Research And Implementation Of Access Strategy Of Multi-hop Wireless Network

With the development of telecommunication technologies, people much more relayon the board-band wireless access system. Because of the high speed of transmission,wide coverage and anti-fading competence, WiMAX is becoming a hotspot amongboard-band wireless access technologies. After the study of wireless access network, themulti-hop wireless network based on PMP topology network will be constructed, andthe dual-channel device will be designed.In order to enhance the performance of the multi-hop wireless network system andrelay transmission, access strategies are studied in this dissertation. The mainachievements are as follows:1. In order to carry out the basic functions for a multi-hop network system, thePMP topology network is used;2. In order to reduce the dependence on up-link communication conditions, amethod which is based on analysis is proposed. The method uses RNG-RSP message totransmit broadcast/multicast data;3. In order to increase the speed for frequency scan rate, aiming at the differentstages of system deployment, different channel frequency scan detection methods areprovided;4. Experiments are then carried out to verify these theoretical conclusions.
