Extending DCE to emulate Wireless Software Defined Networks.

Participants: Emilio Mancini, Hardik Soni, Thierry Turletti and Walid Dabbous.

Today it is not possible to simulate and evaluate in a realistic way wireless Software Defined Networking solutions. Indeed, the most used SDN emulator tool, Mininet, can only emulate point-to-point physical links using virtual Ethernet pairs (e.g., MAC layer is ignored), and it cannot provide mobility models for wireless nodes. To make the Direct Code Execution module (DCE) able to run Software Defined Networks we started to support OpenFlow NOX controller and Open vSwitch. The actual NOX binary is executed on a simulated ns-3 node. OpenFlow wireless routers are simulated using the Open vSwitch distribution with data-path kernel module support as it is widely used. DCE provides a mechanism to incorporate such a kernel module based application execution. A demonstration has been done at the 17th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems [29] .
