Forwarding Strategies in NDN based Wireless Networks: A Survey

Named Data Networking (NDN) is a promising Internet architecture paradigm of the future that adopts the Content Centric Networking (CCN) approach. Applications and users only care about the contents, while the Internet protocol (i.e., TCP/IP) focuses on communication by specifying and discovering the device location, which makes it more difficult and limiting. NDN supports the efficient distribution of the content, and secures the content rather than securing data channels. The forwarding mechanism in NDN-based wireless networks including MANET, WSN, VANET, and WMN are very important for efficient communication. NDN provides us a robust and simple communication mechanism. Two types of packets are exchanged over the networks in NDN forwarding: INTEREST and DATA. In this paper, a detailed survey is provided regarding forwarding strategies and forwarding issues in NDN/CCN based MANETs, VANETs, WSNs, and WMNs. Future challenges regarding forwarding in wireless environment are also highlighted.
