Cooperative ARQ with Fairness via Vickrey Auction-Based Spectrum Leasing

Cooperative automatic repeat request (ARQ) communication has been studied as a way to improve reliability of networks compared to conventional ARQ transmission scheme. We consider cooperative ARQ via Vickrey auction-based spectrum leasing, which is a communication scheme with a decentralized mechanism that motivates other non-cooperative nodes to participate as relay nodes in cooperative ARQ. Conventional researches of this model did not focus on fairness for amount of traffic flows among relay nodes' data. In this paper, we propose a new protocol considering this fairness by making autonomous-decentralized decision based on behavioral economic by each relay node evaluating own degree-of-satisfaction according to their acquired profits up to previous time auction. With computer simulation, we show that our proposal protocol has superiority to conventional schemes from the viewpoint of throughput and fairness index.
