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.

1. 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].

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, ETX
