Uma Nova Política de Incentivos para Grades Computacionais Entre-Pares

Matheus GaudencioFrancisco Brasileiro

This paper presents a new resource sharing policy for P2P grids. Thisnew policy (NNoF) is based upon the Network-of-Favors (NoF). The NoF isa policy employed by the OurGrid Community to incentive resource donationusing a reciprocity strategy: the share of resources received by each node isproportional to the amount of resources donated by this node. However, the NoFisn't able to distinguish freeriders from nodes that consume more resources thandonates to a grid. The NNoF is able to provide a better reciprocity to donors,specially those with high consumption rate. This paper presents a evaluationthat shows the new policy capability of distinguish donors from freeriders.
