Embodiment Construction

[0022] In order to realize high real-time data broadcast distribution in the wireless ad hoc network, the technical scheme adopted by the present invention is as follows:

[0023] It is assumed that the nodes in the network obtain the complete topological connection relationship between each node in the network through topology learning. For the convenience of description, we use an undirected graph G=(V,E) to represent the topological connection relationship of the network, where V is the set of nodes in the network, and E is the set of connections between nodes in the network. For two nodes u and v with one-hop connection in the network, e(u, v) represents the connection between nodes u and v, e(u, v)∈E. Let N(u) represent the set of one-hop neighbor nodes of node u, N 2 (u) represents the two-hop neighbor node set of node u, and |A| represents the number of elements in the set A.

Abstract

The invention discloses a wireless self-organizing network high real-time data broadcast distribution method, comprising the following steps: Step 1, constructing a spanning tree: constructing a broadcast distribution tree with a source node as a root and nodes in a set R as branch nodes, Make the message data to be broadcast start from the source node, relay and forward along each branch node of the broadcast distribution tree, and then be transmitted to each node in the network; Step 2, planning transmission resources: relay forwarding sequence at the joint node On the basis of , allocate transmission resources for the nodes in the set R to maximize the multiplexing of transmission resources; Step 3, data broadcast distribution: notify the nodes in the set R and the transmission resources allocated to them to the corresponding nodes in the network, The received nodes forward accordingly according to the notification content. The invention effectively solves the problems of a large amount of redundant transmission and excessive distribution time delay in the traditional method in the multi-hop self-organizing network, and is a data broadcast distribution method with high real-time transmission.

Description

technical field [0001] The invention belongs to the technical field of wireless ad hoc network communication, and in particular relates to a method for realizing high real-time data broadcast distribution in a wireless ad hoc network. Background technique [0002] Broadcasting is a common communication requirement in wireless ad-hoc network communication, such as the announcement of important information, the issuance of instructions, and calling for user searches. The goal of broadcast communication is to transmit the message data sent by the source node to all other nodes in the network. Wireless ad-hoc network is a network that can be deployed quickly and flexibly. Its network topology may change continuously due to changes in node locations and communication environment, and the communication relationship between nodes is a multi-hop mesh connection. relation. In the wireless ad-hoc network, there is a big challenge in the problem of broadcast communication. How to mak...
