2.  Objectives
 Challenges
 Modules
 Implemented Architecture
 Internal architecture
 Result
 Conclusion

3.  To interwork heterogeneous networks such as
WiMAX, WLAN and MANET by using IMS
protocol
 Analysis of heterogeneous network without MANET
and with MANET.
 To enhance the QoS (quality of services) for the
above mentioned networks.

4.  Mobility
 Resource management
 Security issues
 QoS
 Power control
 Transport technologies
 Bandwidth scheduling

5.  In the last phase we have completed the performances
of WiMAX-WiMAX-WLAN-WLAN- IMS-interworking
architectures.
 In this phase we have analyzed the performances of
WiMAX-WiMAX-WLAN-MANET-IMS-interworking
architectures.
 Comparison of infrastructure network with
infrastructure less network.
 Providing a QoS(quality of services) to the above
network.

6.  IP Multimedia Subsystem (IMS)
 IMS promises true end-to-end handling of multimedia
applications
 IMS is expected to play major roles in delivering
multimedia content to fourth generation (4G) cellular
technologies.
 IMS-based QoS, is the successful deployment of Voice
over IP (VoIP) on both wired and wireless systems.
 The ability of a network to support high-quality VoIP
calls

8.  It enables high speed fixed wireless communication.
 Brand licensed by the WiMax Forum.
 It is faster to deploy and less expensive and it also
offers operators more flexibility in terms of
deployment time frame and possible installation
areas.
 WiMAX- IEEE 802.16
 It achieves high data rate in part via orthogonal
frequency division multiplexing (OFDM).
 Mobile WiMAX offers high data rate-70Mbps and
long transmission range-35 miles.

10.  Access network support for fixed mobile convergence
of packet switched services.
 Users will require access to operator services from any
location over any access network.
 Users will have multiple terminals and multi-mode
terminals
 Emerging access types require higher bandwidth for
services.
 WLAN uses different frequency spectra from cellular
or PCS, so there is no interference between indoor
WLAN with outdoor cellular/PCS.

12. • Information exchange in a network of mobile and
wireless nodes without any infrastructural support.
• Such networks are often called ad hoc networks to
emphasize that they do not depend on
infrastructural support.
• A mobile ad-hoc network is a mobile, multi-hop
wireless network which is capable of autonomous
operation.
• The purpose of an ad hoc network is to set up
(possibly) a short-lived network for a collection of
nodes.

26.  SIP is the key signaling protocol of IMS. Interworking
between SIP elements of the WiMAX and CSCFs of the
IMS is a key issue in reaching a high level of
interworking betweenWiMAX and 3GPP networks.
WiMAX provides powerful and flexible QoS handling
which can be fully utilized within the current 3GPP-WLAN
interworking specification.
 The overall architecture of the interworking based on
IMS is represented, as well as special issues such as
QoS guarantees and AAA problems are discussed.
