Hello there,
Recently, I worked on a networking assignment where I had to compare the performance of a Software Defined Network (SDN) (designed using Mininet and Floodlight Controller) and conventional networks (designed using Packet Tracer). The task was to compare the ping and traceroute response of the SDN and a conventional network (which was designed to use BGP).
Though I'm not much familiar with the wireless sensor networks and Omnet++ (i.e. I can learn it, if it is required - not seems to be difficult at this moment), I would like take a look at the problem you want to solve and see if I can help you in the project.
Regards,
Atul Rajdhar
