Abstract:  This talk addresses the issue of cooperation versus selfishness in wireless networks, and discusses possible performance gains, and implementation tradeoffs. The talk merges three different topics under the same umbrella: pricing for enforcing cooperation in slotted Aloha; adaptive channel allocation spectrum etiquette for cognitive radios; and interference aware routing for near-far effect mitigation. The common element is we show that in all three cases, cooperation can significantly increase the overall network performance.
