SUMMARY To guarantee the QoS of multimedia applications in a mobile ad hoc network (MANET), a reliable packet transmitting mechanism in MANET is proposed. In this paper, we introduce an effective link lifetime estimation scheme. According to the current network topology and corresponding estimated link lifetime, the end‐to‐end connection is established adaptively in the best effort manner. Consequently, utilizing the network coding method the relay node combines and forwards the packets on the working path. Furthermore, to keep the balance between the gain in reliability and the amount of redundant packets, the time for sending the redundant packets on the backup path is determined for the link stability intelligently. Simulations show that our mechanisms can provide reliable transmissions for data packets and enhance the performance of the entire network, such as the packet delivery ratio, the end‐to‐end delay and the number of control messages.
