In this paper we investigate the problem of voice communications across heterogeneous telephony systems on dual-mode (WiFi and GSM) mobile devices. Since GSM is a circuit-switched telephony system, existing solutions that are based on packet-switched network protocols cannot be used. We show in this paper that an enabling technology for seamless voice communications across circuit-switched and packet-switched telephony systems is the support of digital signal processing (DSP) techniques during handoffs. To substantiate our argument, we start wi ....etc

Impact of Node Mobility on Routing Protocols for Wireless Sensor Networks
G. Santhosh Kumar, M.V. Vinu Paul and K. Poulose Jacob
Abstract”
1
Wireless sensor networks monitor their
surrounding environment for the occurrence of some
anticipated phenomenon. Most of the research related to
sensor networks considers the static deployment of sensor
nodes. Mobility of sensor node can be considered as an
extra dimension of complexity, which poses interesting
and challenging problems. Node mobility is a very
important aspect in the des ....etc

Introduction

Wireless system have been developed in an evolutionary way,ie,generation by generation over the last 20 years.
1G system is of diminishing importance.
The dominant generation are 2G,2.5G with 3G coming into use.
Pilot research has been targeted to the next generation.
One feature of next generation is the heterogeneous communication environment.

SEAMLESS MOBILITY
ABSTRACT
The new trend in communication is that everyone needs to be wireless and prefer mobile communication and PDA's. The present service providers fail to provide all type of communication like GPS, INTERNET..etc. Wireless Local Area Network Seamless Voice and Data Solution is a complete end-to-end enterprise communications solution that can lower communications costs, increase user efficiencies and create new capabilities. The solution will converge wired and wire ....etc

Abstract
Opportunistic networks are wireless mobile networks in which a continuous end-to-end path between a source and a destination is not necessary. Messages are stored at intermediate nodes, and opportunistically forwarded when a more suitable next hop towards the destination becomes available. A very interesting aspect understands how usersâ„¢ mobility patterns impact on the performance of routing protocols. Starting from this motivation, in this paper we take into consideration group mobility models, whose movement ....etc
