Abstract
The idea of multi-hop communication originates from the 1990’s and is eagerly incorporated in the wireless sensor network research field, since a tremendous amount of energy can be saved by letting —often battery powered– nodes in the network assist each other in forwarding packets. In such systems it is key-issue that the wireless medium is spatially reused. The lightweight mediumaccess control (LMAC) protocol relies for spatialmedium reuse on the following assumption [1]: a receiving node can distinguish
whether an erroneous packet is caused by an (concurrent)
interfering transmissions or due to e.g. noise.
In this paper this assumption is verified by path loss and interference measurements. Both outdoor (pasture land) and indoor (corridor) measurements were conducted.
From the results it can be concluded that there is a sharp defined communication range. And that packet errors within this range can be attributed to interferers that are within interference range.
