An extension of NS-2 to support multiple networks

Network Simulator Version-2 (NS-2) is an open source simulation tool originally employed to explore the performance of a single network. However, recently many researchers expressed interest in issues related to Multiple Interfaces and Multiple Channels (MIMC), in particular how to efficiently utilize multiple channels. One such scenario is the combination of power line and wireless networking technologies in smart homes. According to the requirements of smart home networking for energy management, we established a simplified simulation model combining multiple networks. A single channel is assigned to each network to allow packets to be transmitted over various networks. The framework of our model could be further extended with existing or emerging network technologies to support more generic cases related to multiple networks.
