A reciprocation-based economy for multiple services in P2P grids
If you have a question about this talk, please contact Saar Drimer.
Designers of peer-to-peer grids aim to construct computational grids encompassing thousands of sites. To achieve this scale, the systems cannot rely on trust or off-line negotiations among participants. Moreover, without incentives for donation, there is a danger that free riding will prevail, leading the grid to collapse. Reciprocation-based incentive mechanisms have been proposed to deal with this problem. However, they have only been studied for the case in which a single service – processing power – is shared. In this paper we give a reciprocation-based mechanism for the case when multiple services, such as processing power and data transfers, are shared. In simulations of scenarios in which the services shared are combinations of two different basic services, the mechanism performs very well, even when the cost to peers of donating a service is nearly as large as the utility gained by receiving it.
