Experimental Analysis of Concurrent Packet Transmissions in Wireless Sensor Networks [link]Paper  abstract   bibtex   
We undertake a systematic experimental study of the effects of concurrent packet transmissions in low-power wireless networks. Our measurements, conducted with Mica2 motes equipped with CC1000 radios, confirm that guaranteeing successful packet reception with high probability in the presence of concurrent transmissions requires that the \emphsignal-to-interference-plus-noise-ratio (SINR) exceed a critical threshold. However, we find a significant variation of about 6 dB in the threshold for groups of radios operating at different transmission powers. We find that it is harder to estimate the level of interference in the presence of multiple interferers. We also find that the measured SINR threshold generally increases with the number of interferers. Our study offers a better understanding of concurrent transmissions and suggests richer interference models and useful guidelines to improve the design and analysis of higher layer protocols.

We undertake a systematic experimental study of the effects of
concurrent packet transmissions in low-power wireless networks. Our
measurements, conducted with Mica2 motes equipped with CC1000 radios,
confirm that guaranteeing successful packet reception with high
probability in the presence of concurrent transmissions requires that
the \emph{signal-to-interference-plus-noise-ratio (SINR)} exceed a
critical threshold. However, we find a significant variation of about
6 dB in the threshold for groups of radios operating at different
transmission powers. We find that it is harder to estimate the level
of interference in the presence of multiple interferers. We also find
that the measured SINR threshold generally increases with the number
of interferers. Our study offers a better understanding of concurrent
transmissions and suggests richer interference models and useful
guidelines to improve the design and analysis of higher layer
