Content consumer mobility is an important aspect of content-centric networking (CCN) and future networks, but it has not been sufficiently studied. In this paper, we demonstrate that CCN can support faster communication services and provide uninterrupted data delivery in the 4G network and also in the upcoming 5G network. We propose an approach to integrate the CCN and LTE with high and seamless data delivery efficiency. We further propose a mobility management mechanism to support the network diversity by leveraging the abundant computation resources in the LTE network. To ensure seamless data delivery, we evaluate the performance of our proposed mechanism in terms of data transmission success ratio.

CCN is focused on the content itself rather than the host. CCN can be used to enhance the performance of delivery latency, robustness, and security. One of the immediate needs that CCN has to address is mobility support because the number of users who are using mobile devices is increasing rapidly. Users demand seamless handover when mobile devices move from one point of attachment to another point of attachment. In this paper, we first analyze existing approaches with respect to mobility, evaluate the performance of content-centric mobile networks in terms of handover delay and content delivery time, and show that content-centric networks work well in the mobile environment.

Because the traffic in the Internet and wireless network has been increasing rapidly due to the continued proliferation of mobile devices, it is important to minimize the content delivery time and avoid congestion in the network. Seamless mobility should also be provided to support service continuity when mobile users are moving from one domain to another domain in the wireless environment. In this paper, we present that CCN can support faster content delivery services as well as seamless services in wireless networks such as LTE. We also evaluate the performance of the content-centric LTE network via simulations.

With the expected connection among several tens of billions of addressable mobile devices and the exchange of a huge amount of content, the Internet and mobile communication are entering a new era that inevitably faces several challenges, especially from a content dissemination perspective. It has been exposed to many limitations such as high control overhead, frequent location updates, and network congestion. To resolve such limitations, this paper proposes an efficient hierarchical routing and content retrieval mechanism, which is called Hierarchical Routing (H-Routing) for the wireless network based on Content-Centric Networking (CCN). The H-Routing is composed of a novel content discovery approach and a common service platform for generic communications and the integration of heterogeneous devices. The proposed mechanism uses CCN and Chord-like lookup in a hierarchical M2M system in the wireless mobile environment. The H-Routing mechanism reduces unnecessary flooding of content request messages, control overhead, and the waste of resources. We also implemented the proposed mechanism in the simulation environment and analyze the performance in terms of throughput, Interest packet overhead, and Interest error ratio.

The existing paradigm of mobile multimedia sharing has yet to effectively address the energy and bandwidth limitations of wireless devices. Content-Centric Networking (CCN) has been proposed as a possible way to drive the current host-centric Internet paradigm towards a novel content-centric behavior. CCN still has some limitations in providing high-quality content, highly-reliable, faster, and efficient content sharing from multiple content sources, and no existing solution is available to retrieve contents over multiple paths. In this paper, we propose a content delivery and retrieval mechanism using multipath forwarding on top of CCN where contents are divided into multiple chunks and published from multiple mobile sources. It provides a new approach to allow multiple sources for content and to retrieve them chunk by chunk in parallel. We also present an implementation of our mechanism's basic operations and demonstrate the feasibility and performance of content retrieval from multiple content sources.

To overcome this limitation, there is a growing interest in the complementary network, e.g., challenged network, to provide direct communication among the mobile devices. Such networks may suffer from high delay, low data transmission rate, and frequent disconnections because of the mobility of the nodes and the time varying wireless channel condition that causes routes to fail frequently and thus content unavailability. In this paper, we propose a content popularity based data distribution mechanism that minimizes the content delivery delay and data storing cost, and also maximizes the network throughput. We also evaluate the performance of our proposed mechanism using simulation to show its feasibility and effectiveness.

These trends have motivated researchers to have interests in the future advanced mobile communications. In this paper, we concentrate on one of the most promising types of network, that is, mobile ad hoc network (MANET). Due to the highly dynamic network topology and resource shortage of MANET and the limited energy of communicating nodes, the communication route among nodes may fail frequently. To increase the applicability and sustainability of MANET in the future communication environment, we propose here a new routing protocol that constructs a stable, a reliable, and the shortest route having nodes with the minimum level of remaining energy to increase the operational lifetime of MANET. It also introduces a recovery scheme that reduces the network control overhead significantly to increase the reliability of the network. The effectiveness and robustness of our protocol and the corresponding data delivery mechanism make an ideal solution that can go a long way toward effective data dissemination in the future network.

Content-centric networking is greatly useful to increase the content availability and the efficiency of content delivery. Currently, the content-centric networking architecture is at an early stage, and it is not clearly defined yet in the wireless environment. In this paper, we propose a possible architecture, necessary components, and related mechanisms for multimedia content delivery in the wireless network. The proposed architecture is based on content-centric networking. We also present various simulation results to show that the proposed architecture and associated mechanisms work well in the wireless network.

The size of the Internet and the amount of the traffic are being expanded rapidly, which poses various challenges. In particular, the Internet and mobile communications are entering a new era that demands faster communication services and uninterrupted content delivery. A new paradigm called content-centric networking (CCN) is considered as an appropriate way for efficient content delivery. In this paper, we propose a CCN-based efficient content delivery mechanism in the 4G network and also in the upcoming 5G network where various heterogeneous networks are converged. We also propose a novel mobility management scheme to support the content diversity and network diversity by leveraging the abundant computational resources in the mobile network. In addition, we analyze the existing approaches with respect to mobility and evaluate the performance of our seamless content delivery mechanism in terms of content transfer time, throughput, and data transmission success ratio. Simulation results are also presented to show that the content-centric wireless network with our mobility management scheme can improve the data delivery services significantly compared to the existing schemes.

In this paper, we propose a link failure and congestion-aware reliable data delivery (LCRDD) mechanism that jointly exploits local packet buffering and multilevel congestion detection and control approaches for increasing the data delivery performance. On the detection of link failure or congestive state, an LCRDD intermediate node buffers the incoming data packets at the transport layer queue and resumes transmission when the route is repaired locally. In addition, LCRDD’s multilevel congestion detection helps it to take the most appropriate action proactively. Thus, it offers increased reliability and throughput and decreased end-to-end packet delivery delay and routing overhead compared to state-of-the-art protocols, as shown in results of performance evaluations carried out in network simulator v-2.34.
