This paper presents the development and the performance analysis of IEEE 802.15.4 Wireless Sensor Network (WSN) test bed for outdoor implementation. In particular, the analysis is focusing on the effect of environmental parameters including absorption, Line–Of–Sight (LOS) condition, humidity level and the presence noise frequencies to the link quality between nodes. The WSN platform is developed using an Arduino microcontroller board and SKXbee Pro module, a low cost Xbee series 1 IEEE 802.15.4 standards prototyping kit. Results indicate a substantial effect on Received Signal Strength Indicator (RSSI) values and packet loss indicator (PLI) in LOS condition and high noise environment. A proper procedure in outdoor WSN deployment planning is proposed and further studies can be done in various aspects such as using complex network topology and user interfacing.
