ADNP-CSMA Random Multiple Access protocol application with the function of monitoring in Ad Hoc network

In Ad Hoc networks, the net work of mobile nodes exchange information with their wireless transceiver equipment, the network throughput is in increased, compared to other such multiple hops network. Moreover along with the rapid development of modern information, communication business also will be increase. However, the access and adaptive of previous CSMA protocol are insufficient. According to these properties, this paper presents a kind of adaptive dual clock with monitoring function P-CSMA random multiple access protocol(ADNP-CSMA), and discusses two kinds of P-CSMA. ACK with monitoring function is introduced to maintain the stability of the whole system, and the introduction of dual clock mechanism reduces the channel of idle period. It calculate the system throughput expression through the method of average period, and the simulation results show that the system is constant in the case of high load throughput.
