| Abstract: | Wireless Mesh network is an architectural multi-hop wireless network,and for its advantages of flexible architecture,rapid deployment,self-organization and self-healing,has broad and promising application prospects.The real-time data service in wireless Mesh network is modeled and simulated with ns-2 simulation software and IEEE 802.11 MAC and AODV routing protocol.The relationship between the transmission of data flow through the hops and throughput,the impacts of RTS/CTS,retransmission times in MAC layer and the interactions of MAC layer and routing layer on the performance of real-time data service are analyzed,and the potential approaches to enhanceing the performance of real-time data service in wireless Mesh network are discussed. |
