Embodiment Construction

[0031] 1. Architecture: The method of combining cellular automaton and agent to control the topology of wireless sensor network is mainly composed of two parts: one part is the whole cellular space model, and the other part is node agent.

[0032] 1. Cell space model of wireless sensor network

[0033] In a specific application, a wireless sensor network may consist of nodes with different structures, initial energy, and computing processing capabilities. This type of network is called a heterogeneous wireless sensor network. Even for a network composed of nodes of the same type, in order to prolong the life of the network, new sensor nodes are added on the basis of the original nodes, or because of link selection, each node cannot consume energy equally, so that the wireless sensor network It presents a characteristic of energy heterogeneity. In this way, the traditional cellular automata model cannot satisfy the wireless sensor network with multiple nodes. Therefore, some e...

Abstract

The invention discloses a self-adaptive topology control method for a wireless sensor network based on a cellular automaton and an intelligent agent. A multi-level cellular automaton method is adopted on overall modeling and the topology of the heterogeneous wireless sensor network is expressed by the change of a simple discrete state; the concept of the intelligent agent is introduced to abstract partial key nodes into the intelligent agents, so that the ability of the network for dealing with complex tasks independently is improved. According to the invention, relevant knowledge of complex systems and artificial intelligence and the wireless sensor network are combined together and a self-adaptive topology method is designed; and on the premise that the network coverage and the degree of communication are guaranteed, the energy consumption is saved and the service life of the network is prolonged.

Description

technical field [0001] The invention relates to an adaptive topology control method of a wireless sensor network, which mainly uses the combination of cellular automata and intelligent body technology to solve the network adaptive topology problem, and belongs to complexity science, theoretical biology, artificial intelligence and wireless sensor networks cross-technical application areas. Background technique [0002] Wireless sensor network is a special self-organizing network, the nodes of the network can sense, start, calculate and exchange information with other nodes through point-to-point multi-hop communication. Wireless sensor networks are used in a wide range of applications, including environmental monitoring, smart spaces, and medical systems. The goal of topology control is to find a node configuration method that can ensure the connectivity and coverage of the entire network topology on the premise of reducing system energy consumption. Using all nodes in the...
