SOPRANO (Self-Organizing Packet Radio Ad hoc Networks with Overlay) involves a novel adaptive and scalable wireless network architecture utilizing a mixture of cellular and packet radio network topologies for wireless Internet and multimedia communications. The architecture enables rapid adaptability to traffic, channel and interference conditions and results in significant reductions in transmit power and potential throughput improvements. Coordination among physical, data link, and network layers enable significant improvements in capacity and quality of service relative to the current state-of-the-art.

  The main research thrust:

  o Capacity enhancement
  o Self-organization
  o Resource allocation
  o Adaptive routing
