Routing method for mine hybrid wireless mesh network based on virtual potential energy field

Abstract

The present invention proposes a mine hybrid wireless mesh network routing protocol based on a virtual potential energy field. The protocol is based on the convergence characteristics of the mine hybrid WMN network data transmission, selects different network performance parameters to construct different potential energy fields, and sets the minimum value for the gateway node. Under the action of the potential energy field, the data packets converge to the gateway, and then routes are established according to the potential energy difference between adjacent nodes to provide differentiated services for different applications. The invention only needs local information to make routing decisions without acquiring the performance parameters of the entire network, and the distributed routing protocol has smaller network overhead and better scalability. Compared with the existing routing protocol, the present invention has more advantages in terms of end-to-end delay and delivery rate when transmitting two types of data. At the same time, the use of terminal nodes is balanced, which can prolong the network survival time and improve the network service quality.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mine hybrid wireless mesh network routing method based on a virtual potential energy field. Background technique [0002] At present, the wireless mesh network (WMN) routing protocols mainly include: destination node sequence distance vector routing protocol (DSDV), ad hoc on-demand distance vector routing protocol (AODV) and hybrid wireless mesh routing protocol (HWMP). in, [0003] Destination Sequential Distance Vector Routing Protocol (DSDV) is a table-driven prior routing protocol based on the classical Bellman-Ford algorithm. The self-organizing on-demand distance vector routing protocol (AODV) is built on the DSDV algorithm, but it only starts the route discovery process when needed, thus reducing the cost of route maintenance. Hybrid Wireless Mesh Routing Protocol (HWMP) is a hybrid routing protocol, which has the rapidity of a priori routing and the flexibility...
