Dissertation,Thesis topics on WiMAX,WiFi,LTE,3G,4G,IP Multimedia Subsystem, Voice over IP, Satellite Communications

Academicians and students have significantly contributed to the field of wireless communications for past many years. A large number of dissertations
and thesis reports have been published incorporating results of laboratory experiments and simulations that have proved to be very useful in
determining the actual performance of the technologies amidst all the marketing claims made by the OEMs and Service Providers. In addition, we should
not undermine the fact that the academic world has been elementary in development of new technologies that have shaped the future of wireless
communications. I want to specifically mention about the development of Wireless Sensor Networking under various projects sponsored by IEEE and
ZigBee Alliance and such other organisations that have finally resulted in open global standards like ZigBee and IEEE 802.15.4 and the company
sponsored proprietary standards like Texas Instruments SimpliciTI and XBee DigiMesh. These technologies employ a number of algorithms/protocols
like ANT COLONY, SPIN, GOSSIP, FLOOD, etc. that have been developed by students of higher studies in wireless communications. In this article, I
hereby present some modern challenges that the students may like to undertake for their forthcoming dissertation and theses research projects:

(A) Advancements in WiMAX and LTE/LTE-A technologies and their applications pertaining to fixed and mobile wireless communications - The
Long Term Evolution (LTE) technology developed by 4G Americas (formerly 3G Americas) is based on the world class HSPA+ (High Speed Packet Access
Plus) technology. Its earlier variant HSPA is the foundation of the widely successful 3G services framework across the world. LTE is perceived to be the
most valid contender of 4G services framework but is facing strong competition from IEEE 802.16e-2005 which is the standard for Mobile WiMAX. How
have these technologies evolved since their inception in mobile and fixed wireless communications? There can be multiple global as well as regional
studies that can be conducted pertaining to this context. One may also like to write dissertations/theses on case studies of world class technology and
telecom services companies that are promoting these technologies - like Nokia, Motorola, Ericsson, Vodafone, Alcatel-Lucent, British Telecom, etc. Some of
the suggested study areas on LTE and WiMax technological evolution are the following:

The above study areas have been proposed keeping the scopes of LTE, LTE-A, and WiMax technologies in mind. However, you may not be able to study
the three technological areas in a single research given their vastness and differences, unless you are conducting comparative studies. Hence, you may
consider narrowing down your topic to a specific technology and its specific scenarios under study. All the above study areas can use models in the
latest academic release of OPNET Modeler by Riverbed Software Inc. through OPNET university program (OPNET has been acquired by Riverbed
Software).

(D) QoS for VoIP over Satellite links - connecting high altitude cities to the metropolitan cities over mobile telephony. - ETCO India has supported
many students on this topic. Later on, I realised that this topic, that had become dormant many years back, is getting active once again due to some
scintillating innovations in high latency VoIP QoS settings for acceptable voice quality over satellite networks. Hence, it is worthwhile to research this
subject area further on many aspects. Regions that are located at very high altitudes (like Alaska, Leh, Laddakh, Tibet, etc.) still find satellite
communications as more reliable compared to terrestrial communications for voice and data connectivity. But the quality of service has always remained
a problem. In light of the new innovations in VoIP QoS (like Packet Segmentation and Re-assembly, Slot Feathering, Single Hop Satellite communications
optimised for VoIP, etc.), they may find a new era of quality of service over satellite communications and hence may communicate better with the world.
Some of the suggested study areas on Satellite communications' technological evolution in the 4G era are the following:

