Software-defined networks (SDN) have quickly gained importance in telecommunications.This paper has examined the performance of SDN's techniques used in wireless networks, specifically in ad hoc mobile networks (MANET).The architecture of SDN control specially designed for MANETs has been proposed under the name RDSNET.RDSNET provides a solution to the design and deployment of the controllers in these networks.Several simulation scenarios were built in OMNET ++ to decide whether the design of a distributed or centralized controller was the most suitable for implementation.The results showed that the RDSNET distributed configuration yielded better performance.It was also shown that, despite the additional overload introduced by synchronizations, the performance was similar to a conventional MANET without SDN for the message success rate.However, the latency with RDSNET does not improve over SDN networks.Thus, though flexibility is the advantage of SDN for MANETS, latency is the main disadvantage.Keyword -Software defined
