COOPERATIVE COMMUNICATIONS A NEW PARADIGM FOR WIRELESS NETWORKING? David Goodman Wireless Internet Center for Advanced Technology (WICAT) Polytechnic University

CHALLENGES OF WIRELESS NETWORKING zBandwidth zEnergy zMobility

CELLULAR PARADIGM zLICENSED RADIO SPECTRUM zFIXED NETWORK INFRASTRUCTURE zANYTIME, ANYWHERE zSYMMETRIC CHANNELS

WI-FI PARADIGM zUNLICENSED RADIO SPECTRUM zINFRASTRUCTURE or AD HOC zHOT SPOTS zASYMMETRIC CHANNELS

WI-FI vs. CELLULAR Isolated coverage Low mobility Interference Power Cost  Bit rate Power Cost Ubiquitous coverage Mobility Infrastructure WI-FI CELLULAR

WI-FI + CELLULAR zNOKIA: OWLAN zQUALCOMM: HOT-SPOT + CELLULAR BRIDGE zLUCENT: HAND-OFF (SEAMLESS CONNECTIONS) zCOOPERATIVE COMMUNICATIONS: INFRASTRUCTURE + AD HOC

NETWORK EFFICIENCY MSC

THEORETICAL INSIGHTS zIllinois: In dense ad hoc networks, throughput  constant (thpt/node  0) zU. C. Berkeley: In dense ad hoc networks with moving terminals thpt/node  constant (thpt  infty) zRutgers: Hot spots + mobility + P2P = fast, efficient dissemination

COOPERATIVE COMMUNICATIONS RESEARCH GOALS zEXPLOIT MOBILITY zEXPAND BANDWIDTH zEXTEND BATTERY LIFE zPROMOTE RELIABILITY, RESILIENCE
