Mobile Ad-hoc NETworks (MANETs) enable users in physical proximity to each other to exchange data without the need for expensive communication infrastructures. Each user represents a node in the network, and executes a neighbor discovery protocol. Typically, nodes broadcast beacon messages that are received by other participants within the sender's communication range. Routing strategies are computed on-line based on the locations of nearby nodes, and geo-casting is employed to deliver data packets to their destinations. However, mobile users may be reluctant to share their exact locations with other participants, since location can disclose private details about a person's lifestyle, religious or political affiliations, etc.
