The Internet of Things (IoT) is converging to multi-application scenarios demanding specific traffic standards and requirements. Such applications often rely on a single multi-hop wireless communication infrastructure, where smart devices collaborate to send collected data over an Low-Power and Lossy Networks (LLNs) through routing. RPL has emerged to use in scenarios where the devices are limited resources (processing, memory and power) in which is a routing solution for IoT LLNs scenarios. Although, there are some related work proposing the use of multiple instances in RPL on the same IoT network, those work have strong limitations to support multiple applications sharing the same network resources. We can cite, for instance, the lack of flexibility and dynamics in management of multiple instances and service differentiation for applications. In this context, the goal of this work is to develop a solution called DYNASTI, combining some mechanisms which provides dynamicity and flexibility by managing multiple instances of RPL. The benefit is the routing can further optimize network performance for the traffic from multiple applications with different requirements that are using the same wireless network infrastructure. In addition to support for sporadic applications and their coexistence with regular applications, DYNASTI achieved results that demonstrated a significant improvement in reducing the number of control messages, which resulted in increased packet received, decreased end-to-end delay, reduction in energy consumption and a slight improvement in service differentiation across the network.
