Fault-tolerant recovery in Multicast communication is an important issue. An ideal multicast fault-tolerant approach can save network resources, reduce the delay and cost, realize quick recovery. In this paper, we propose a new multicast fault-tolerant approach-FH-TFTM based on proposed multicast fault-tolerant algorithms. It can go over problems faced in traditional approaches, for example node failure, unpredictable problems, time delay, network cost and loop avoidance. FH-TFTM can reduce consuming network resources, and carry out effectively setting up backup paths.

One of the primary difficulties in using powered parafoil(PPF) systems is the lack of effective trajectory tracking controllers since the trajectory tracking control is the essential operation for PPF to accomplish autonomous tasks. The characteristic model(CM) based all-coefficient adaptive control(ACAC) designed for PPF systems in horizontal and vertical trajectory control is proposed. The method is easy to use and convenient to adjust and test. Just a few parameters are adapted during the control process. In application, vertical and horizontal CMs are designed and ACAC controllers are constructed to control vertical altitude and horizontal trajectory of PPF based on the proposed CMs, respectively. Result analysis of different simulations shows that the applied ACAC control method is effective for trajectory tracking of the PPF systems and the approach guarantees the transient performance of the PPF systems with better disturbance rejection ability.
