This paper presents a Tele-monitoring and management system for inter-cities transportation vehicles such as taxis and buses. The system is based on a stand-alone single-board embedded system that is equipped with GPS and GSM modems that is installed in the vehicle. A personal computer based GSM-Server is installed at transportation's head-quarter. While the vehicle is on the move, its real-time parameters such as speed, location, estimated arrival time, road condition and surrounding weather status are reported as SMS message to the transporta ....etc

It is a protocol that supports the delivery of POTS over the loop emulation service which helps to convey analog supervisory signaling states is commonly used by IWFs (interworking functions to support CCS ( Common Chanel Signalling). To avoid the signaling analog line states this protocol uses the simiar message set as the V5-PSTN (ETSI EN 300/324-1) thus covering the risk due to the variations seen in individual national implementation of analog POTS. ....etc

EMBEDDED SECURITY USING PUBLIC KEY CRYPTOGRAPHY IN MOBILE PHONES
ABSTRACT
As mobile networks expand their bandwidth, mobile phones, as with any other Internet device, become substantially exposed to Internet security vulnerabilities. Since mobile phones are becoming popular and widely distributed, they are increasingly used for financial transactions and related electronic commerce. Consequently, they will feature applications that also demand adequate security functions. In this regard, the prevailing security system in ....etc

Abstract”
The establishment of a Public Key Infrastructure (PKI) in Mobile Ad Hoc Networks (MANETs) is considered a difficult task because of the intrinsic characteristics of these networks. The absence of centralized services and the possible network partitions make traditional security solutions not straightforwardly applicable in MANETs. In this paper, we propose a publ ....etc
