(PDAs, Notebooks, Phones, tablet PCs, etc) This article presents new approach, called Flying Emulator for testing mobile applications in different subnets within a LAN or WAN This article presents new approach, called Flying Emulator for testing mobile applications in different subnets within a LAN or WAN Key idea is to automate testing of applications designed for WLAN with subnets or LANs Key idea is to automate testing of applications designed for WLAN with subnets or LANs Why I chose this Article?

3. The Flying Emulator The key idea in this approach is to implement emulators as mobile agents that can travel from computer to computer under their own control. The key idea in this approach is to implement emulators as mobile agents that can travel from computer to computer under their own control. When an agent moves to another location, the agent transfers its state, as well as its code, to the destination. When an agent moves to another location, the agent transfers its state, as well as its code, to the destination. Carried software can continue its processing after arriving at the new host in the same way as it had been physically moved with target terminal. Carried software can continue its processing after arriving at the new host in the same way as it had been physically moved with target terminal.

5. The Flying Emulator This approach consists of three components: A mobile-agent-based emulator that provides the target software with internal execution environment, also carries the software to specific access point host on remote networks on behalf of the terminal. A mobile-agent-based emulator that provides the target software with internal execution environment, also carries the software to specific access point host on remote networks on behalf of the terminal. Access point hosts (APHs) that are allocated to each network and enable the software carried by the emulator to connect with various services.

Remote Control Server (RCS) – which enables remotely displaying emulator’s GUI on the screen. Remote Control Server (RCS) – which enables remotely displaying emulator’s GUI on the screen.

6. Mobile Termianl Emulation Each mobile agent based emulator can carry and test software designed to run on its target terminal. Each mobile agent based emulator can carry and test software designed to run on its target terminal. The current implementation of the approach is built on JAVA and provides mobile-agent-based emulators.

7. Emulation When emulator migrates between APHs, its target software is transformed into a bitstream along with states and codes then transformed to destination APH. When emulator migrates between APHs, its target software is transformed into a bitstream along with states and codes then transformed to destination APH. The Destination APH retrieves the software and emulator from the bitstream. The Destination APH retrieves the software and emulator from the bitstream. Developer can control the movement of the emulator interactively through the RCS. Developer can control the movement of the emulator interactively through the RCS.

10. Software Testing And RCS Developers use RCS to manage APHs, monitoring their status and controlling execution of the code.

11. Conclusion This approach enables application-level software to be executed and tested through its current network as if the software were being moved and executed on that target device. This approach enables application-level software to be executed and tested through its current network as if the software were being moved and executed on that target device. Approach still has issues and needs further testing and implementation. Approach still has issues and needs further testing and implementation.
