Abstract: In this paper channel prediction model of an outdoor environment using TelosB sensor nodes is develop. A Wireless Sensor Network (WSN) testbed comprising of four sensor nodes was built at the library field of Nnamdi Azikiwe University Awka. One of the sensor nodes is attached to the laptop which becomes the sink while the other 3 were placed at 00, 900 and 1800. RSSI measurement was taken at various distances up to 60m at the interval of 5m. The measured RSSI was used to develop the pathloss model of the environment using least mean square error method of linear regression analysis. The model developed was tested and the goodness of fit (R2) of the model was found to be 0.83. This shows that the pathloss model developed could be applied to an environment with similar radio characteristics.
