Problems solved by technology

Therefore, in addition to the synchronization overhead between nodes, restricting the communication between nodes to a narrow communication window inevitably increases the collision probability and irrelevant data snooping
Therefore, using this traditional technology in a low-speed, node-intensive wireless sensor network cannot effectively alleviate wireless conflicts and save energy, especially in large-scale wireless sensor networks, this effect is more significant, which further increases the System Energy Consumption

Abstract

The invention discloses a wireless sensor self-organized networking method comprising: self-defining a wireless sensor network networking protocol, transmitting a network command layer upon layer by broadcasting, completing a function of communication path storage during the process of broadcasting, completing a networking function. Based on a clock synchronization technology, the method implements simultaneous dormancy and simultaneous wakeup of the whole wireless sensor network, thus reducing efficiently power consumption in the wireless sensor network.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a wireless sensor self-organizing network method. Background technique [0002] Wireless Sensor Network (WSN for short) refers to a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner. The monitoring information of perceived objects is widely used in information systems for monitoring and controlling objects and environments. [0003] Wireless sensor network is based on Micro-Electro-Mechanical System (English Micro-Electro-Mechanism System, referred to as MEMS), on-chip (English System on Chip, referred to as SOC), wireless communication and low-power embedded technology, and with its low power consumption, low The characteristics of cost, distribution and self-organization have brought about a revolution in information perception. The wireless sensor network is composed of a large number of cheap m...
