This paper presents the recent results obtained from the work that have been carried out with the aim of implementing Source Routing Minimum Cost Forwarding (SRMCF) protocol over IPv6 and the TSCH mode of IEEE 802.15.4e (6TiSCH), evaluating the performance of these protocols for the Internet of Things (IoT) and for different applications in healthcare, medical monitoring and urban mobility. To perform the new experiments presented here, this work is making use of the OpenWSN project platform, which implements IEEE 802.15.4e in an open source environment. The evaluation process considers the most recent version of the OpenMote-B platform, by considering higher numbers of hop distances and different parameters, such as Packet Loss Ratio (PLR), throughput and Round Trip Time (RTT). Another goal of this work is to investigate the service quality of the IEEE 802.15.4e standard. The research efforts focus on the code programming, and the adaptation of the OpenWSN stack. Experimental results have shown that the proposed protocol is capable of reducing PLR and energy consumption in comparison to the Routing Protocol for Low Power and Lossy Networks (RPL). For a number hops lower than four hops, the RTT is shorter when the SRMCF protocol is applied.
