One of the most promising frameworks to handle mobility management in wireless heterogeneous networks is the Media Independent Handover (MIH) standard. Among the services MIH is providing to achieve efficient mobility management, Information Services allow data exchanging between heterogeneous network nodes. In this paper, we propose an implementation of this Media Independent Information Services (MIIS) on Network Simulator 2 (NS2). With this implementation, new mobility and handoff scenarios can be realized. As an example, we study the case where a mobile node gathers relevant data of nearby networks through only one interface while keeping the others disconnected in order to save battery power. Results show that our implementation is fully functional and demonstrate how useful can be MIIS for mobility management.
