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 […]
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 […]
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. […]
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 […]
As social networks are becoming more and more popular, more and more data are available from them. Researchers are now trying to extract useful information from these big data. One possible usage of social media is to investigate stock market. There are two major events to measure in stock market – price change and trade […]
Network function virtualization (NFV) and software defined networking (SDN) are key technology enablers for cost reductions and new business models in networking. The possibility to automatically and dynamically scale network services at run time is one of the main claims of NFV. Elastic NFV could be similar to what elastic cloud services provide for compute, with pay-per-use […]
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 […]
This chapter provides a general introduction to cloud networking, services, and management. 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 […]
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 […]
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 […]
