Its system construction establishes the transmission path to carry on the intercommunication. However, the elementary routing protocol likes DSR and AODV have no mechanism to avoid network congestion. When the network loading becomes heavy, some real-time traffic will be convey un-success or be dropped because of the packet delay exceeds it’s delay upper bound. Therefore, the system efficiency will be decreased. We propose an admission control based on DSR. It not only contains bandwidth reservation to guarantee the transfer of flow, but also contains multi-path to improve the route maintenance. According to simulation results, we find system traffic effectively will be controlled. It also increases the transmission efficiency and decreases the delay of packet transfer.
