Cost-Aware Resource Acquisition for Guaranteed Service in P2P Networks

In order to provide guaranteed services in P2P networks, applications have to be supported by sufficient computing resources, especially bandwidths and storage spaces, which are acquired from the heterogeneous peers. As soliciting peers´ resources contribution by giving remunerations imposes an additional cost, the guaranteed services should be provided cost-effectively. In this paper, after defining the framework to analyze the cost implication, we propose a resource reservation algorithm called P2P User Requirement Acquisition scheme, PURE-A, which is distributed and cost-aware. In a network of the heterogeneous peers with limited local information, PURE-A is cost efficient in providing resource acquisition service to satisfy the QoS requirement.
