Connecting NS-3 with Cooja

One research enabling factor of the Internet of Things (IoT) is the open array of network technologies that can be used to implements its systems. One of them is 802.15.4 that allows for an easy deployability due to their low cost, and mesh capabilities. However, due to their high latency, these networks should be restricted in size, hence the need to be combined with wider area technologies such as cellular networks. Such network can be simulated using ns-3. However, ns-3 does not simulate nodes running ready-to-deploy code. As opposed to Cooja, for instance, that simulates nodes running ContikiOS. In this paper, a framework is presented to connect ns-3 with Cooja in order to provide a tool to test 802.15.4 and their respective backbone networks with ready-to-deploy code.
