Autonomic computing and VANET

As modern wireless communication networks continue to spread in coverage and ubiquity, so do the applications for networks that take advantage of mobile technology. One of the more interesting areas of research and development is in the development and deployment of vehicular ad hoc networks (VANETs). VANETs offer the potential for intelligent transportation networks that […]

Extending OpenFlow for SDN-enabled synchronous Ethernet networks

There is an increasing need of synchronization and clock frequency distribution in core and access networks. 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 […]

Toward a semantic-based packet forwarding model for Openflow

Openflow is a step towards a more flexible data plane. In Openflow-based deployments, packet forwarding model relies on a set of pipelined tables. However, supporting multiple hardware tables is challenging while having serious limitations. In this paper, we investigate a novel approach to packet forwarding design that tailors Openflow forwarding paths according to the underlying […]

Analysis and Optimization of Random Sensing Order in Cognitive Radio Networks

Developing an efficient spectrum access policy enables cognitive radios to dramatically increase spectrum utilization while ensuring the predetermined quality of service levels for primary users (PUs). In this paper, the modeling, performance analysis, and optimization of a distributed secondary network with a random sensing order policy are studied. Specifically, secondary users (SUs) create a random […]

Strategic frequency adaptation for mid-range magnetic induction-based Wireless Underground Sensor Networks

Some classes of sensing applications target scenarios where the overall system, including antenna and energy sub-system, is placed under the ground, through concrete, or under-the-debris (disaster scenario). A real-time soil moisture sensing system deployed at the root zone of a crop area for precise irrigation and an oil pipeline leak detection (PLD) system are particular […]

Network economics in cognitive networks

Cellular networks are confronted with unprecedented pressure to accommodate the dramatically increasing demands of mobile Internet. This phenomenon is principally due to the restricted spectrum resource and low-efficiency spectrum management. Recently, cognitive radio technology has been corroborated to significantly improve spectrum utilization efficiency. In order to enhance the spectrum management efficiency in cellular networks, the […]

1.4 mA (70 mV) peak-to-peak drive of 1.25 Gb/s frequency modulated laser for WDM coherent access networks

A new laser suitable for access-systems with FM efficiency up to 7 GHz/mA and negligible amplitude modulation is presented. It enables 1.25/2.5 Gb/s operations with extremely low driving signals: 70 mVpk-pk and 250 mVpk-pk respectively.

This paper describes a method to support QoS using WebRTC-based Clients integrated in mobile devices conformed to 3GPP Rel. 8 Public Land Mobile Network infrastructure. To enrich the experience for mobile customers using this upcoming technology, the article focuses on the merging of the technical capabilities arising from both the Evolved Packet System inherent QoS […]

A Method for the Trajectory Privacy Protection Based on the Segmented Fake Trajectory under Road Networks

In recent years, LBS (Location-Based Service)have been widely used. According tithe historical location of user, location service providers may analyze the user’s interests, health and other personal privacy. The traditional k-anonymous protection method for trajectory mainly depends on the European space but not consider the road networks. In this paper, we proposed a method for […]

Incorporating Bacterial Properties for Plasmid Delivery in Nano Sensor Networks

The new paradigm of molecular communication aims to utilize biological components and systems for developing communication systems. One promising candidate for molecular communication is the use of bacteria to carry information between different nanomachines. However, there is a lack of connection between molecular communication and the design of nanomachines for payload delivery. Utilizing molecular communication […]
