Recently, Content-Centric Networking (CCN) was introduced and is expected as a new concept of future internet architecture. Even though CCN is initially studied for wired networks, recently, it is also studied for wireless environment. In this paper, we discuss improvement method for efficient content flooding over wireless CCNs. The proposed scheme of this paper use MAC Address of nodes when Interest and Data Packet are forwarded in order to limit the area of flooding of packets. The proposed protocol not only reduces the spread of Data packets, but also offers priority of forwarding to nodes of shortest path. As a consequence, it reduce content download time which is proved by extensive simulations.
