2.5 Proposed Architectures for SDN in WSN
The novel idea of exploiting OpenFlow technology to address reliability issues in sensor networks was presented by (Arif Mahmud and Rahim Rahmani, 2011) at the IEEE International Conference on Computer Science and Network Technology while the first architectural proposal was presented by (Luo et al., 2012) in the form of Software Defined Wireless Sensor Network (SD-WSN). Up until now, very limited research work is carried out in this area. Some of the notable, proposed architectures for using SDN in WSN are:
• Software Defined Wireless Sensor Network (SD-WSN)
• TinySDN
• Service-centric networking for URban-scale Feedback Systems (SURF)
• Software Defined Networking in WIreless Sensor nEtworks (SDN-WISE)

This allows the VM to connect to the internet but in order to form a direct link between the VM and the host machine we need another Adapter Figure 15: Mininet-VM Network Settings

• Select Adapter and in the Attached to: field select the Host-only Adapter. The name for the adapter will automatically set to the newly created Host-only network. Click OK and start the VM. The username and password are both mininet

Step3: Configuring a new virtual interface
• This command will show the current available interfaces: mininet@mininet-vm:~$ ifconfig

Figure 17: Mininet-VM Terminal (ifconfig)

• To view all interfaces, even the ones that are down use the following command: mininet@mininet-vm:~$ ifconfig
