Abstract - Internet Protocol is a long-lived, stable, and highly scalable communication technology. In order to extend application space of wireless sensor networks into Internet, technologies that can provide Internet connectivity to Wireless Sensor Networks have been developed and lead the concept of Internet of Things. However, most of operating systems that support IPv6 are based on the event-driven model. Although the multi-threaded operating systems have an advantage of developing higher-level applications and services more intuitively, there are no researches about implementing the IPv6 on top of them. In this paper, we implement the IPv6 network stack including RPL on top of NanoQplus. And we introduce a secure protection method that mitigates thread stack overflow, which may frequently occur with long computations such as handling IP packets in multi-threaded operating systems. As a result, the proposed method ensures that relatively long IP-related functions are executed safely. Our experiments on the real test-bed demonstrate that our RPL implementation also works correctly, and achieves above 91% delivery ratio using hop count as a routing metric.
