Example Embodiment

[0040] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0041] Memristor (Memristor) is a non-linear resistor with memory function proposed by Professor Leon Chua of the University of California at Berkeley in 1971 and confirmed by HP scientists in 2008. As the fourth basic element after resistors, capacitors and inductors, memristors are used to describe magnetic flux The relationship between and the charge q(t): M(q)=dφ(q) / dq, where: Obviously, the current i(t) flowing through the memristor and the voltage v(t) across the memristor satisfy the relationship: v(t)=M(q)i(t), it can be known that the memristor at a certain moment t 0 The memristive value M(q(t 0 )) is determined by the current passing through it from t=-∞ to t=t 0 The time integration of, thus showing the characteristics of time memory.

[0042] Taking into account the unique characteristics of the memristor, as well as its small size, low energy con...

Abstract

The invention discloses a wireless sensor network modeling method based on nonvolatile two-dimensional cellular automata. Particularly, on the basis of the spatial-temporal evolution rule of the two-dimensional cellular automata to a wireless sensor network, a large number of wireless sensor nodes in the wireless sensor network are regarded as cells in the cellular automata, fourth-class primary elements, namely memristors, with the memory function are introduced to construct the nonvolatile cellular automata, then, through the reasonably designed activation mechanism and the synergy between the cells, the states of center cells and the states of neighboring cells are synchronously updated while the neighboring states are asynchronously input, information interaction between the cells and the neighboring cells of the cells is greatly reduced, and energy consumption of cellular nodes is reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to the design of a wireless sensor network model. Background technique [0002] Wireless Sensor Networks (WSNs) are composed of a large number of miniature sensor nodes deployed in a certain area, and the nodes form a multi-hop self-organizing network system through wireless communication. Its purpose is to collaboratively perceive, collect and process the monitored objects in the network coverage area and send them to the observer. Due to its low power consumption, low cost, and self-organizing capabilities, it is widely used in environmental monitoring, biomedicine, emergency rescue, anti-terrorism and anti-terrorism, and remote control in dangerous areas. [0003] In practical applications, sensor nodes are usually deployed in harsh environments or inaccessible areas, and the intervals for human maintenance are long, which makes it impractical to frequ...
