Resource Acquisition by Explicit Remuneration for P2P-based Content Delivery
Joseph C. H. So · INTERNATIONAL JOURNAL OF NEXT-GENERATION COMPUTING · 2011
Many content delivery services are available in the Internet. Such service platforms are built on peer-to-peer (P2P) networks forming Internet clouds. P2P networks provide required resources to provide services with Service Level Agreements. In order to maintain the amount of resources, it is feasible for the service providers soliciting peers’ resources contributions by giving explicit remunerations. Naturally, service providers want to minimize the cost of remuneration, as long as the guaranteed services are fulfilled for all users. We consider a model defining the objective function to minimize this cost in service provision and propose a scheme of distributed and cost-efficient resource acquisition. This scheme incorporates the price elasticity of demand, the peer heterogeneity and the limitation of peer information. Our results show that, the SLA fulfillment, the cost efficiency and the load spreading can be enhanced by appropriate resource acquisition schemes even in a heavily loaded network.
