Ethernet-based avionic databus and time-space partition switch design

Avionic databuses fulfill a critical function in the connection and communication of aircraft components and functions such as flight-control, navigation, and monitoring. Ethernet-based avionic databuses have become the mainstream for large aircraft owning to their advantages of full-duplex communication with high bandwidth, low latency, low packet-loss, and low cost. As a new generation aviation network […]

A cluster based routing approach in LTE ad-hoc networks

In this work, a new routing algorithm which allows smart terminals to join the ad-hoc network at random times in order to carry out data transmission using Long Term Evolution (LTE) infra-structure has been developed and simulated by using OPNET Modeler. The routing scheme has been realized by clustering the terminals according to some predefined physical layer […]

Virtual network provisioning over distance-adaptive flexible-grid optical networks [Invited]

In software-defined optical networks (SDONs), network services are provided in terms of virtual optical networks (VONs). VON provisioning requires additional considerations regarding their optical characteristics and constraints compared to virtual networks offered in the electrical domain. In this paper, we present a new VON provisioning procedure that is specifically designed for distance-adaptive flexible-grid optical networks. […]

The Design of Safe Networked Supervisory Medical Systems Using Organ-Centric Hierarchical Control Architecture

There are growing demands to leverage network connectivity and interoperability of medical devices in order to improve patient safety and the effectiveness of medical services. However, if not properly designed, the integration of medical devices through networking could significantly increase the complexity of the system and make the system more vulnerable to potential errors, jeopardizing patient safety. The system […]

Digging the innate reliability of wireless networked systems

Network reliability of wireless networks exhibits a prominent impact in successful advancement of the networking paradigm. A complete understanding of the network reliability demands its in-depth analysis, which is yet to be attempted in the literature. Therefore, we present a comprehensive study on the network reliability in this paper. Our step-by-step stochastic study, from node-level to […]

Digital forensics in social networks and the cloud: Process, approaches, methods, tools, and challenges

As cloud computing and social networks become ubiquitous in our modern world, what come along with the nearly infinite storage and computing power are the security, privacy, and digital forensic challenges. Due to the completely different ways of data storage and processing in the cloud and social networks compared to their traditional counterparts, digital forensics practitioners are in need to […]

Social power for privacy protected opportunistic networks

Opportunistic networking poses a trade off. On the one hand, social links and the structure inherent in the opportunistic network are private information and should thus be protected. On the other hand, such information can be used to improve performance or security. We present an algorithm that can solve this dilemma: we can recognize pre-established […]

It also provides an overview of cloud computing, describing its key driving forces, characteristics and enabling technologies. The chapter focuses on the different characteristics of cloud computing systems and keyresearch challenges. It also compares cloud computing with other parallel and distributed computing models and highlights their […]

A study of user incentive mechanism in named data networking

Various named data networking (NDN) functions facilitate P2P content distribution, but the user incentive mechanism is missing. In this paper, we study the user incentive mechanism in NDN, particularly the information gathering, i.e., collecting user contribution information to be used to evaluate and reciprocate users, through simulations based on real Bit-Torrent trace. We found that two specific users […]

Design of energy efficient optical networks with software enabled integrated control plane

The growing energy consumption has posed new challenges for the future development of networks. Some earlier work has proposed solutions to improve energy consumption based on the existing control plane, for example, node/links sleeping. This study presents a new possibility to reduce network energy consumption by proposing a new integrated control plane structure utilising Software […]
