Abstract

The invention discloses a real-time multicast method in a wireless multi-hop network. The method comprises the following steps of: constructing a mesh network; assessing a network condition; adaptively selecting an optimum coding mechanism and coding parameters; performing coding operating by using a core node; processing by using an intermediate node; and processing by using a receiving node. The real-time multicast method in the wireless multi-hop network designed in the invention is applied to a real-time multicast service in a mobile ad hoc network, the optimum coding mechanism and the parameter can be adaptively selected according to the current network condition, the reliability and throughput of the network are improved, the overall energy consumption of the network is reduced and the requirement on the real-time property of services can be met.

Description

technical field

[0001] The invention relates to a real-time multicast method in a wireless multi-hop network, which improves the reliability and throughput of the network by combining forward error correction and network coding, while reducing the overall energy consumption of the network and meeting the real-time requirements of services . Background technique

[0002] The mobile ad hoc network has the characteristics of dynamic network topology changes, unstable transmission links, and limited node energy. How to implement real-time multicast in MANET has become a research hotspot in recent years. Generally speaking, a more effective multicast can be realized by constructing a multicast tree, such as MAODV. However, due to the relatively complex structure of the multicast tree and the large amount of network resources consumed by maintaining the multicast tree, the improvement of network performance is affected to a large extent, and even the network performance is reduc...
