Problems solved by technology

However, most Ad-Hoc network protocol researchers focus on the research of complete and complex path discovery and routing algorithms, ignoring the fact that small-scale temporary communication networks have fewer routing hops (generally, two hops are sufficient for communication). demand) and other characteristics, applying these routing protocols to temporary mobile communication networks will surely achieve the desired effect, and complex routing algorithms will definitely bring higher protocol overhead and affect transmission delay

Embodiment Construction

[0040] The method will be further described below in conjunction with the accompanying drawings and embodiments, so as to facilitate the understanding of technical personnel.

[0041] In this method, first of all, a path discovery mechanism based on topology query is adopted. The entire network topology adopts a tree-shaped topology structure with this node as the root. Starting from the root node, the tree is traversed to obtain the For routing, when the topology is updated, it does not perform network-wide routing calculations, but only determines whether a path needs to be constructed through topology query, and constructs a path when a new node is added and sends an update message to other nodes.

[0042] Such as figure 1 Shown: the usable network topology node information storage structure of the present invention adopts a linked list structure to store network node information, and the meaning of each field is as follows:

[0043] MAC, indicating the MAC address of the ...

Abstract

The invention relates to a method for discovering and selecting a path of a mobile Ad-Hoc network and belongs to the technical field of network communication. The method for discovering and selecting the path of the mobile Ad-Hoc network, provided by the invention, maximally supports two-hop, can dynamically detect the change in network topology, can rapidly and accurately discover the path based on the topologically updated path discovery algorithm, and proposes a smallest load first (SLF) path selection algorithm as the optimum path selection criterion to reduce the algorithm complexity and thus to reduce the protocol overhead. The method is within the range of table-driven routing protocols, has a lower transmission delay, and is particularly suitable for small-scale temporary mobile communication networks.

Description

technical field [0001] The invention relates to a method for finding and selecting a mobile Ad-Hoc network path, belonging to the technical field of network communication. Background technique [0002] Since the emergence of Ad-Hoc networks, routing protocols have become a research hotspot in this field. So far, researchers have proposed many kinds of mobile Ad-Hoc network routing protocols. According to the triggering principle of the protocol, these protocols can be divided into three categories, namely a priori routing protocol, reactive routing protocol and hybrid routing protocol. The current research on Ad-Hoc network routing protocols is mainly based on the combination of theoretical research and experimental simulation. There are not many Ad-Hoc network routing protocols that can be practically applied, although some protocols have been applied in actual networks, such as AODV , DSDV and DSR and other typical protocols, but the performance of the protocol cannot mee...
