Abstract


Multiple Access Control (MAC, Media Access Control) protocol is an important part of the Ad Hoc network , it has a direct impact on the performance of the entire network . In this paper, a MIMO technology based on the CSMA / CA protocol , the protocol using MIMO technology to achieve a parallel transmission links of the same or different types of interference , multi- node packet reception . This paper proposed MAC protocol also applies to the existence of a variety of link types ( multiplexed multiplexed link) and group network , and through simulation shows that the MAC protocol with good throughput and delay performance . Routing protocol is Ad Hoc important part of network design able to multi-input multiple-output ( MIMO Multiple Input Multiple Output ) technology fully used in the Ad Hoc network routing protocol is currently a hot research . Designed a cognitive routing protocol based on MIMO technology , through the use of MIMO technology , to the multi-antenna communication link has brought a lot of gain . These gain corresponds to a different type of link . In the agreement , it is reasonable to select a link type , Q-learning algorithm to achieve a cognitive process , learning and forecast the state of the network ; routing life and hello cycle based on the perceived status of the network settings , so that the performance of the network to reach optimal.
