Modeling and Simulation for Defence Communications
- NetSim supports the unique R&D requirements of the Defense organizations, Government agencies and Military that require detailed network modeling, and simulation that can keep pace with the growing size of tactical networks
- NetSim is used by the world's largest Defense organizations and contractors to accelerate the R&D of network protocols, devices, and architectures crucial to Network-Centric Operations and Warfare implementations
- Defense network planners and architects can analyze end-to-end behavior, tune network performance, and develop custom protocols to optimally support the warfighter. Training and exercise personnel can leverage NetSim to incorporate communications effects into war games.
Achieve a tactical advantage in the networked battlefield
- Use-cases can range from simple hand-held radios to vehicular radios, to airborne radios.
- Simulate battlefield communications involving voice, video and data transmissions over HF/UHF/VHF/L-Band/S-Band radios running various wireless waveforms
- Mobile Ad hoc Networks (MANETs) refer to a family of routing protocols developed to route traffic through mobile wireless networks. These networks place special requirements on routing protocols due the unpredictable nature of the radio links and changing network topology due to node mobility. NetSim can be used to simulate multi-hop bandwidth constrained Mobile Adhoc networks (MANETs)
- Connect your physical hardware to NetSim Emulator for system-in-the-loop simulations
- IP based MANET routing protocols DSR, AODV, OLSR and ZRP
- Bridge nodes to connect multiple MANETs, or to connect to backbone wired network
- Datalink Layer:
- Time division multiple access (TDMA) based on Link 16
- Dynamic TDMA (DTDMA): Allocation of the TDMA time slots to node is user defined, instead of being round robin.
- The configuration is done using the slot planner in the GUI.
- Ability for nodes to join and leave the network in run time
- PHY Layer:
- Frequency Range: HF, VHF, UHF, L-Band, S-Band
- Single channel. Narrowband or Wideband. User configurable Bandwidth
- Modulation Schemes: GMSK, BPSK, QPSK, 16-QAM and 64-QAM.
- Code Rates: 1/2. 2/3, 3/4, 5/6
- Frequency Hopping and Crypto.
- A wide range of RF propagation models covering pathloss, fading and shadowing.
- Mobility models:
