Reinforcement Learning for P2P Searching
2005
For a peer-to-peer (P2P) system holding massive amount of data, an efficient and scalable search for resource sharing is a key determinant to its practical usage. Unstructured P2P networks avoid the limitations of centralized systems and the drawbacks of a highly structured approach, because they impose few constraints on topology and data placement, and they support highly versatile search mechanisms. However their search algorithms are usually based on simple flooding schemes, showing severe inefficiencies. In this paper, to address this major limitation, we propose and evaluate the adoption of a local adaptive routing protocol. The routing algorithm adopts a simple Reinforcement Learning…
Precio no monetario percibido en alojamientos e-peer-to-peer. La perspectiva de los huéspedes de Airbnb
2021
[EN] Price is considered as a key variable in predicting buying behavior. However, few studies have focused on how non-monetary price is affected and can affect other components of the consumer endogenous variables. This paper seeks (1) to analyze the effects of antecedents of behavioural price (past experience, the benefits and risks of peer to peer accommodation services) on the guest perceived price, and (2) to determine the effect of this price and past experience on guest intentions. With a sample of 136 Airbnb guests and the use of SEM, results show that past experience, financial risk, and time risk influence the non-monetary perceived price. This price and past experience affect gue…
The changing paradigm of document delivery : exploring researchers’ peer to peer practices
2016
Purpose By definition, interlibrary lending is a process involving two libraries. The digital revolution changed the method by which the scientific documents were disseminated during the past couple of decades. Nowadays, researchers can exploit several software applications that enable them to upload, save and deliver their documents from one peer to another without the need for a middle man. This paper reviews this change via a study conducted in two Finnish academic universities. The aim of this study was to determine the extent to which researchers have adopted these new possibilities for document dissemination and how this change will affect the role of the libraries in document delive…
How to Improve the Reliability of Chord?
2008
In this paper we focus on Chord P2P protocol and we study the process of unexpected departures of nodes from this system. Each of such departures may effect in losing any information and in classical versions of this protocol the probability of losing some information is proportional to the quantity of information put into this system. This effect can be partially solved by gathering in the protocol multiple copies (replicas) of information. The replication mechanism was proposed by many authors. We present a detailed analysis of one variant of blind replication and show that this solution only partially solves the problem. Next we propose two less obvious modifications of the Chord protoco…
