Since the early 1970s, ALOHA system in university of Hawaii appear, random multiple access technology achieved by leaps and bounds development, in the communication network, computer system, automatic control systems and other areas to be widely applied, promote the computer communication network, satellite communication, wireless self-organization communication network, the rapid development of wireless sensor network, etc. Also makes random multiple access control protocol theory constantly improve, formed the ALOHA multiple access technology, CSMA multiple access technology, CSMA/CD multiple access technology and CSMA/CA multiple access technology. At the same time, with the rapid increase of personal mobile communication technology and broad band wireless communication technology, and along with the going deep into research of random multi-access technology continuously, therefore according to different network conditions and higher requirements of application area, basing on the above mentioned two kinds of ones random multi-access protocols many novel protocols have being expend so that to complete the research of random multi-access protocols system continuously.With the rapid increase of multi-service of wireless communication network, more and more users got the rich and colorful and higher quality information services. However, the former more single QoS controlling tactics of service hasn't satisfied the higher QoS requirements of multi-service. Multi-channel and random multi-access protocols make the network possess many advantages such as reducing time delay, increasing throughput, using enough channels resource and meeting easily QoS. Therefore, use multi-channel random multi-access protocol to improve the frequency rate of utility, allocate corresponding resource in according to different QoS required by different kind of services and finally have far-reaching influence upon the development of mobile communication in the future. The research emphasis of the thesis is the wireless communication network.Papers from ALOHA multi-access technologies, CSMA multi-access technologies, CSMA/CD multiple access technology, CSMA/CA multi-access technologies and protocols expansion five described in section random multi-access agreement development process. And the random multi-access technologies and the combination of new technology are discussed, and analyses the multi-channel random multiple access technology in the application of the wireless network.Based on testing to torpedo the contents related wireless monitoring network, according to torpedo introduced wireless monitoring network testing puts forward four class CSMA/CA control protocols. Through the analysis of control protocol, and has established the effective mathematical analysis model, and gives out the lemma 1, proved theorem 1, theorem 2, theorem 3 and theorem 4. Then from the above lemma and four types control protocol theorem of proved, and gives the analysis first class control protocol analysis related lemma 2, proved theorems 5 and theorems 6. Given the second control protocol analysis related lemma 3, proved theorems 7 and theorem 8. Given the third class controls protocol analysis related lemma 4, proved theorem 9 and theorem 10. Gives the fourth control protocol analysis related lemma 5, proved theorems 11 and theorem 12. Through detailed theoretical analysis proof,4 kinds of control protocol throughput and related system properties is obtained. On the basis of theoretical analysis, the results of proof it numerical calculation and simulation experiment, gives up to 280 bar throughput analysis curves, and 280 largest throughput numerical. These analyses curve and numerical better reflects the characteristics of four types of control protocol. The theory analysis and numerical calculation and simulation experiment on the basis of summarized 5 of important conclusions. For further improving and optimizing the wireless monitoring network of torpedo testing ground, the CSMA/CA control protocol theoretic modeling analysis, and the development and application of application protocol has important scientific significance.
