Abstract
Receive Signal Strength Indicator (RSSI) is one of performance metrics in wireless communications. The value indicates whether receiver could receive a packet. Since signal can reflex and refract from soil surface, underground nodes may not be able to communicate with aboveground nodes. One way solving this problem is to control the antenna orientation where antenna’s radiation pattern is in an appropriate direction.
