Abstract


Ad Hoc Networks networking flexibility, given its huge development prospects . However , Ad Hoc network link bandwidth is limited, unable to meet the growing communication needs . In recent years , many new technologies emerging , collaborative communication technology make full use of the radio waves all to the propagation characteristics of nodes in the network can be achieved through collaborative resource sharing , and thus improve the overall network performance . Paper first introduces the idea of ??the collaborative Ad Hoc Networks MAC layer design and features for multi-hop network , a collaborative media access control method ( CoopMAC - CTS) , the method through the use of high-speed node \node to complete the communication , and design reasonable handshake order to reduce the impact of the hidden terminal network . Simulation results show that CoopMAC - CTS is possible to improve the transmission rate of the network packet and can promptly silent more hidden terminal , to improve synergistic handshake success probability , thereby improving the number of retransmissions and throughput in the network . In addition, the article also CoopMAC-CTS and AODV 's end-to-end performance of the entire network ; Finally, in order to better use of collaborative communication technology to support multi-rate transmission , we propose an Ad Hoc network support multi- rate transmission cross-layer cooperative routing method to validate its superiority through simulation .
