Independent Submission J. Tripathi, Ed. Request for Comments: 6687 J. de Oliveira, Ed. Category: Informational Drexel University ISSN: 2070-1721 JP. Vasseur, Ed. Cisco Systems, Inc. October 2012 Performance Evaluation of the Routing Protocol for Low-Power and Lossy Networks (RPL) Abstract This document presents a performance evaluation of the Routing Protocol for Low-Power and Lossy Networks (RPL) for a small outdoor deployment of sensor nodes and for a large-scale smart meter network. Detailed simulations are carried out to produce several routing performance metrics using these real-life deployment scenarios. Please refer to the PDF version of this document, which includes several plots for the performance metrics not shown in the plain-text version.

Introduction Designing a routing protocol for Low-Power and Lossy Networks (LLNs) imposes great challenges, mainly due to low data rates, high probability of packet delivery failure, and strict energy constraints in the nodes. The IETF ROLL Working Group took on this task and specified the Routing Protocol for Low-Power and Lossy Networks (RPL) in [RFC6550]. RPL is designed to meet the core requirements specified in [RFC5826], [RFC5867], [RFC5673], and [RFC5548]. Tripathi, et al. Informational [Page 2] RFC 6687 Performance Evaluation of RPL October 2012 This document's contribution is to provide a performance evaluation of RPL with respect to several metrics of interest. This is accomplished using real data and topologies in a discrete event simulator developed to reproduce the protocol behavior. The following metrics are evaluated: o Path quality metrics, such as ETX path cost, ETX path stretch, ETXShow full document text
