Wireless Sensor Network Node Deployment Method for Soil Salinization Monitoring

Soil salinization is one form of soil degradation. In this paper, the formation of physical topology known as node deployment in wireless sensor networks is studied based on the characteristics of wireless sensor networks. After calculating the value of the edge length of the grid, the minimum number nodes achieved according to the relationship between the radius of node sensing and radius of node communication. For data transmission, a mobile sink energy efficient routing algorithm based on the shortest path was applied to reduce the energy consumption.
