E-Mail Spam Filtering With Local SVM Classifiers

This paper describes an e-mail spam filter based on local SVM, namely on the SVM classifier trained only on a neighborhood of the message to be classified, and not on the whole training data available. Two problems are stated and solved. First, the selection of the right size of neighborhood...

TCP Over WiMAX Networks

The IEEE standard 802.16, also known as Worldwide Interoperability for Microwave Access WiMAX, is viewed as a powerful enabler for the massive deployment of high performance metropolitan area networks. It can also be viewed as one alternative to provide last mile access to Internet users, and therefore it is expected...

Dynamic Load Balancing in WDM Networks

This paper new load balancing techniques are proposed based on IP-like routing, where the forwarding mechanism is only driven by the destination address. The aim of this work is to consider the applicability of this approach in the context of optical networks. The proposed algorithm (RSNE - Reverse Subtree Neighborhood...

Programming Wireless Sensor Networks With Logical Neighborhoods: A Road Tunnel Use Case

Wireless Sensor Networks WSNs involving actuation are increasingly envisioned in a range of fields. Among these, there is considerable interest in leveraging off WSNs to improve safety in road tunnels. Researchers are envisioning tunnels equipped with WSN nodes that gather physical readings such as temperature and light, monitor the structural...

Highest Probability SVM Nearest Neighbor Classifier for Spam Filtering

This paper evaluates the performance of the highest probability SVM nearest neighbor classifier, which is a combination of the SVM and k-NN classifiers, on a corpus of email messages. To classify a sample the algorithm performs the following actions: for each k in a predefined set {k1, ..., kN} it...

TCP Westwood+ Enhancement in High-Speed Long-Distance Networks

In this paper, mechanisms to enhance the performance of TCP Westwood+ in the presence of a large Bandwidth-Delay Product are studied. In particular, the employment of a logarithmic function for congestion window increase in the absence of packet losses is proposed. Extensive numerical simulations, carried out by using ns-2, show...

Cross-Layer Adaptation of MPEG4 Video Streaming Over Wireless Networks Using Unequal Error Protection and MC-CDMA

A novel methodology for the efficient multiplexing and streaming of MPEG4 video over wireless networks is presented and discussed. The proposed cross-layer adaptation jointly exploits Variable-BitRate VBR Multi-Carrier Code-Division Multiplexing (MC-CDM) and MPEG4 Fine-Grain-Scalability FGS in order to provide unequal error protection to the transmitted video stream. A shared bandwidth...

The two hearts of LISA Pathfinder

As you might already know, LISA, a joint mission from ESA and NASA which is scheduled for 2014, will test the fundamental theories of gravitation, including Einsteins General Relativity. In "The day LISA Pathfinder hung in the balance," the European Space Agency reminds us that this mission relies on two...
