With different applications and architectures, the wireless sensor networks have different communication protocols. This is the most typical protocol model used by sensor nodes. This model not only refers to the architecture of the TCP/IP and OSI models of the existing general network, but also includes the power management, mobility management, and task management platforms unique to the sensor network. The application layer provides a relatively uniform high-level interface for different applications; if necessary, the transport layer can maintain data flow or guarantee the connection with the Internet for the sensor network; the network layer is mainly responsible for data routing; and the data link layer coordinates the wireless medium. The visit minimizes the collisions when neighboring nodes broadcast; the physical layer provides a simple, stable modulation, transmission, and reception system for the system. In addition, the energy, mobility, and task management platforms are responsible for the monitoring of sensor node energy, movement, and task assignments, helping sensing nodes to coordinate sensing tasks and minimizing overall system power consumption. The wireless sensor network communication protocol uses five layers of protocols, namely, application layer, transport layer, network layer, data link layer, and physical layer, and corresponds to the five-layer protocol of the Ethernet protocol. In addition, the agreement should also include an energy management platform, a mobile management platform, and a task management platform. These management platforms enable the sensor nodes to work together in an efficient energy manner, forward data in sensor-mobile sensor networks, and support multitasking and resource sharing. The functions of the various layers of protocols and management platforms are as follows: 1. The physical layer provides simple but robust signal modulation and wireless transceiver technologies. The transmission medium can be wireless, infrared, or optical media. Wireless sensor networks mainly use wireless transmissions. 2. The data link layer is responsible for data framing, frame detection, media access, and error control. The data link layer ensures point-to-point and point-to-multipoint connections within the wireless sensor network. 3, the network layer is mainly responsible for route generation and routing. The sensor network nodes are distributed in or around the environment to be measured with high density. A special multi-hop wireless routing protocol is required between the sending node and the receiving node of the sensor network. 4. The transport layer is responsible for data stream transmission control and is an important part of guaranteeing the quality of communication services. The wireless sensor network has very limited computing resources and storage resources, and usually the amount of data transmission is not very large. 5. The application layer includes a series of application software based on monitoring tasks. 6. The energy management platform manages the energy use of sensor nodes—all of them need to consider energy savings in each protocol layer. 7. The mobile management platform detects and registers the movement of the sensor node and maintains the route to the sink node so that the sensor node can dynamically track the position of its neighbor. 8. The task management platform balances and schedules monitoring tasks within a given area.
