In order to solve the problem of the NCRM performance that is the network congestion occurring when the traffic loads sending too quickly in the mobile Ad hoc network. The article makes a mechanism of window-based TCP Vegas congestion control participate in NCRM to implement a window-based congestion control mechanism for multicast routing mechanism WCC-NCRM. The core idea in protocol is that the sending node comprehensive adjustment the sending speed of packets accord to the mechanism of send-window adjustment itself and feedback message triggering window adjustment,which also improve the defect of network congestion, thereby possibly reducing packet drop rate. The simulations reveal that the packet delivery ratio and total overhead of WCC-NCRM are superior to NCRM.
