RID: radio interference detection in wireless sensor networks
— In wireless sensor networks, many protocols assume that if node A is able to interfere with node B’s packet reception, then node B is within node A’s communication range. It is also assumed that if node B is within node A’s communication range, then node A is able to interfere with node B’s packet reception from any transmitter. While these assumptions may be useful in protocol design, they are not valid, according to the real experiments we conducted in MICA2 platform. For a strong link that has a high packet delivery ratio, the interference range is observed smaller than the communication range, while for a weak link that has a low packet delivery ratio, the interference range is larger than the communication range. So using communication range information alone is not enough to design real collisionfree media access control protocols. This paper presents a radio interference detection protocol (RID) and its variation (RID-B) to detect run-time radio interference relation...
