EcoRare: An Economic Incentive Scheme for Efficient Rare Data Accessibility in Mobile-P2PNetworks

摘要

We propose EcoRare, a novel economic incentive scheme for improving the availability of rare data in Mobile-P2P networks. EcoRare combats free-riding and effectively involves free-riders to improve the availability (and lifetimes) of rare data. EcoRare also facilitates the creation of multiple copies of rare items in the network since its novel selling mechanism allows a given data to have multiple owners. Our performance study demonstrates that EcoRare indeed improves query response times and availability of rare data items in Mobile-P2P networks.
