Problems solved by technology

[0003] Due to the invisible and non-intuitive nature of wireless sensor network data, current researchers mostly use simulation to test network protocols and programs. Although this method is convenient and feasible to a certain extent, it cannot fully reflect the wireless sensor network in the real environment. working status
As a result, there is a large error between the simulation results and the actual situation.
This is also a major obstacle in the current research on wireless sensor networks and related protocols.

Embodiment Construction

[0054] As shown in the figure, the present invention can use a wireless sensor node and a data acquisition module. The sensor node has the function of collecting and sending monitoring data, and is composed of Si4432 and ATmega32L microprocessors that meet the IEEE802.15.4 standard. The data processing chip of the data acquisition module adopts the CMOS microprocessor based on AVRRISC structure - ATmega128L chip and Si4432 wireless communication chip. The data acquisition module can be used as a Sink node to communicate with each node in the wireless sensor network wirelessly.

[0055] Such as figure 1 As shown, each module performs its own duties and does not interfere with each other, which reduces the coupling degree of the system and facilitates the modification and improvement of the software in the future. The "Model" part is the core of the entire software, it can directly access and process data, it encapsulates the data related to the business logic of the system an...

Abstract

The invention provides a wireless sensor network analysis method, belonging to the technical field of wireless sensor networks, relating to a wireless sensor network analysis method. The invention provides the wireless sensor network analysis method with good stability and visual display. The method comprises a model part of completing the data model of data processing, service logic, defining system processing of a system and comprises four types of frame formats comprising an IEEE 802.15.4 standard definition. The frame formats comprise a beacon frame, a data frame, an acknowledgment frame and a command frame, the command frame is divided into an association request, an association response, a disassociate notification, a data request, a PAN ID conflict notification, an isolated notification, a beacon request, and a coordinator rearrangement and GTS request.

Description
