This paper is directed towards improving both throughput and reliability of 5G wireless Cloud Radio Access Networks (C-RANs) by the synergistic combination of Diversity Coding and Network Coding (DC-NC). In this paper, we directly apply the concept of DC-NC coding to two network scenarios: first, remote radio heads in a C-RAN connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links, second, most remote radio heads are connected directly to the baseband unit via wireless links. Our results show that the combination of Diversity and Network Coding increases the throughput of fronthaul networks for downlink broadcasting or multicasting applications, while enabling reliable networking with near-instant latency in fault recovery by using forward error control across spatially diverse paths. Moreover, the number of redundant links inherent in Diversity Coding can be decreased using the proposed scheme.

Reliable and resilient coordinated multi point fronthaul networks Sulieman, Nabeel I.; Balevi, Eren; Gitlin, Richard D. (2018-05-23) © 2018 IEEE.Very fast link failure recovery and high throughput can be achieved via the synergistic combination of Diversity and Network Coding (DC-NC), an open-loop coding technique, in a wide variety of network architectures. In this paper, DC-NC is applied to enable recovering from a wireless link/node failure in the fronthaul portion of downlink Coordinated Multi Point (CoMP) 5G wireless network in a C-RAN environment. Our results demonstrate that by utilizing DC-NC coding in CoMP systems, resource cons...
Near-instant link failure recovery in 5G wireless fog-based-fronthaul networks Sulieman, Nabeel I.; Balevi, Eren; Gitlin, Richard D. (2018-05-23) © 2018 IEEE.Rapid recovery from link failures was previously demonstrated via the synergistic combination of Diversity and Network Coding (DC-NC) for a wide variety of network architectures. In this paper, the DC-NC methodology is further enhanced to achieve near-instant recovery from multiple, simultaneous wireless link failures by modifying Triangular Network Coding (TNC) to create enhanced DC-NC (eDC-NC) that is applied to 5G wireless Fog computing based Radio Access Networks (F-RANs). In addition, an ex...
Information-centric sensor networks for cognitive IoT: an overview Al-Turjman, Fadi M. (2017-02-01) Information-centric sensor networks (ICSNs) are a paradigm of wireless sensor networks that focus on delivering information from the network based on user requirements, rather than serving as a point-to-point data communication network. Introducing learning in such networks can help to dynamically identify good data delivery paths by correlating past actions and results, make intelligent adaptations to improve the network lifetime, and also improve the quality of information delivered by the network to the ...
Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29) In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Routing and security in wireless sensor networks, an experimental evaluation of a proposed trust based routing protocol Chalabianloo, Niaz; İşler, Veysi; Department of Computer Engineering (2013) Satisfactory results obtained from sensor networks and the ongoing development in electronics and wireless communications have led to an impressive boost in the number of applications based on WSNs. Along with the growth in popularity of WSNs, previously implemented solutions need further improvements and new challenges arise which need to be solved. One of the main concerns regarding WSNs is the existence of security threats against their routing operations. Likelihood of security attacks in a structure su...
