EcoBroker: An Economic Incentive-Based Brokerage Model for Efficiently Handling Multiple-Item Queries to Improve Data Availability via Replication in Mobile-P2P Networks

摘要

This work proposes EcoBroker, a novel economic incentive-based brokerage model for improving data availability via replication for multiple-item queries in Mobile-P2P networks. In Ecobroker, data requestors need to pay the price (in virtual currency) of their requested data items to data-providers. The main contributions of EcoBroker are two-fold. First, its economic incentive model effectively combats free-riding by incentivizing MPs to become brokers and to host replicated data, thereby improving data availability. Second, its brokerage model facilitates efficient processing of queries involving multiple data items. Our performance evaluation indicates that EcoBroker indeed improves data availability and querying-related communication overhead in Mobile-P2P networks.
