network load, meet the performance requirementsof UWB system and is applied in the actual system test with the link establishing in thecontrol of expect range.
