Abstract


This article is dedicated Ad hoc network multicast technical error control study . With the development of wireless communication and computer network technology , the wireless network has been more and more attention in recent years due to its flexibility and practicality . Meanwhile, with the development of the multicast data transmission technology , how to wireless LAN technology and multicast applications combined and effective error control to provide reliable multicast transmission of information in the wireless LAN environment has also become the emerging research topics . Multicast and reliable multicast technology were analyzed , elaborated the concept of wireless local area network , which focuses on analysis of the Ad hoc network . Also discusses network routing protocols , of demand routing multicast definitions and related concepts . In Ad hoc network routing protocols on the basis of the analysis will be based on the Ad hoc network multicast routing protocol ODMRP ( On - Demand Multicast Routing Protocol ) as a key object of study , in ODMRP of foundation multicast fault-tolerant protocol design . By comparison , analysis and research , a new wireless ad hoc network multicast fault-tolerant protocol - ARMDP ( Ad hoc Reliable Multicast Data Distribution Protocol ) . The agreement by the use of efficient forward error correction ( FEC ) at the application layer and centralized automatic repeat request ( ARQ ) error control mechanism combination , effective control of the error , to ensure the efficient and reliable transmission of data . On the basis of the framework agreement , the article made ??a performance simulation. Simulation results show that : in the case of wireless Ad hoc network multicast applications , the proposed multicast fault-tolerant protocol to ensure reliable delivery of packets , and its end-to-end delay control in a relatively stable range , access to the preferably the multicast data transmission quality. ARMDP is a good error control , the smaller latency , stable performance suitable for wireless Ad hoc network multicast fault - tolerant protocol .
