Comparative Performance Study of RPL in Wireless Sensor Networks

In order to enable the interoperability of the IP-based WSNs with the Internet, the Internet Engineering Task Force (IETF) chartered the IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) and Routing Over Low power and Lossy networks (RoLL) working groups. The working group has been standardizing an IPv6 routing protocol for Low-power and Lossy Networks (RPL). This paper presents a comprehensive study of the performance of RPL when compared with Collection Tree Protocol (CTP). The aim of this work is to show the superiority of RPL in network scalability. Our results describe the benefit of RPL in terms of high Packet Reception Ratio (PRR) and low energy consumption. We also highlight the advantages in the design of the protocol, which can be used in further investigation of RPL.
