“…In our study, DIRESC was compared against three well-known routing protocols, namely: CCN broadcasting [4], Probabilistic Interest Forwarding Protocol (PIFP) [39] and Social-Tie based Content Retrieval (STCR) [23]. Our rationale for choosing these protocols for our comparative performance study of DIRESC is as follows.…”

“…STCR and PIFP were selected as representatives of the class of social-assisted schemes that exploit the relationship between nodes to perform data forwarding in DTNs in our comparative analysis. PIFP presents better results for satisfied interest, average delay and total number of interest packets in dense scenarios, while STCR is better on the total number of data packets transmitted in the network [39]. DIRESC also follows in this category and was intended to overcome these limitations.…”

“…Inspired by Prophet [29], Duarte et. al [39] propose PIFP, a probabilistic interest forwarding protocol, which computes the probability of nodes coming into contact with the requested contents, so that the requests are transmitted only to high probability nodes. Content delivery is performed through the reverse path of sending requests, i.e., using Pending Interest Table (PIT) information as ''bread crumbs'' [4].…”

“…CCN has two types of messages, interest and data, which dictate the behavior of the network. In order to create messages of interest and data in the simulator, we generate two types of message, as defined by [39]: (i) interest messages, that holds the identifier for the source node, which is the node that originally generated the interest message (i.e., the requester), message size, and message name (i.e., prefix of searched content). During our simulations such messages are created at random nodes over the simulation time; and (ii) content messages, containing data uploaded by producer nodes.…”

“…We have validated and evaluated DIRESC performance in two scenarios: the former is a synthetic scenario Helsinki [39] using the Shortest Path Map-Based Movement mobility model in order to represent the pedestrians and cars nodes movements, and Map-Based Movement mobility model to represent the trains movement. The latter is San Francisco cabs [47] real mobility trace.…”

The paradigm of Content-Centric Networks (CCN) has been used in several networking application contexts in order to enhance the performance of data forwarding and retrieval. By disassociating device addressing from the packet routing process, CCN offers new message routing possibilities in network scenarios that are limited in this respect. An example of such scenarios concerns Delay/Disruption Tolerant Networks (DTNs), in which requesting and retrieving data and services may be even more unpredictable than simply sending any message from a source to a destination. With this in mind, we propose a DIscovery and REtrieval protocol based on Social Cooperation (DIRESC), designed specifically to perform data request and retrieval by applying the concept of CCN in the DTN scenario, an environment also known as Content-Centric Delay-Tolerant Networks (CCDTN). Our forwarding mechanism proposes the distributed sending of data based on the profile of each node, which is defined by its social interactions with other nodes. To evaluate our protocol, we used the Opportunistic Network Environment (ONE) simulator to compare DIRESC to other related CCDTN protocols, including our conceptual implementation of content-centric forwarding dubbed CCN broadcast. Results show that social cooperation has positive performance impact (i.e., improved delivery rate, delay, overhead, packet retransmission, and energy consumption) when compared to other social-oblivious CCDTN protocols.

Over the last couple of decades, vehicular ad hoc networks (VANETs) have been at the forefront of research, yet still are afflicted by high network fragmentation, due to their continuous node mobility and geographical dispersion. To address these concerns, a new paradigm was proposed -Information-Centric Networks(ICN), whose focus is the delivery of Content based on names, being ideal to attend to high latency environments. However, the main proposed solutions for content delivery in ICNs do not take into account the type of content nor the various available communication interfaces in each point of the network, a factor which can be deciding in mobile networks. The scope of this dissertation lies on the use of ICNs concepts for the delivery of both urgent and non-urgent information in urban mobile environments. In order to do so, a context-based forwarding strategy was proposed, with a very clear goal: to take advantage of both packet names and Data, and node's neighbourhood analysis in order to successfully deliver content into the network in the shortest period of time, and without worsening network congestion. The design, implementation and validation of the proposed strategy was performed using the ndnSIM platform simulator along with real mobility traces from communication infrastructure of the Porto city. The results show that the proposed context-based forwarding strategy for mobile ICN presents a clear improvement in performance in terms of delivery, while maintaining network overhead at a constant. Furthermore, by means of better pathing and through cooperation with caching mechanisms, lower transmission delays can be attained.
