Enabling ICN in IP networks via DNS Extensions: A Measurement Study

  • Hilt V.

ICN promises benefits to users and service providers along several dimensions, including lower response time, nearest-replica routing, intrinsic content integrity without external network-level indicators, location-independent naming and improved support for mobility. However, these benefits come at non-trivial cost as many ICN proposals call for adding significant complexity to the network. ...

Whether as telecommunications or power systems, networks are very important in everyday life. Maintaining these networks properly functional and connected, even under attacks or failures, is of special concern. This topic has been previously studied with a whole network robustness perspective. With this perspective, whenever a node is removed the ...

Opinion Manipulation in Social Networks

  • Silva A.

In this work, we are interested in finding the most efficient use of a budget to promote an opinion by paying agents within a group to supplant their true opinions. We model opinions as continuous scalars ranging from 0 to 1 with 1 representing extremely positive opinion. We focus on ...

Alternative Security Options in the 5G and IoT Era

  • Schinianakis D.

This article attempts to provide a set of new directions and ideas for research in the ever vibrant fields of telecom and IoT security. It attempts by no means to present a complete set of security solutions; this would be by definition impossible. It rather serves as a short but ...

The Imperative of Customer-Centric Operations

  • Cheikhrouhou A.
  • Davenport J.
  • Kelkar A.

Customer satisfaction drives better performance in the market and increased company value. Unfortunately, as is evident from lagging NPS scores, traditional service providers including MSOs have not performed as well as other industries despite allocating a proportionally much larger share of human resources in customer care. In contrast, web scale ...
