Abstract

The invention relates to a real-time wireless sensor network routing method supporting large-scale node application. A network is constructed by combining a core cluster head routing mechanism and a flat routing mechanism, so that routing is determined by frequency, and is independent of a specific node; a cooperative processing strategy and an energy balancing strategy are adopted between the nodes; the network is divided into grids according to the space density of the nodes, and an isolated point reduction optimization measure is adopted. According to the method, inter-network cluster-based routing signal interference is reduced, the problem of network disasters caused by routing node failures is solved, the reconstruction frequency of network clusters can be maximally reduced, the maintenance overhead of the clusters is reduced, and the response real-time performance of the whole network is improved.

Description

technical field [0001] The invention relates to the technical field of sensor networks, in particular to a real-time wireless sensor network routing method supporting large-scale node applications. Background technique [0002] In the process of realizing a large-scale wireless sensor network, it is necessary to face access to various types of sensors, and the energy consumption of various sensors is inconsistent. How to achieve energy saving and optimize the life cycle of the network in a large-scale network of mixed sensors It is an urgent problem to be solved in the sensor network; in a large-scale sensor network, how to provide the optimal routing, including the minimum energy consumption, the shortest path, the minimum number of hops, and the maximum and minimum remaining energy is also a problem that needs to be solved; how to ensure that the area coverage is satisfied Under the premise of the premise, saving system overhead, reducing the number of network isolated poi...
