    Interference on wireless sensor networks is a persistent challenge, especially when IEEE 802.15.4 operates in the 2.4 GHz frequency band which has already been crowded by various other wireless technologies, such as IEEE 802.11b/g (WLAN), IEEE 802.15.1 (Bluetooth), ZigBee and proprietary equipments. To maintain or even improve the wireless network performance, the estimation of wireless link quality is necessary. Our work in this thesis is prior to this estimation. We quantified both inter-and cross-protocol interferences by conducting various environments under different conditions. Our results not only offer valuable statistics about how IEEE 802.15.4 data communication can be impacted, but also provide fundamentals for implementing a WiFi interference model in simulators, for instance Cooja.
