MINIMIZATION OF HANDOFF FAILURE PROBABILITY IN NGWS USING CHMP
Abstract
Next-generation wireless systems (NGWS) integrate different wireless networks, each of which is optimized for some specific services and coverage area to provide ubiquitous communications to the mobile users. In this paper, we propose to enhance the handoff performance of mobile IP in wireless IP networks by reducing the false handoff probability in the NGWS handoff management protocol. The handoff performance of Mobile IP is analyzed with res ....etc

Abstract
The next generation of mobile/wirelesscommunication systems is expected to includeheterogeneous broadband wireless networks that willcoexist and use a common IP core to offer a diverserange of high data rate multimedia services to endusers with contemporary mobile devices that areequipped with multiple network interfaces since thenetworks have characteristics that complement eachother. This requires the provision of seamless verticalhandoff. This paper provides components of anadaptive multiple attribute vertical handoff decis ....etc

Abstract
Self-adaptive management and quality adaptationof multimedia services are open challenges in the heterogeneouswireless Internet, where different wireless access points potentiallyenable anywhere anytime Internet connectivity. One ofthe most challenging issues is to guarantee streaming continuitywith maximum quality, despite possible handoffs at multimediaprovisioning time. To enable handoff management to self-adaptto specific application requirements with minimum resourceconsumption, this paper offers three main contributions. ....etc

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

1. INTRODUCTION
Wireless communication is used for transmission of information from one place to another without using cables. This may be one-way communication as in broadcasting systems (such as radio and TV), or two-way communication (e.g. mobile phones). The research area covers an increasing number of existing and new technologies. The term Wireless came into public use to refer to a radio receiver or transceiver (a dual purpose receiver and transmitter device), establishing its usage in the field of wireless ....etc

ABSTRACT
The steadily growing mobilesubscriber community and their demandfor diversity of service place greatchallenge on the bandwidth utilization,especially in the wireless network part, asradio spectrum is a limited resource.Carefully planned radio usage is criticalfor both system capacity and servicequality. We mainly concentrate on twoaspects of the service provision capabilityof cellular networks in this paper. One iscapacity related that emphasizes the usera ....etc

Abstract”
There are currently heterogeneous wireless access networks. A large variety of applications utilizing these networks will demand features such as real-time, high-availability and even instantaneous high-bandwidth in some cases. Therefore, it is imperative for network service providers to make the best possible use of the combined resources of available heterogeneous networks for connection su ....etc
