Economic Models for Data Management in Mobile P2P Computing

Speakers: Sanjay Kumar Madria
Topic(s): Databases & Information,Mobile Computing,Web Topics



Data Management in Mobile Peer to Peer (M-P2P) systems needs dynamic data management due to mobility and fragile wireless connection connecting resource constraint devices. Traditional methods of data management and services in mobile P2P environment generally assume all peers to cooperate. Since peer activities in M-P2P are not generally monitored, users assume that they are free to use the resources anyway they like.

Under this feeling of freedom, a subset of users (free riders) begins to
consume much more resources available on M-P2P than they wish to
contribute. In addition, due to the dynamic nature of moving hosts,
topology changes very often and traditional schemes fall short in
providing reasonable data availability. This becomes much more important in M-P2P where the network communication is generally multi-hop and intermediate peers have to render relay services other than data providers to improve the connectivity. Economic-based incentive schemesave been proposed which may play a better role in inciting free riderso collaborate. The data and service availability can be increased by
associating a price with data items and services. In such schemes, peers
can bid for better services, intermediate peers can earn incentives by
providing relay services and in fact, outgoing peers can lease data
items to others to still earn incentives while disconnected. New peers
can become data providers by providing hosting services to earn
incentives. This talk will provide schemes for managing resources using
Economic incentives.
