Abstract
Recently, there has been significant interest in the 6LoWPAN standard and its applicability to IoT. This paper is concerned with 6LoWPAN using unslotted CSMA-CA IEEE802.15.4 and compares two forwarding approaches described in RFC 6606 for 6LoWPAN routing, namely "route-over" and "mesh-under". It extends previous work by evaluating both approaches on a large testbed. Results were obtained for both for low-noise and noisy channels. The results show that, although performance is affected by multiple factors, including transmission power, network topology and channel noise, the use of route-over forwarding generally results in a more scalable and robust 6LoWPAN network.Keywords
