Abstract

Wireless Ad Hoc Networks consist of devices that are wirelessly connected. Mobile Ad Hoc Networks (MANETs), Internet of Things (IoT), and Vehicular Ad Hoc Networks (VANETs) are the main domains of wireless ad hoc network. Internet is used in wireless ad hoc network. Internet is based on Transmission Control Protocol (TCP)/Internet Protocol (IP) network where clients and servers interact with each other with the help of IP in a pre-defined environment. Internet fetches data from a fixed location. Data redundancy, mobility, and location dependency are the main issues of the IP network paradigm. All these factors result in poor performance of wireless ad hoc networks. The main disadvantage of IP is that, it does not provide in-network caching. Therefore, there is a need to move towards a new network that overcomes these limitations. Named Data Network (NDN) is a network that overcomes these limitations. NDN is a project of Information-centric Network (ICN). NDN provides in-network caching which helps in fast response to user queries. Implementing NDN in wireless ad hoc network provides many benefits such as caching, mobility, scalability, security, and privacy. By considering the certainty, in this survey paper, we present a comprehensive survey on Caching Strategies in NDN-based Wireless Ad Hoc Network. Various caching mechanism-based results are also described. In the last, we also shed light on the challenges and future directions of this promising field to provide a clear understanding of what caching-related problems exist in NDN-based wireless ad hoc networks.
