Recently, there has been significant interest in the 6LoWPAN standard and its applicability to IoT. This project explores 6LoWPAN using unslotted CSMA-CA IEEE802.15.4 on a large testbed.

Two forwarding approaches described in RFC 6606 for 6LoWPAN routing are investigated on the testbed, namely “route-over” and “mesh-under”. Results are obtained for both low-noise and noisy channels. Our results show that, although performance is affected by multiple factors, including transmission power, network topology and channel noise, the use of route-over forwarding in general results in a more scalable and robust 6LoWPAN network than is obtained using the mesh-under approach.
