## 2 NDN-Based Wireless Mesh Networks
NDN-based Wireless Mesh Networks are also suitable for reducing the deficiency faced by wireless mesh networks regarding mobility. That deficiency relies on most routing protocols developed for IEEE 802.11 ad-hoc networks [19]. Therefore, physical mobility can significantly affect the performance of those wireless mesh networks protocols. This occurs due to constantly route changing between endpoints [20]. Thus, those protocols require a level of track state for at least part of the topology and route configuration when links change. The reason for this is that highly dynamic networks impose different issues to IP addresses regarding the assignment and reassignment to the constantly changing set of active nodes in the network [21]. Depending on the application, these address modifications also need to be mapped to tables with names and IP address. Compared with NDN, that problem would be reduced since the requests are no longer destination-oriented and thus, are content-oriented. Nowadays, mobile Internet traffic demand has increased the use of wireless networks, and the greater part of such traffic is content delivery, which is not real-time in nature [18; 22]. This traffic is suitable for caching and inherits the possibility of content sharing between consumers. The cache use provokes challenges on the ambit of how the storage resource will be managed. It has been reported that, for both wired and wireless networks, caching consists of two main problems: content placement and content delivery [18]. For content placement issues, like cache size, the cache location and discarding policy are essential structures of the problem. The content delivery problem is related to the efficient use of network resources to deliver content to their consumers. Also, some researchers are conducting experiments to fulfill the need for a lookup service to scale network routing. The work of [PERSON] et al. [23] proposed a new Domain Name System (DNS) protocol for NDN, called NDN DNS (NDNS). The authors designed a DNS service to provide a lookup named data service without the need to announce name prefixes into the global routing system. Another important aspect of NDN is the capability to use caches to promote popular contents. It has been reported that users send more than 300,000 tweets, share more than 680,000 pieces of content on Facebook, and upload 100 hours of video on YouTube per minute [24]. However few contents induce attention and concentrate most of the consumer requests [24]. [PERSON] et al. [18] stated that the fundamental feature of content delivery traffic nowadays is that a minority of popular contents represent the majority of the traffic load and are consumed by different users at different periods. Based on this behavior, it is important to predict if and when content will become popular. Nevertheless, there is a lack of ability to predict the popularity of web content. This shortage is provoked by a sum of aspects that impact directly on content popularity, for example, content quality and the importance of a content for consumers [25]. Those aspects are difficult to scope and may vary over time. [PERSON] et al. [24] argued that combining information from different media providers is the first step towards achieving better predictions. The authors also indicated that Twitter has been used for this accomplishment, but there are other promising content providers.
