Embodiment Construction
[0029] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand the solution of the present invention more clearly, but the protection scope of the present invention is not limited thereby.
[0030] In the Ad-Hoc network described in the present invention, there are nodes, a source node, packets, channels. The present invention is mainly aimed at Ad-Hoc network single-hop situation, will held by source nodes It is a method to quickly expand a data packet to the whole network, which is suitable for all nodes in the network.
[0031] Nodes have two states, active and inactive. Active nodes send and receive messages throughout the network, while passive nodes just monitor whether to send and receive messages. In the initial state of the network, all source nodes are active, and other nodes are inactive.
[0032] network has a source node, this ...

The invention discloses an information exchange method based on a multi-channel Ad-Hoc wireless network. The method adopts the following technical scheme: nodes in the multi-channel Ad-Hoc wireless network are divided into two types, i.e., active nodes and inactive nodes; during each cycle, the active nodes update a multi-channel sending probability once and a main channel sending probability once; two sending processes, i.e., a multi-channel sending process and a main channel sending process, are employed during information exchange in the Ad-Hoc wireless network, and are executed in a parallel manner; each cycle is equally divided into four time slots, wherein the first two time slots are used for the multi-channel sending process, and the last two time slots are used for the main channel sending process; and each message sent by the active nodes can carry a plurality of data packets. The method provided by the invention has the advantages that the problems of an existing multi-channel Ad-Hoc wireless network that calculation of the number of network nodes is complicated because the nodes can move freely in the Ad-Hoc wireless network and that the optimum information exchange efficiency is difficult to achieve due to a single sending process are solved.
Description
technical field [0001] The invention belongs to the technical field of communication, in particular to a multi-channel-based Ad-Hoc network information exchange method. Background technique [0002] Ad-hoc wireless network is a multi-hop, centerless, self-organizing wireless network, also known as multi-hop network, infrastructure-free network or self-organizing network. The entire network has no fixed infrastructure, each node is mobile, and can dynamically maintain contact with other nodes in any way. The advantages of independence and invulnerability make Ad-Hoc networks widely used in real life. [0003] The independence of the Ad-Hoc wireless network is reflected in that compared with the conventional communication network, it can quickly build a mobile communication network at any time and any place without the support of hardware infrastructure network facilities, and its establishment does not depend on the existing Network communication facilities. This feature o...
