Abstract :
Network-to-network interference is a challenging problem in wireless body area networks which move frequently and operate in a non-coordinated way. In this paper, we characterize interference based on field measurements. We examine the correlation and independence between the desired (signal) and interference channels. The results show that over long periods, the two channels are statistically un-correlated. Over a short periods, the channels may become correlated, particularly when the channel variation is small.
