Using of multiple RPL instances for enhancing the performance of IoT-based systems.
2018
Modern technologies such as the Internet of Things (IoT) can be used to facilitate the provision of the services in different real-life applications. IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) is the routing protocol which was developed to act as an appropriate routing protocol in IoT-based networks such as Wireless Sensor Networks (WSNs). In RPL, a set of nodes which are having a common objective are grouped to represent what so-called: an instance. This paper provides a baseline to get benefits from supporting multiple RPL instances to be used for enhancing the performance of real-life systems. The performance is evaluated using Cooja simulator in term of two key routing performance metrics: average Packet Delivery Ratio (PDR) and average latency. The simulation results showed that by using the multiple RPL instances the performance is enhanced in term of the used performance metrics especially with the data traffic types which can be considered as critical data traffic.
