Versatile Model Architecture for Multi-channel MAC Simulation in NS2

Research on multi-channel MAC has been got much attention in wireless networks. Extensions of NS2 mobile node architecture (MNA) to support multi-channel MAC simulation are not adaptable to home gateway configurations. This paper proposes a versatile model architecture (VMA) to make simulation of home gateway available. Based on the previous works, VMA defines an entity of data link adaptor and is capable to cover the configurations of multiple MACs and multiple multi-channel MACs. The paper presents how to extend MNA to VMA and how to modify NS2 simulation software. Validations of VMA-based multi-channel throughputs are present and discussed.
