Proper frequency planning is essential to enablemultiple IEEE 802.15.4 networks to coexist in the samespace, otherwise the network performance can beadversely affected due to interference. While this maybe feasible for static networks, it is not really an optionfor mobile networks such as body area networks due tothe dynamic nature of these interactions. This workdemonstrates one approach to detecting and mitigatinginterference in IEEE 802.15.4 networks from other802.15.4 networks. Interference is detected byobserving packets from other networks while themitigation strategy leverages collaboration betweeninterfering networks to determine which networkshould switch to a different channel. The approach canalso work with legacy networks that do not implementthis protocol. The system is implemented anddemonstrated on Intel Mote2 devices running TinyOS.