(1) Study of voice codecs and congestion control protocols in VoIP over satellite communications
(2) High efficiency multimedia streaming over satellite links through direct spectrum division and Multi Giga Hertz extremely high frequency bands
(3) Designing and implementation of heterogeneous broadband mobile networking by combining satellite communications at Multi Giga Hertz extremely
high frequency bands with Multi-Gigabit WiFi networks and LTE Advanced
(4) Integrating mobile networks of multiple hill station cities through satellite backhaul connections at Multi Giga Hertz extremely high frequency bands
(5) Mission-critical multimedia applications using satellite communications at Multi Giga Hertz extremely high frequency bands
(6) Effective integration between LTE Advanced and Satellite communications Multi Giga Hertz extremely high frequency bands for mobile networks in
difficult terrains
(7) Mobile satellite backhauls for emergency communications and mission critical news media coverage
(8) Virtualisation of heterogeneous networking using Multi-Gigabit WiFi and Multi Giga Hertz satellite communications at extremely high frequency
bands through Software Defined Networking (SDN)
(9) Network planning and programming for heterogeneous networking using Multi-Gigabit WiFi and Multi Giga Hertz satellite communications at
extremely high frequency bands through Software Defined Networking (SDN)
(10) UMTS and Satellite communications integration with advanced QoS configurations for VoIP
(11) Study of designs and solutions of broadband multimedia content delivery through offloading from Satellite networks with Multi Giga Hertz satellite
communications at extremely high frequency bands to multi-gigabit WiFi
(12) Micro satellite terminals with code division multiple access (CDMA) as broadband access points for Satellite Internet in difficult terrain areas
(13) Satellite communications dispatchers for field access systems in mobile mission critical and disaster relief applications
(14) Adaptive modulation methods and encoding schemes in broadband satellite communications
(15) Digital video broadcasting with QoS guarantee in broadband satellite communications using Multi Giga Hertz satellite communications at extremely
high frequency bands as uplinks and code division multiple access micro satellite terminals at downlinks
(16) Multi-programmed TV broadcasting with user access privileges in a heterogeneous networking environment using Multi Giga Hertz satellite
communications at extremely high frequency bands and offloading to Multi-Gigabit WiFi terminals covering multiple broadband subscribers

All the study areas suggested above in the context of modern broadband satellite communications standards and networking are broad study domains
that comprise multiple narrow topics. All the above study areas can use models in the latest academic release of OPNET Modeler by Riverbed Software
Inc. through OPNET university program (OPNET has been acquired by Riverbed Software). The editable Satellite communications network objects in
OPNET can be used to configure exact existing standards'-based or projected future standards' specifications.

topic suggestions and to discuss your topic.

(E) Applications of mobile technologies - In past few academic sessions, I have realised that students are demanding topics on applications of mobile
technologies in various applications, like - wireless sensor networking, distance learning over Internet (E-Learning), asset management, location based
services, crisis management, transportation, GPS applications, logistics and supply chain management, retail stores (supermarkets and hypermarkets),
vehicle tracking, university campus networking, mobile ERPs/CRMs in corporations, public sector infrastructure projects, healthcare, etc. A large
number of topics can be designed on positioning a specific mobile technology for a specific application, and simulating the same in the laboratory. The
modelling can be done on OPNET Modeler.

(F) Cisco IOS based networking projects employing Cisco Packet Tracer - You can design multiple research topics on accurate implementation of
wireless networks by modelling Cisco products, and configure the entire network by modelling exact product configurations, connectivity and IOS
commands on Cisco Packet Tracer. You can run multiple tests on Cisco Packet Tracer, in exactly the same way as they are executed in real world Cisco
projects. In fact, this approach of doing research is one step ahead of OPNET, at the data link, network and transport layers. The students undergoing
advanced networking courses may find this method very interesting and challenging. Such learning opportunities can significantly help you in your
career as well, because you will be an expert of the latest Cisco configurations and commands for configuring, testing and managing a wireless network.
In addition, the topics will be original because not many dissertation/thesis projects have been conducted using Cisco Packet Tracer. Please contact me
for more ideas on this aspect.

A number of professional researches have been published to address these areas recently. Many of them claim to be unbiased. ETCO India has also
contributed by publishing reports in these areas (ETCO India Published Research Papers). But I personally feel that the academic researchers, that are
known to conduct more unbiased and valid studies, have not yet contributed adequately to these areas. I suggest that students undergoing advanced
courses in wireless communications should develop new topics in these areas and conduct researches for their forthcoming dissertation and thesis
research projects. If all the current challenges are brought to the table, I can visualise hundreds of topics on which the students and academic researchers
can undertake research assignments. Some of these topics have already been undertaken by students but more contribution is required from the academic
world. Tools like OPNET MODELER can be employed to simulate various real life networking solutions to verify the behaviour and performance of
modern wireless technologies in a laboratory environment. I personally like OPNET MODELER because of its capability of simulating real world
wireless products (like Cisco Aironet series). OPNET MODELER academic edition is offered free of cost to students by RIVERBED Inc. under their
university program. The academic version possesses all the features of OPNET except that it can simulate the maximum of 50 million events which is,
however, more than sufficient to simulate any network model created for academic research.
