ContikiRPL and TinyRPL: Happy Together

چکیده
IP-based sensor networks provide interoperability, but experience shows that interoperability between different protocol implementations is not a binary property. Instead, subtle differences in implementation choices may affect the performance of the resulting system. We present our experiences with the Contiki and TinyOS implementations of the IPv6 stack for low-power and lossy (LLN) networks including the IETF 6LoWPAN adaptation layer and the IETF RPL protocol. Our results show two independent implementations, that have good performance on their own, can have a substandard performance in a mixed network configuration and that small implementation differences can lead to large-scale differences in behavior. This suggests that IPv6 stack implementations for LLNs need to be tested not just for correctness but also for performance.

RPL Routing Protocol a case study: Precision agriculture
The routing protocol for low power and lossy network (RPL) was designed in the ROLL working group at IETF since the year of 2008. Until the latest version of draft 19 released, this protocol algorithms and its four application scenario, such as home automation, industrial control, urban environment and building automation, have been nearly grounded. However, it is still very difficult to find e...
متن کاملPoster Abstract: Low-Power Wireless IPv6 Routing with ContikiRPL
RPL is the IETF candidate standard for IPv6 routing in low-power wireless sensor networks. We present the first experimental results of RPL which we have obtained with our ContikiRPL implementation. Our results show that Tmote Sky motes running IPv6 with RPL routing have a battery lifetime of years, while delivering 0.6 packets per second to a sink node.

Responding to the increasing interest to connect wireless sensor networks (WSN) to the Internet, the IETF has proposed standards that enable IPv6-based sensor networks. Specifically, the IETF 6LoWPAN and RoLL working groups developed standards for encapsulating IPv6 datagrams in 802.15.4 frames, neighbor discovery, and routing that allow sensor networks to exchange IPv6 datagrams with Internet ...
