Abstract

The invention discloses a network route selection method and system based on inter-node distance stability, and relates to the technical field of network route selection. According to the invention, GPS positioning information of routing equipment is mainly used to calculate the distance between the two nodes; the distance between two nodes is sampled for multiple times, a single-hop stable valuecalculation model between the nodes is constructed, a stable value between an intermediate node and a neighbor node of the intermediate node is calculated, the AODV routing protocol flow is redesigned, a route with the highest stability is selected, and effective transmission of data is realized. By applying the method and the system, the problems that the relative stability of the nodes is not considered in the path selection process of the traditional AODV routing protocol and link breakage is easy to occur are solved, and the waste of network resources is reduced.

Description

technical field [0001] The invention relates to the technical field of network route selection, in particular to a network route selection method and system based on stable distance between nodes. Background technique [0002] With the continuous advancement and development of science and technology, portable devices such as mobile phones, tablets, and laptops are gradually becoming popular, and a decentralized organizational network is born. MANET (Mobile Ad hoc network) network is also called mobile Ad hoc network. Ad hoc network is a kind of self-organizing network. The network does not need a specific network center and is formed automatically by nodes in the network. Due to the mobility and non-centrality of nodes, wired network routing protocols are no longer applicable. Typical protocols such as AODV, DSR, and DSDV, according to the different characteristics of these protocols, improved algorithms continue to emerge in order to improve routing performance.
