摘要: In wireless sensor networks, many protocols assume that if node A is able to interfere with B's packet reception, B within A's communication range. It also assumed range, reception from any transmitter. While these assumptions may be useful in protocol design, they are not valid, according the real experiments we conducted MICA2 platform. For a strong link has high delivery ratio, interference range observed smaller than while for weak low larger So using information alone enough design collision-free media access control protocols. This paper presents radio detection (RID) and its variation (RID-B) detect run-time relations among nodes. The results used TDMA With extensive simulations GlomoSim, network application scenarios, observe which uses 100% traditional loss up 60%, heavy load. addition scheduling-based protocols, explore of on contention-based MAC
