ABSTRACT
The aim of this paper is to understand the architecture of the GPRS and focus primarily on the issue come up while migrating from existing GSM network to that of GPRS.The migration path from GSM to GPRS requires additional packet switching nodes, software upgrades in the base station subsystem. The existing GSM nodes to upgrade with GPRS functionally, command data service to provide for this GPRS operation need to deploy other elements access serves and firewalls
The general packet radio system is a new non-voice ....etc

Definition

The General Packet Radio System (GPRS) is a new service that provides actual packet radio access for mobile Global System for Mobile Communications (GSM) and Time-Division Multiple Access (TDMA) users. The main benefits of GPRS are that it reserves radio resources only when there is data to send and it reduces reliance on traditional circuit-switched network elements. The increased functionality of GPRS will decrease the incremental cost to provide data services, an occurrence that will, in turn, increase the penetration of data s ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc
