Abstract: The distinctive features make content-centric networking (CCN) as a potential networking scheme for mobile ad hoc networks (MANETs), such as asynchronous communication paradigm, in-network caching and multi-path forwarding, and thus, content-centric mobile ad hoc network (CCM) is becoming a hot issue in the area of CCN. Firstly, a content routing model of CCM is introduced, and then the major content routing schemes are elaborated. Furthermore, the existing issues are concluded in terms of broadcasting and routing model. The work shows the current research progress on content routing in CCM.
