Auction based participant selection has been widely used for mobile crowd sensing (MCS) to achieve user incentive and assignment optimization. However, mobile crowd sensing problems solved with auction-based approaches usually involve participants' privacy concerns because a participant's bids may contain her private information (such as location visiting patterns), and disclosure participants' bids...
Research shows that location based routing can improve the performance and efficiency of communication in mobile ad hoc networks. From another point of view, disclosure of location information can cause a serious privacy risk, especially in environments where different groups of nodes cannot fully trust each other. In this paper, we propose a protocol through which a wireless node can achieve configurable...
Privacy preservation in a peer-to-peer (P2P) system tries to hide the association between the identity of a participant and the data that it is interested in. This paper proposes a trust-based privacy-preservation method for P2P data sharing. It adopts the trust relation between a peer and its collaborators (buddies). The buddy works as a proxy to send the request and acquire the data. This provides...
