Filter bubbles and fake news

The results of the 2016 Brexit referendum in the U.K. and presidential election in the U.S. surprised pollsters and traditional media alike, and social media is now being blamed in part for creating echo chambers that encouraged the spread of fake news that influenced voters.

Clouds at the crossroads

Clouds at the crossroads

Despite its promise, most cloud computing innovations have been almost exclusively driven by a few industry leaders, such as Google, Amazon, Yahoo!, Microsoft, and IBM. The involvement of a wider research community, both in academia and industrial labs, has so far been patchy without a clear agenda. In our opinion, the limited participation stems from the prevalent view that clouds are mostly an engineering and business-oriented phenomenon based on stitching together existing technologies and tools.

A distributed security scheme for ad hoc networks

In an ad hoc wireless network where wired infrastructures are not feasible, energy and bandwidth conservation are the two key elements presenting challenges to researchers. Limited bandwidth makes a network easily congested by the control signals of the routing protocol. Routing schemes developed for wired networks seldom consider restrictions of this type. Instead, they assume that the network is mostly stable and that the overhead for routing messages is negligible. Considering these differences between wired and wireless network, it is necessary to develop a wireless routing protocol that limits congestion in the network [1, 5, 8, 9, 10, 11].This paper proposes minor modifications to the existing Ad hoc On Demand Vector (AODV) routing protocol (RFC 3561) in order to restrict congestion in networks during a particular type of Denial of Service (DoS) attack. In addition to this, it incurs absolutely no additional overhead [4]. We describe the DoS attack caused due to Route Request (RREQ) flooding and its implications on existing AODV-driven Mobile Ad hoc Networks (MANET) [2, 14]. To combat this DoS attack, a proactive scheme [12] is proposed. We present an illustration to describe the implications of RREQ flooding on pure AODV and the modified AODV protocols. To quantify the effectiveness of the proposed scheme, we simulated a DoS [6] attack in a mobile environment and study the performance results.
