Scientific researchers over the years have made significant contributions to the field of wireless communications. A large number of dissertations and reports of dissertations were published, in which the results of laboratory experiments and simulations were presented, which turned out to be very useful for determining the actual effectiveness of technologies among all the marketing requirements made by OEM-suppliers and service providers. In addition, we should not emphasize the fact that the academic world was elementary in the development of new technologies that shaped the future of wireless communications. I want to specifically mention the development of the Wireless Sensor Networking network under various projects sponsored by the IEEE and the ZigBee Alliance, and such other organizations that were finally covered in open global standards such as ZigBee and IEEE 802.15.4, as well as sponsored by proprietary standards such as Texas Instruments SimpliciTI and XBee DigiMesh. These technologies use a number of algorithms / protocols, such as ANT COLONY, SPIN, GOSSIP, FLOOD, etc., which were developed by students of higher educational institutions in the field of wireless communications. In this blog, I hereby propose new tasks that students must undertake in order to support the evolution of trends for new technologies that are involved in some kind of technological war around the world. Some of the problems requiring the attention of a scientist are:
(a) Positioning WiMAX and LTE in fixed and mobile wireless applications. Is IEEE 802.16e-2005 successful, like IEEE 802.16d-2004, in light of the competition with LTE?
(b) TTR-R2 versus LTE - do they end up in another technological war in the future?
(c) Who will win the race to become current 4G technology - LTE or WiMAX or Both?
(d) Will the IP multimedia subsystem lead to daylight on the world's largest telecommunications markets — for example, in India and China?
(e) How will IEEE 802.11n be fair against its predecessors and WiMAX for internal wireless applications?
(f) What happens to the large number of IEEE 802.11n-certified WiFi Alliance products after IEEE 802.11e certification for true QoS implementation (with both EDCF and HCF)?
(g) Is wireless IP multimedia evidence of synergies between several technologies - Wi-Fi, WiMax, 3G and LTE?
(h) Will the dream of a global location server for SIP addresses of mobile phone users be realized, regardless of the country and service provider?
(i) How are SIP-based wireless solutions and IP v6 address space approaching?
(j) Positioning 4G competitors on user devices — laptops, PDAs, handhelds, tablets, mobile phones, iPods, etc.
(k) Positioning WiMAX and LTE as backhauls - can they replace optical fibers?
(l) QoS for VoIP via satellite communication channels is the only solution left to connect high-rise cities to capital cities via mobile telephony.
A number of professional researchers have recently been published to solve these problems. Many of them claim that they are impartial. But I personally believe that academic researchers, who are known to conduct more objective and reliable research, have not yet made a sufficient contribution to these areas. I suggest that students taking advanced training courses in the field of wireless communications should develop new topics in these areas and conduct research for their future dissertation and research projects. If all current calls are listed in the table, I will be able to present more than 100 topics on which students and academic researchers can perform research tasks. Some of these topics are already stated by students, but more input from the academic world is required. Tools such as OPNET IT GURU and OMNET ++ can be used to simulate various network solutions for real life to test the behavior and performance of modern wireless technologies in the laboratory. I personally like OPNET IT GURU because of its ability to imitate real-world wireless products (for example, Cisco Aironet series). But OMNET ++ provides more flexibility due to its programming interface. The OPNET IT GURU Academic Edition is free to Opnet Technologies Inc. students. as part of their university program. The academic version has all the features of OPNET, except that it can simulate a maximum of 50 million events, which is more than enough to model any network model created for academic research.
