In this paper, we explore the physical-layer security in cooperative wireless networks with multiple relays where both amplify-and-forward (AF) and decode-and-forward (DF) protocols are considered. We propose the AF and DF based optimal relay selection (i.e., AFbORS and DFbORS) schemes to improve the wireless security against eavesdropping attack. For the purpose of comparison, we examine the traditional AFbORS and DFbORS schemes, denoted by T-AFbORS and T-DFbORS, respectively. We also investigate a so-called multiple relay combining (MRC) framework and present the traditional AF and DF based MRC schemes, called T-AFbMRC and T-DFbMRC, where multiple relays participate in forwarding the source signal to destination which then combines its received signals from the multiple relays. We derive closed-form intercept probability expressions of the proposed AFbORS and DFbORS (i.e., P-AFbORS and P-DFbORS) as well as the T-AFbORS, T-DFbORS, T-AFbMRC and T-DFbMRC schemes in the presence of eavesdropping attack. We further conduct an asymptotic intercept probability analysis to evaluate the diversity order performance of relay selection schemes and show that no matter which relaying protocol is considered (i.e., AF and DF), the traditional and proposed optimal relay selection approaches both achieve the diversity order M where M represents the number of relays. In addition, numerical results show that for both AF and DF protocols, the intercept probability performance of proposed optimal relay selection is strictly better than that of the traditional relay selection and multiple relay combining methods.

The challenging requirements of 5G, from both the applications and architecture perspectives, motivate the need to explore the feasibility of delivering services over new network architectures. As 5G proposes application-centric network slicing, which enables the use of new data planes realizable over a programmable compute, storage, and transport infrastructure, we consider information- centric networking as a candidate network architecture to realize 5G objectives. This can coexist with end-to-end IP services that are offered today. To this effect, we first propose a 5G-ICN architecture and compare its benefits (i.e., innovative services offered by leveraging ICN features) to current 3GPP-based mobile architectures. We then introduce a general application-driven framework that emphasizes the flexibility afforded by network functions virtualization and software defined networking over which 5G-ICN can be realized. We specifically focus on the issue of how mobility as a service (MaaS) can be realized as a 5G-ICN slice, and give an in-depth overview on resource provisioning and inter-dependencies and coordination among functional 5G-ICN slices to meet the MaaS objectives. The article tries to show the flexibility of delivering services over ICN where virtualization of control and data plane can be used by applications to meet complex service logic execution while creating value to its end users.

5G-ICN: Delivering ICN Services over 5G Using Network Slicing

Information-centric networking (ICN) proposes to redesign the Internet by replacing its host centric design with an information centric one, by establishing communication at the naming level, with the receiver side acting as the driving force behind content delivery. Such design promises great advantages for the delivery of content to and from mobile hosts. This, however, is at the expense of increased networking overhead, specifically in the case of Named-data Networking (NDN) due to use of flooding for path recovery. In this paper, we propose a mobility centric solution to address the overhead and scalability problems in NDN by introducing a novel forwarding architecture that leverages decentralized server-assisted routing over flooding based strategies. We present an in-depth study of the proposed architecture and provide demonstrative results on its throughput and overhead performance at different levels of mobility proving its scalability and effectiveness, when compared to the current NDN based forwarding strategies.

A Scalable Mobility-Centric Architecture for Named Data Networking.

Information centric networking (ICN) proposes to redesign the Internet by replacing its host-centric design with information-centric design. Communication among entities is established at the naming level, with the receiver side (referred to as the Consumer) acting as the driving force behind content delivery, by interacting with the network through Interest message transmissions. One of the proposed advantages for ICN is its support for mobility, by de-coupling applications from transport semantics. However, so far, little research has been conducted to understand the interaction between ICN and mobility of consuming and producing applications, in protocols purely based on information-centric principles, particularly in the case of NDN. In this paper, we present our findings on the mobility-based performance of Named Data Networking (NDN) in wireless access networks. Through simulations, we show that the current NDN architecture is not efficient in handling mobility and architectural enhancements needs to be done to fully support mobility of Consumers and Producers.

Mobility Study for Named Data Networking in Wireless Access Networks

A flow-driven forwarding strategy includes receiving an Interest packet, where the interest packet includes a flow state indicator. The content associated with the Interest packet is checked to determine whether that content is locally stored. Another check is performed to determine whether any previously received Interest packet has requested the content. In response to the content not being locally stored and no related Interest packet has been previously received, the flow state indicator is checked in the Interest packet. In response to the flow state indicator indicating that the Interest packet is associated with an active flow, forwarding information is extracted from a flow state table if a hop count has a value of zero or from the Interest packet if the hop count has a value greater than zero. The Interest packet is then forwarded to a next hop in accordance with the forwarding information.

Flow-driven forwarding architecture for information centric networks

The Internet of Things (IoT) promises to connect billions of objects
to the Internet. After deploying many stand-alone IoT systems in
different domains, the current trend is to develop a common, "thin
waist" of protocols to enable a horizontally unified IoT architecture.
The objective of such an architecture is to make resource objects
securely accessible to applications across organizations and domains.
Towards this goal, quite a few proposals have been made to build an
application-layer based unified IoT platform on top of today's
host-centric Internet. However, there is a fundamental mismatch
between the host-centric nature of today's Internet and the mostly
information-centric nature of the IoT domain. To address this
mismatch, the common set of protocols and network services offered by
an information-centric networking (ICN) architecture can be leveraged
to realize an ICN-based IoT (or ICN- IoT) architecture that can take
advantage of the salient features of ICN such as naming, security,
mobility, compute and efficient content and service delivery support
offered by it. In this draft, we summarize the general IoT demands,
and ICN features that support these requirements, and then discuss the
challenges to realize an ICN-based IoT framework. Beyond this, the
goal of this draft is not to offer any specific ICN-IoT architectural
proposal.

Design Considerations for Applying ICN to IoT

We present a novel approach to support stateless forwarding in information centric networks with emphasis on the CCN/NDN architectures by proposing a space-efficient in-packet filter based on the encoded counting bloom filter. Proposed solution avoids the typical pitfalls of using classic Bloom Filters by significantly reducing the false positive transmission attempts, while supporting reliable and resource efficient delivery of content packets to end hosts with minimal overhead. Comparisons to classic Bloom filter (and counting Bloom filter) based implementations suggest multiple times improvement in performance with the proposed solution without loss of support for stateless forwarding along the path.
