Abstract - An Wireless networking is becoming an
increasingly important and popular way of providing global
information access to users on the move. One of the main
challenges for seamless mobility is the availability of simple
and robust vertical handoff algorithms, which allow a mobile
node to roam among heterogeneous wireless networks. The
objective is to determine the conditions under which handoff
should be performed. Nowadays mobile handsets are capable
of having different network interfaces. There are multiple
criteria for handoff in NGWN. Handoff decision algorithm
decides the optimal target network by considering a set of
decision parameters including available bandwidth, velocity,
throughput, monetary cost, security and user preference. One
of the technical challenges with this integration and
interfacing of heterogeneous wireless networks is handoff
decision that is used to choose the optimal network depending
upon the type and service requirements demanded by the
user’s application. Heterogeneous wireless network will be
dominant in next generation wireless networks (NGWN).
Increasing user demands and the growing interest of service
providers to offer diverse applications have motivated the
integration of heterogeneous wireless networks which enable
the users to move seamlessly across different types of networks
and to enjoy anytime, anywhere services.
Key Words: Mobility management, Next generation
wireless networks, Media independent handoff, Vertical
handoff management.
1. INTRODUCTION
There has been tremendous changes taking place in concern
to network landscape, recently most of the homogeneous
networks are changed to heterogeneous networks. The
reason behind this is, due to the innovation of multimodal
terminal devices that has the ability to support more than
one type of network with multiple interface capability.
Handoff is the method by which a mobile node can move
logically within the network environment without any
service interruptions and keeps its session active while on
the move Handoff execution is initiated by the selection of
access network only when the strength of signal from the
base station goes down or the base station is unable to
provide service as per the users requirements.
Crowded scenes have been more frequent in the real
world because of increase of population and variety of
human activities. Due to increase in popularity a crowded
scenes analysis is an area of interest to scientists in the
recent times. It brings out massive challenges to public
management, security or safety. In the last decade,
automated scene analysis has already pulled much research
attention in the computer vision community. In case of
crowded scenes, the problems cannot be handled well due to
the large number of individual participation. These
individual not only cause the detection and tracking fail, but
also greatly increases computational complexity. Under such
circumstance, crowded scene analysis as a unique topic, is
specifically addressed.
Different types of Next generation wireless
networks such as GPRS, LTE, WiMAX and WLAN are brought
together to form a single wireless network environment the
reason behind this is that a single type of network or an
homogenous network hardly could satisfy different need of
services required by users and diverse applications. Each
network has its own ability to support different kinds of
application and services with different quality of service
requirements [1].
In order to overcome such drawbacks and gain
benefit from the diversity of different technologies these
next generation wireless networks are brought to form a
single network and support such diverse application and
maximally satisfy users needs.
Selection of the optimal network among available
networks is one of the challenging tasks because several
criteria’s and parameters involved in it such as service type,
network condition, system performance and user
preferences for making the decision.
Selection mechanisms are of three types those
under user control, network control and cooperation of both
[1]. Handoff can be classified as vertical and horizontal and
further classified on who controls the handoff decision [8].
All these factors make the decision making more complex. A
new network selection scheme that explicitly takes into
account user preference, available network parameter and
quality of service requirements for selecting the optimal
network is proposed here. IEEE 802.21 MIH framework is
used by the proposed system for creating the heterogeneous
network environment, information gathering and handoff
initiating. In the proposed system, different parameters are
acquired by using different System Access Points ȋSAP’SȌ
