Description

technical field [0001] The invention relates to a calculation method for the transmission capacity of a wireless sensor network, in particular to a calculation method suitable for the lower limit of the transmission capacity of a mine roadway wireless sensor network. Background technique [0002] Wireless sensor network, also called Wireless Sensor Network (WSN for short), is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner, to cooperatively perceive, collect, process and The transmission network covers the information of the perceived objects in the geographical area, and finally sends this information to the owner of the network. Compared with the wired network, the wireless sensor network has the characteristics of strong self-healing, invulnerability, and large coverage area. It is very suitable for applications in harsh working conditions. Even if a major safety accident occurs, it will not be comple...

Problems solved by technology

However, since the wireless sensor network is a self-organizing network, the sensor nodes are randomly deployed in space, it is difficult to adopt centralized power control and access control methods, and each pair of relay nodes and sensor node links is very easy. Interferenced by other sensor node signals, coupled with the harsh environment of the mine roadway, the transmission signal is easily affected by fading, and, in general, it is difficult to obtain the analytical formula for the transmission capacity of the wireless sensor network, and it is also difficult to analyze the transmission capacity of the mine roadway. Optimized for wireless sensor networks

The above factors may cause communication interruption, reduce the transmission capacity of the wireless sensor network, and affect the safety production monitoring of coal mines.
