Dear researchers,
Let's share our opinion about recent attractive topics on communication systems and the potential future directions.
Thanks.
I think, recent topics will focus on 5G, the Internet of things and more researches on the development of fiber optic communication
Dear Mohammad Dehghani Soltani, the current hot and interesting topics in communication systems are shown on my poster. The sources of literature with links to all the topics shown in the poster can be found in Part "18 Networking Trends" in the book "Technology of the IP Networks" (see german) - see the address: https://www.researchgate.net/publication/331651693_Technik_der_IP-NETZE_-_Internet-Kommunikation_in_Theorie_und_Praxis Best regards and much success Anatol Badach
The folks about 6G at this point in time are a bit too earlier. It's quite difficult to mark one topic as a trendsetter for future research in communication. It can be a matter of personal choice. However, if we need to choose one, it should undoubtedly be "Internet of Things" as it evolved a range of future research directions and surrounded by several other areas in communication directly or indirectly including, but not limited to, 5G, Artificial Intellegence and Machine Learning, Cloud and Edge Computing to name a few.
I think underwater wireless optical communication & indoor optical communication system (Li-Fi) consider hot and interesting topics in communication systems
IoT systems, 5G systems, heterogeneous wireless systems (combination of Wi-FI, 3G 4G and 5G).
You should look at the ITU-T FG Net2030. They hold workshops with free access to presentations.
The objective is to prepare the networks needed by 2030...
Questions asked:
-latency below 1ms?
-IP protocols or not?
-most challenging use cases which today's network cannot address
Well, AI. or UAV-aided communication (aerial base stations, gathering data from sensors, mission-aware path planning etc). I recently gave a tutorial @ ICC'19 you can have a look to the slides
Presentation Tutorial: Wireless Communications with Unmanned Aerial Vehicles
Hello everyone.
From my point of view, the topics that are focused by many universities including 5G enabling technologies such as a wireless software-defined network, network function virtualisation, millimetre wave spectrum, massive MIMO, network ultra-densification, big data and mobile cloud computing, scalable Internet of Things, device-to-device connectivity with high mobility, green communications, and new radio access techniques
OPS (Optical Packet Switching) allow a Optical Network works like a Computer Network.
Edge Computing! Look at ETSI-ISG-MEC, it provides ways to alleviate the burden of network load, by keeping all computation possible upstream of transmission
Wireless communication has come up with more challenges than ever because of its exciting application possibilities.
5G, UWB, Cognitive radios etc. have become keywords in communication domain.
The real challenges being faced are due to coexistence of multiple RF bands. The most suitable bands, as per the researcher, may not be implemented due to non-availability of devices and components. Another challenge is to design radio receivers and transmitters with very wide bans. ZIF receivers are difficult to design at the high end of the spectrum.
The problem of interference is always there and unless it is solved with utmost precision, V2V type applications cannot be launched.
Hence, the challenges are many as well as the prizes for solving the issues.
Network slicing across multiple telecom operators domain. Network slicing transfers to the B2B customer of the operator not only the transmission resource, but the control plane layer, and visibility for monitoring what is happening in real time.
It is critical, and difficult because it touches the core network operation of an operator, albeit in a virtual form.
I think, recent topics will focus on 5G, the Internet of things and more researches on the development of fiber optic communication
Properties of materials depend on the potentials of their molecules. SImilarly, characteristics of wireless networks depend on the characteristics of their low energy EN-channels (PHY layer).
Their energy-spectral efficiency, bit rate, BER, range, complexity, cost, energy consumption, lifetime, resistance to external disturbances, etc., influence the performance of overall network. Not vice-versa.
This stresses the importance of PHY layer research, and there is a lot of work.
A relevant topic is the Internet Capacity Crunch, that is the imminent exhaustion of network resources into the backbone's optical networks.
The penetrations of radiofrequency were increased specially at 5 offspring of phone cell of mobile because the modulation in order to raise the speed of internet needs increasd in frequency . Often frequency near gega Hertz about 2.45_30 GHz
Specific to wireless communication:
In-band Full Duplex, Massive MIMO, Non-orthogonal multiple access systems, Spatial modulation, Internet of Things, Machine learning applications in wireless, millimetre-wave communication, Energy-efficient systems in cellular and so on.
Visible light Positioning, machine learning applications based on VLC
5G along side SDN attractive topics on communication systems and the potential future directions.
5G SDN is emerging field
"SDN is redefining the network architecture to support the requirements of the forthcoming 5G ecosystem—5G SDN will play a crucial role in the design of 5G wireless networks"
https://www.sdxcentral.com/5g/definitions/5g-sdn/
Conference Paper A Research Survey on Software Defined Networking (SDN)
Hi all, I suggest the recent hot exist in the catalogue in any system of comunication
Network infrastructure evolution for the 5G era:
-how the optical fibre infrastructure carry traffic to/from wireless use (in-car, pedestrian, etc)
-network slicing: virtual management of network portions to third parties by telecom operator. One issue is how this works across borders and domains.
-IoT use case for URLLC, ultra reliable low latency communication.
-deeper theme: every network node has triple function (data, compute, network). Edge Computing has delivered an optimisation strategy path to ensure optimal use of network (say network offload under multiple angles). Optimisations for data (data management, storage, retrieval, enforcement of data policy like GDPR) or optimisation for computing (distributed computing, algorithm, micro data center with energy and timing efficiency gains) is still an open field: great for PhDs. Let me know, I would be glad to offer more detailed thoughts.
Does it help?
I think the interesting topics are Smart Antennas and 5G communication
Hello Mohammad Dehghani Soltani ,
I see that using the principles of wireless communications in Self-Driving Cars is becoming very popular. For example, people use LiDAR sensors for detection and ranging of vehicles in the roads. Making the wireless technology cheaper, accurate, and enabling safety in this area will be some of the open and important questions.
Secondly, with the advent of COVID-19, I do speculate that investments in the field of medicine will grow rapidly. Wireless technology connected with medicine is becoming an ever-green area where people usually prefer using VLC based communication. It looks like Internet of Medical Things (IoMT) Sensors, RFID, and other similar areas will play a major role in this area. In the light of this, 5G and Beyond cellular technologies will be an important aspect regarding the connectivity between IoT devices over the given bandwidth.
Security will be a very important area to explore, especially in IoT applications where the person's data should be prevented from reaching unauthorized personnel. Robust algorithms and designs in the transmitter and receiver will be required to overcome this issue.
Low-power IoT devices will also be an interesting area to work on which will be suitable for many applications. This is related to having energy-efficient and smart systems as mentioned by Anatoliy Platonov.
Dear K. Suresh, Thanks a lot for your comprehensive suggestion, which I believe it will help not only me but also other researchers.
Dear Mohammad Dehghani Soltani and everyone,

