To solve the redundancy of control overhead and coded packet transmission in data recovery phase of current network coding reliable multicast scheme in multi-hop wireless network,a high-efficiency reliable multicast routing algorithm based on network coding-HMNC was proposed. To control the network overhead and data average recovery delay,it makes use of the feedback information of upstream node in multicast tree instead of those sending by downstream node,adding a new caching mechanism. Simulation results show that HMNC improves the multicast performance in terms of average recovery latency and network control overhead compared with existing NCRM schemes.
