| Project Type |
Example |
| Adaptive Bandwidth Management |
New bandwidth management techniques are being developed to support growing levels of multimedia traffic, but the effectiveness of combined, related technologies is unknown. The objective is to develop an architecture to meet known QoS requirements. |
| Scalability of Wireless Network Communications Devices |
Existing and proposed mobile networking protocols have unknown scalability. Communication devices in production and development need to be tested for scalability. Existing and planned hardware devices are modeled in QualNet. Performance is analyzed across many different aspects of scalability, including number of nodes, density of nodes, percentage of sending nodes, node mobility, network traffic levels, and distance between source and destination nodes. |
| Validation of proposed design |
QualNet's simulation speeds are fast enough for the direct incorporation of source code from communication devices into QualNet. Validation of a proposed design also includes looking at scalability for small and large scale networks. |
| Representation of a network environment accurately, attributing for terrain, weather, signal interference, etc. |
QualNet offers large libraries of detailed network models including MANET, QoS, and wireless effects such as fading, signal to noise interference, pathloss, terrain, modulation, mobility and antenna models. Also supports detailed terrain models including CTDB, TIREM, DTED, and DEM. |
| Evaluation of tradeoff between performance goals and cost |
QualNet's high fidelity communication models and fast simulation speed allows for thorough investigation of parameters |
| Validation, design and testing of communication components. |
QualNet supports direct integration to real networks with IP Network Emulation, as well as to other simulations via HLA. |
| Parallel model optimization |
A customer is building a QualNet network model that runs on parallel processors. The model must achieve certain performance improvements relative to a previous sequential model. The model must also work on a number of different platforms (e.g., SGI, Sun, HP) with different hardware and software architectures. |
