Abstract: Software-Defined Mobile Ad Hoc Network (SD-MANET) integrates the centralized control of Software-Defined Networking (SDN) with the dynamic networking capability of Mobile Ad Hoc Networks (MANET); however, existing simulation platforms like Mininet suffer from notable limitations in dynamic topology and scalability, which significantly hinder research on key SD-MANET algorithms. To address this, we propose NS3-SDMANET—an NS-3 based simulation platform—which implements simulations of SD-MANET network-layer features and offers programmable interfaces via Remote Procedure Call (RPC). Case studies in tactical networks demonstrate that NS3-SDMANET performs excellently in simulating critical network-layer characteristics, effectively enabling efficient validation and performance evaluation of SD-MANET algorithms, thereby providing a highly scalable and foundational simulation environment for further research.
