Resource-constrained maximum network throughput on space networks

This paper investigates the maximum network throughput for resource-constrained space networks based on the delay and disruption-tolerant networking (DTN) architecture. Specifically, this paper proposes a methodology for calculating the maximum network throughput of multiple transmission tasks under storage and delay constraints over a space network. A mixed-integer linear programming (MILP) is formulated to solve this problem. Simulations results show […]

Video Transmission Over Lossy Wireless Networks: A Cross-Layer Perspective

Video content currently makes up nearly half of the “fixed” Internet traffic and more than a third of the mobile traffic in North America, with most other regions showing similar trends. As mobile data rates continue to increase and more people rely on 802.11 wireless for home and commercial Internet access, the amount of video transmitted over at least […]

The Interplay Between Massive MIMO and Underlaid D2D Networking

In a device-to-device (D2D) underlaid cellular network, the uplink spectrum is reused by the D2D transmissions, causing mutual interference with the ongoing cellular transmissions. Massive MIMO is appealing in such a context as the base station’s (BS’s) large antenna array can nearly null the D2D-to-BS interference. The multi-user transmission in massive MIMO, however, may lead to increased […]

Software defined synergistic IP+optical resilient transport networks [Invited]

Integrated orchestration of the IP+optical transport network has been well studied in recent years and has become a realistic trend in telecommunication network deployments. OpenFlow-based softwaredefined network architecture is among the emerging and intensively investigated unified control plane solutions. Numerous previous works have focused on enabling optical networks to support the OpenFlow control plane, but mostly […]

Survivable virtual infrastructure mapping with dedicated protection in transport software-defined networks [Invited]

Efficiently mapping multiple virtual infrastructures (VIs) onto the same physical substrate with survivability is one of the fundamental challenges related to network virtualization in transport software-defined networks (T-SDNs). In this paper, we study the survivable VI mapping problem in T-SDNs with the objective of minimizing the VI request blocking probability. In particular, we address the subproblems […]

RAON: A recursive abstraction of SDN control-plane for large-scale production networks

In this invited paper, we introduce RAON: a recursive abstraction of SDN control-plane for large-scale production networks. RAON leverages a recursion, where the solution to a problem depends on solutions to smaller instances of the same problem, and organizes them in hierarchical domains. To this end, RAON abstracts the details of the underlying network as a […]

A Survey of Security Attacks in Information-Centric Networking

Information-centric networking (ICN) is a new communication paradigm that focuses on content retrieval from the network regardless of storage location or physical representation of this content. In ICN, securing the content itself is much more important than securing the infrastructure or the end-points. To achieve the security goals in this new paradigm, it is crucial to have a comprehensive […]

Human group sensing and networking: Scenario development and feasibility study

Vital signs obtained from people playing various types of sports can be exploited not only for diagnosing their physical conditions but also for learning the best practice to be followed to enhance their sporting abilities and skills. In this paper, focusing on a framework to collect vital data from a human group consisting of a […]

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 […]
