Research:

Wireless and mobile computing are becoming mainstream at a rapid rate. Protocols to handle wireless communication are not mature given the wide array of demands placed on the spatial environment including connectivity, power usage, bandwidth, quality of service, and scalability. To address some of these issues, we are designing a simulation that will provide means to define the system type, topology, connectivity, environment, tasking equipment and operation specifications for a wireless local area network (WLAN).
The simulation will provide means to observe and report the system specifications and performance of the network system and subsystems. It will be partitioned into layers that accommodate varying levels of simulation fidelity. Examples include operations that use/measure performance characteristics, performance statistics, statistical models, heuristic models, physical models, and circuit level models. Equipment (i.e., access points, clients, interfaces, and interferes) will be implemented in the form of time domain state machines that are aware of a global temporal map. The temporal map will represent the equipment state, topology, connectivity, and environment. It will model synchronization of the network system and subsystems.
The simulation user interface will provide equipment specification in the form of type, modes, service, use, antenna, and other relevant operational characteristics. The connectivity of access points, clients, interferers, and interface signal sources will be mapped for both fixed and dynamic (protocol and/or motion driven) networks. The environment will be defined in terms of electromagnetic propagation characteristics, building use, type, and global noise sources. All simulation operations will be controlled using a real-time visual interface.
