Abstract
In this paper, we propose effective schemes to stimulate cooperation between selfish nodes for data query and feedback in mobile opportunistic social networks. A query issuer generates a query and requests reply within a given delay budget. When a data provider receives the query for the first time from an intermediate node, the former replies it, and authorizes the latter as the owner of the reply. Multiple copies of a query can be created and replied by different data providers. When a node that owns a reply meets the query issuer that generates the query, it requests the query issuer to pay credits. The query issuer pays credits and provides a feedback of the reply to the data provider. When a node that carries a feedback meets the data provider, the data provider pays credits to the node in order to adjust its claimed expertise. Queries, replies and feedbacks can be traded between mobile nodes. We propose an effective mechanism to define rewards for queries, replies and feedbacks. We formulate the bargain process as a two-person cooperative game, whose solution is found by using the Nash Theorem. Extensive simulations have been carried out based on real-world traces to evaluate the proposed schemes.
