| Abstract: | Along w it h the deep analysis of the topology structure and communication protocol of the wireless network,the limitation of the basic asynchronous data transfer method based on DCF is summarized at first.And then the RTS/CTS transmission mechanis m which is used to solve the limitation of the basic transfer method is carefull y studied.At the same time ,relevant problems are also discussed such as c ollision avoidance,hidden terminal and virtual carrier sense.At last,an exam ple of a new DIS prototype structure based on the connection of wired and wirele ss network is put forward by this paper. |
