## 1 Introduction  
Wireless Mesh Networks (WMNs) are envisioned to be a solution to provide low-cost access to the Internet [1]. Basically, WMNs employ a wireless backbone composed of stationary nodes to increase the connectivity compared with ad hoc networks. Client nodes, mobile or not, access the Internet through one or more than one of these backbone nodes because they are usually configured as gateways. For this reason, nodes that are often in the shortest paths toward gateways forward more packets than the others do and thus, consume more than their resources [2]. In addition to the high concentration of traffic near gateways, WMNs also suffer from interference and collisions that are characteristic of wireless transmission. Nodes try to access the medium at each hop because WMNs are based on multihop communication. Therefore, packets that already traversed several hops can be discarded near their destination, which leads to resource waste [3]. The information-centric networking (ICN) paradigm is a solution for the problems cited above in WMNs [4; 5; 6; 7]. Information-Centric Wireless Mesh Networks focus on content delivery regardless of the content's physical location. Content requests and the contents themselves are forwarded based on names. Therefore, nodes have no addresses, and a content request is not necessarily addressed to a particular node with a well-known address. The ICN paradigm also assumes that all network nodes can cache contents [8]. Thus, any node can send the content in response to a request if the desired content is stored in its cache. Consequently, with ICN, a content request does not necessarily reach the gateway to retrieve the content from the Internet if another node has previously requested the same content. In this case, the traffic load in nodes near to the gateway decreases as well as the number of hops traversed by the content. Several architectures have been proposed in the literature to deploy the ICN paradigm both in the Internet and in wireless networks [9; 10]. Named-Data Networking (NDN) [11] is one of these architectures. NDN radically changes the TCP/IP paradigm and becomes more suitable for handling the challenges faced by new network applications. Currently, users of applications, such as BitTorrent and NetFlix, are more interested in the content itself than in who provides this content [12]. In 2017, 52.88 % of the Internet traffic was generated by Netflix, YouTube, and BitTorrent applications [13]. The way that consumers request contents in NDN improves the data delivery rate when compared with other destination-oriented network architectures [11]. NDN nodes request content by sending an interest packet that is forwarded through the network until it reaches a node that is able to send back a data packet with the desired content. This node can be the content producer or a node that stores the content in its cache because, with NDN, intermediate nodes can cache contents. This approach reduces the bottleneck on a content producers path. That is the reason why NDN improves the data delivery rate. NDN also has native mobility support because consumers request contents based on names and not based on the destination address as in IP networks. Also, nodes do not change their addresses during changes of access points [14]. Another feature of NDN is the reduction of the control message overhead on the network. This reduction occurs because nodes do not need to propagate routing tables and link changes to their neighbors. These features classify NDN as a promising network architecture for the future networks, including wireless mesh networks [15]. Particularly for wireless mesh networks, in-network caching reduces the traffic concentration near gateways and the waste of resources caused by the late drop of packets. NDN-based WMNs can also benefit from the broadcast nature of the wireless medium to disseminate interest packets. Hence, when a node sends a packet, more than one neighbor is able to listen this packet transmission.
