Resumo
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.
