Abstract: Underwater wireless communication system makes use of two communication modules which transmits and receives data using infrared radiation. Each module consists of both transmitter and receiver which transmits and convert received data. Wireless infrared (IR) communication system is meant to use free space propagation of light waves as a transmission medium in near infrared band This system has many advantages such as is an inexpensive and the transmitter or receiver can be showed to another location with least distraction.This system is used for easy communication with transmitter and receiver in underground water.The system consist of acknowledgement receipt message that sent back from receiving circuit to the transmitting circuit on the message receipt. This allows for efficient communication between two circuits wirelessly this paper puts forward an effective way of secured under water communication.
