ONR Thrust Seamless, Robust Connectivity

• Multi-band / Multi-beam / Multi-function Wireless
  Signaling and Antennas
• Efficient modulation, coding, and antenna designs
  for high capacity communication links
• Adaptive Wireless Networking to support all users
  in a dynamic NCW radio relay grid
• Provide reconfigurable and robust networking
  within the grid between mobile, dispersed forces
  ashore and at sea
• Reliable and adaptive Quality of Service (QoS)
  and Bandwidth Management of user traffic
• End-to-end performance to the user (latency,
  bit error rate, precedence, etc.)

Seamless, Robust Connectivity

• Provide assured, user-transparent, rapidly
  adapted and reconfigurable communications
  connectivity between/among
• Globally dispersed sanctuary locations
• Ships, aircraft and submarines
• Positions in theater down to the lowest echelon
  Marine

High Capacity Communication Links

• Efficient Modulation and Coding Designs (more
  bps/Hz)
• Iterative decoding, Space-Time coding and MIMO
  channels
• Interference mitigation
• AWGN and LOS channels (jamming, interference,
  fading,)
• Low Probability of Interception/Detection links
• Low data rate voice
• Multi-band / Multi-beam / Multi-function Wireless
  Signaling and Antennas
• Ship SATCOM links
• Ship to aircraft links
• Integrate communications, surveillance and
  electronic warfare functions into a combined
  architectural concept
• Resource management
• Broadband (frequency) capability

5
Adaptive Wireless Networking

• Adaptive Wireless Networking to support all users
  in a dynamic NCW radio relay grid
• Mobile ad-hoc networking approaches (IETF MANET
  WG)
• Efficient channel access approaches
• Energy efficient wireless networking concepts
• Provide reconfigurable and robust networking
  within the grid between mobile, dispersed forces
  ashore and at sea
• UAV communications package (short/long ranges
  high/low alt.)
• UAV tactical phased array networking
• Joint/Coalition networking
• Joint Tactical Radio - Wideband Networked
  Waveform
• Next Generation IP Internetworking
• Migration from IPv4 to IPv6 over wireless
  networks

Quality of Service (QoS) and Bandwidth Management

• Reliable and adaptive QoS for all user traffic
  over heterogeneous networks
• End-to-end performance to the user (variable
  data rate, latency, bit error rate, precedence,
  etc.)
• Multi-layer QoS interactions and design
• Bandwidth and Resource Management
• Shipboard wireless communication links/networks
  in multiple frequency bands
• Management of shipboard communications,
  surveillance and EW resources
• Bandwidth management across multiple networks
  (BGP4 protocol extensions, border gateways,
  bandwidth broker concepts)

Summary - Focus Areas for Research

• Bandwidth Efficiency and Management
• Multi-beam, Multi-functional Antennas
• Adaptive, Self-healing, and Energy-Efficient
  Networking
• Sensor nets
• Mobile communications nets (terrestrial and
  airborne UAV)
• QoS across Navy, Marine Corps, Joint Forces and
  Coalition Forces
