Host-based mobile ad hoc communication requires the transmission of periodic hello beacons to identify neighbors. Drawing conclusions from received beacons, e.g., containing information about existence and neighbor nodes, to available or demanded content is not possible and the gathered information may be outdated quickly due to dynamic environment changes. Therefore, content-centric networking results in more flexible communication without the need of neighbor information. Instead, information about available content is required. In this paper, the authors will investigate two different content discovery strategies and discuss their efficiency for mobile communication. The algorithms have been implemented in the CCNx framework and evaluated in VirtualMesh, a hybrid emulation tool for wireless mobile ad hoc networks.
