Tetrapol is a digital professional mobile radio standard for digital voice and data communication used by public safety and military throughout Europe. Tetrapol was originally developed by Matra Communication (Currently part of EADS/Airbus Group) in France in the 1980's. At the time, the system was known as as Matracom 9600.
The first Tetrapol customers were the Gendarmerie (mid-1992) and the police (early 1995) in France. Today, Tetrapol technology is supported and is being further developed by two organisations: the Tetrapol Forum (predomi ....etc

Introduction

Software-Defined Radio (SDR) Forum defines SDR technology as radios that provide software control of a variety of modulation techniques, wide-band or narrow-band operation, communications security functions (such as hopping), and waveform requirements of current & evolving standards over a broad frequency range.

In a nutshell, Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio ....etc

MANET


1. Introduction
The term MANET (Mobile Ad hoc Network) refers to a multi hop packet-based wireless network composed of a set of mobile nodes that can communicate and move at the same time, without using any kind of fixed wired infrastructure. MANETs are actually self-organizing and adaptive networks that can be formed and deformed on the-fly without the need of any centralized administration. This exclusive characteristic allows the use of M ....etc

ppt for black hole attack in manet

Abstract

The black hole problem is one of the security attacks that occur in mobile ad hoc networks (MANETs). We present two possible solutions. The first is to find more than one route to the destination. The second is to exploit the packet sequence number included in any packet header. Computer simulation shows that compared to the original ad hoc on-demand distance vector (AODV) routing scheme, the second solution can verify 75% to 98% of the route to the destination depending on the pause times at a min ....etc

Security aspect in SDR and CR networks A survey and a way ahead



1) (T16)Jamming of the channel used to distribute cognitive information
.The cognitive control channel used to distribute cognitive information is jammed.
. It affects robustness ,system integrity, spectrum sensing and spectrum sharing .
.PT: is based on frequency hopping

2) (T17)Malicious alteration of cognitive messages.
.The cognitive messages exchanged in the CR network are altered.
. It affect ....etc
