Papers of the Month: Detecting RF Devices & Embedded Multi-Core

The paper presents a series of techniques which goal is to detect the presence of RF signal from different devices such as bluetooth, Zigbee, etc. They main contributions is the use of commodity WiFi adapters which allows anyone to use the solution proposed.

The image below show an schematic view of the process of fingerprinting RF Signals and the pattern matching stage:

The detection rate is pretty awesome as shown in the next table:

This paper is pretty long paper by Freescale describing several features of MultiCore Systems from a developer point of view both Operating Systems and application programmers. It covers basic techniques when dealing with MultiCore systems but provides some good aspects to state-of-the-art on this area and where the industry is heading.

It also describes how virtual platforms allow developers to make better use of these kind of systems for example running a dedicated RTOS in a core a having a general purpose OS in another.

It is a good reading to brush up some concepts and get a better picture since MultiCore System will become the standard in the near future.
