PPP CHAP (Challenge Handshake Authentication Protocol) Modification for Wireless Internet Access of Remote Mobile Subscriber on GPRS (General Packet Radio Service) Network

Quality of Service Evaluation for Mobile Internet Access via the General Packet Radio Service ( GPRS )

Analysis of the General Packet Radio Service (GPRS) of GSM as Access to the Internet

The General Packet Radio Service (GPRS) of the Global System for Mobile Communications (GSM) is designed for packet switched data transmission and is a mean of mobile access to packet data networks, e.g. the Internet. Packet switched transmission is inherently better suited for bursty traffic as it is generated by typical Internet applications primarily WWW, FTP and e-mail. A simulator is prese...

Performance Simulation for the General Packet Radio Service, GPRS

Within the next year the first GPRS wireless packet data networks will be operable in Europe. In this paper, we study the capacity of the GPRS air interface under various conditions. For the analysis of the underlying Radio Link Control (RLC) protocol and the Medium Access Control (MAC) layer a simulative approach using OPNET is applied. Performance results for the RLC/MAC protocol are given fo...

Verification of two versions of the challenge handshake authentication protocol (chap)

The Challenge Handshake Authentication Protocol, CHAP, is an authentication protocol intended for use primarily by hosts and routers that connect to a network server via switched circuits or dial-up lines, but might be applied to dedicated links as well. In this paper, we specify two versions of the protocol, using the formal language LOTOS, and apply the EUCALYPTUS model-based verification too...

General Packet Radio Service (GPRS): architecture, interfaces, and deployment

This article provides an overview of General Packet Radio Service (GPRS). GPRS reuses the existing GSM infrastructure to provide end-to-end packet-switched services. Benefits of GPRS include efficient radio usage, fast set-up/access time and high bandwidth with multiple timeslots. GPRS also provides a smooth path for GSM evolution to the third generation mobile network. Specifically, a third ge...
