Abstract
In this paper we proposed a model of transceiver section for wireless sensor node. This transceiver section uses optical signal for communication link. Currently communication in wireless sensor network is based on the radio frequency. Frequency 2.5GHz comes under the ISM band which is license free. But the use of same frequency creates interference problems in WSN. We also analyzed optical link for sufficient illumination and signal to noise ratio. New design of transceiver section of sensor node makes possible to route the data. Cost of sensor node will be low because of no regulation of frequency and use of white light emitting diode and photo detector pair.
