HMNToolSuite: tool support for mobility management of mobile devices in heterogeneous mobile networks

This paper presents tool support for testing mobility of mobile devices in heterogeneous mobile networks. As mobile devices are growing and networks are becoming heterogeneous, their mobility management in heterogeneous mobile networks has become important. Nonetheless, previous network simulators have focused on handover protocols at layer 2 or layer 3, but have not focused on handover decisions at layer 7. This tool suite allows the user to create multiple types of mobile networks, mobile nodes, and network servers for testing mobility of mobile devices. Moreover, it also allows the user to create simulation scenarios and generates testing results based on users’ demands. This paper presents the requirements, design, and implementation of the tool suite. We show the feasibility of our tool using a case study of contextaware handover decision management.
