Review of routing protocols in wireless sensor networks

The trend of using wireless sensor networks has increased significantly in recent years due to their diverse use in various fields. A wireless sensor network is formed by connecting a large number of sensor nodes. Each sensor node deployed in the network monitors various parameters such as temperature, humidity, ambient light, gas, etc. and after collecting the required data, sends them to the main node. One of the important issues in wireless sensor networks (WSN) is the discussion of data transmission and the selection of the appropriate path for this transmission. The selection of an appropriate path depends on various factors such as accuracy in data transmission, energy consumption, delay, etc. Routing protocols are used to select the best path to transmit data from source to destination. The data collected in a wireless sensor network is sent by sensor nodes to the station. connects the sensor network to networks such as the Internet so that data can be viewed and analyzed. If the sensor networks are small and the sensor nodes are close to each other and can communicate directly with each other, these networks are called single-hop. But sometimes the area covered by the sensor network is so large that some nodes are far from the main node. Here multi-hop communication is necessary because the nodes cannot communicate directly with the base station. In this paper, the routing protocols of wireless sensor networks are analyzed.
