Social-Aware Stateless Routingin Pocket Switched Networks

Existing social-aware routing protocols for packet switched networks make use of the information about the social structure of the network deduced by state information of nodes (e.g., history of past encounters) to optimize routing. Although these approaches are shown to have superior performance to social-oblivious, stateless routing protocols (BinarySW, Epidemic), the improvement comes at the cost of […]

Software defined network traffic measurement: Current trends and challenges

Next generation networks such as Software Defined Networks (SDN) must support the integration of new paradigms of service offerings such as virtual cloud computing, big data applications, data centers services, and rich multimedia content. Operators of next generation SDNs are responsible for configuring policies that employ traffic monitoring tools and measurement mechanisms to detect and […]

Quality of service control and resource prioritization with Software Defined Networking

In this study, we aim to analyze how Software Defined Networking (SDN) can help to ensure a high-quality uninterrupted Voice over Internet Protocol (VoIP) service accompanied by video for prioritized users and entities in a network congested with background traffic. Guaranteeing a level of Quality of Service (QoS) and resource prioritization are key concepts for future networks […]

Elastic network functions: opportunities and challenges

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 […]

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 […]

APIs for QoS configuration in Software Defined Networks

The OpenFlow (OF) protocol is widely used in Software Defined Networking (SDN) to realize the communication between the controller and forwarding devices. OF allows great flexibility in managing traffic flows. However, OF alone is not enough to build more complex SDN services that require complete control and management of the data plane (e.g. configurations of ports, queues, etc.).The current […]

IASS: An intelligence access selection scheme for heterogeneous networks

In heterogeneous network environment, it is important to choose an appropriate access network for a Multimode Mobile Terminal (MMT). Currently, there are some methods proposed to make network access selection decision. However, those methods didn’t consider some dynamic attributes and could not offer effective handoff strategies. In this paper, we introduce an Intelligence Access Selection Scheme for Heterogeneous Networks […]

Seamless integration of Cloud and Fog networks

This work provides a way to merge Cloud Computing infrastructures with traditional or legacy network deployments, leveraging the best in both worlds and enabling a logically centralized control for it. A solution is proposed to extend existing Cloud Computing software stacks so they are able to manage networks outside the Cloud Computing infrastructure, by extending the internal, virtualized network […]

Analysis of Researcher Co-authorship Network

This work analyzes the co-authorship of science papers published by university teachers, and then constructs are searcher co-authorship network and characterizes the network by some varying quantities: the clustering coefficient, the average degree, diameter, average distance and components. Consequently, this paper visualizes the researcher co-authorship network which can lead to a better understanding of the applications of information visualization […]

Extending OpenFlow for SDN-enabled synchronous Ethernet networks

There is an increasing need of synchronization and clock frequency distribution in core and accessnetworks. Synchronous Ethernet (SyncE) is a technology that is able to distribute clock frequency over Ethernet networks, while keeping scalability and reduced costs. Software-Defined Networking (SDN) is another emerging technology that is changing the landscape of network management by separating the control and […]
