Embodiment Construction

[0030] In order to make the technical solutions and advantages of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all implementations. Exhaustive list of examples. And in the case of no conflict, the embodiments in this description and the features in the embodiments can be combined with each other.

[0031] The inventor noticed during the invention that:

[0032] Multicast in an Ad Hoc network is usually unreliable, and it is very difficult to implement reliable multicast, mainly because of the following reasons:

[0033] (1) Due to the limited communication range of nodes in the Ad Hoc network, multi-hop routing is often used to realize the long-distance communication process. However, as the number of routing hops increases, the communication proc...

Abstract

The present application provides a mobile ad hoc network and a multicast routing method thereof, comprising the steps of: each node in the network sends an MA message, and the MA message includes a stable value of each node itself; according to the The stable value of the node itself carried in the MA message sent by each node determines the core node; each node generates its own MA message according to the MA message of the core node to broadcast, and the broadcast MA message includes The distance from the node itself to the core node, the previous hop node information and the next hop node information; each node establishes a routing relationship according to the received MA messages broadcast by other nodes. Since the embodiment of the present application can determine the core node according to the stable value of each node itself, after the core node is determined, each node regenerates the MA message and establishes the routing relationship with each other after broadcasting, so that the constructed multicast group structure is more accurate It is stable and solves the problem of low reliability of multicast routing transmission in the prior art.

Description

technical field [0001] The present application relates to the technical field of mobile ad hoc networks, in particular to a mobile ad hoc network and a multicast routing method thereof. Background technique [0002] Mobile ad hoc network (Ad Hoc network) is a wireless network system without fixed communication facilities, which can be used in temporary network construction scenarios, and is widely used in military communication and disaster relief and other fields. During the multicast transmission process, the sending source only needs to send a data message, and the intermediate node uses the multicast protocol to build a multicast group (a set of receivers identified by an IP multicast address) transmission structure to copy and distribute the data message. Therefore, no matter how many destination addresses there are, there is only one copy of the datagram on any link in the network. [0003] At present, the multicast communication of data packets in the Ad Hoc network ...