It was asked one year ago, what did you finally choose Mohammad Dehghani Soltani
Thanks Nitin Gupta for your interest! I am currently working on indoor optical wireless communication to support high-data-rate communications.
In addition to all previous topics including visible light communications, LiFi, etc. I think the time is for merging the all-optical wireless technologies together as well as with RF technologies to design real hybrid networks.
I absolutely agree with Hossien Eldeeb . It is the need of time to start looking at the hybrid solutions to exploit the best of all.
Thanks Husnain. If that's is possible we could create a group and joint together for such work. Let's see who will be interested and ready to join for this team.
it's a great idea, I think. I am definitely in and happily available to lead the activities in this domain. It would be even better if we join hands with others having expertise in different domains. Hossien Eldeeb
LEO Constellation satellites are interesting topic now especially after the newly deployed systems
Let's collect who would like to join, then assign meeting to arrange the structure and tasks for each one.
Sure @Elhamsadar Anarakifirooz.
We will assign time for meeting in few days.
Hossien Eldeeb : This might be helpful: https://www.toucan-network.ac.uk/
My PhD project.
A week ago, I saw the much longer and sufficiently interesting discussion on the topic. Is the current discussion its continuation, or is independent one?
Hi Anatoliy Platonov , if you mean the discussion about hybrid networks, Hossien Eldeeb is handling it. He can suggest how it is going on.
Hi
I think the hybrid networks of recent promising technologies that expected to fulfill the requirements of 5G and beyond like D2D communication, VLC, C-RAN, UAV, IoT and UDN.
It might be of your interest:

Hello Mohammad Dehghani Soltani
Li-Fi technology is represents one of the most important topics that can be expanded upon.
I did research in this field and the aims of the study were to design a high-speed communications system to transfer data using All optical OFDM technology.

An interesting topic - Intelligent Reflecting Surfaces targeting 6G communications - https://www.youtube.com/watch?v=R583PV-uQFM
The great and almost untouched field of research and applications is the information theory for the communication systems with feedback channels. It allows the design of not complex and noise - resistant systems which transmit signals from the end nodes with the limit energy - spectral efficiency using only adjusted AM modulators.
Important: all end nodes of networks (including IoT) communicate with the base station over forward and feedback channels. Currently, feedback is not used for the improvement of the forward transmission efficiency.

This discussion is one of the interesting one with different view based upon the research activity. As per my research work, I can suggest VANET with 5G or 6G, UAV, or, Application based on IoT, etc....
There could be more than one areas:
1. Free Space Optics
2. Signals and systems in relation to fading channels
3. Reliable Drone communication
1) Network slicing is very promising: it allows to create "areas of service/resource" within operator core networks, and transfer some management to "end users" (organisations with a significant IT department).
This could go well into "beyond 5G"
2) Non Internet Protocol developments may also help break the glass ceiling of legacy internet, and in particular crossing the "sound barrier" of the time granularity below 1ms

Dear Ljubomir Jacić , thanks for sharing this information with us.
Dear @ Mohammad Dehghani Soltani
OWC for satellite applications is one of the hot topics.
one can research more on software define network and their application
Thanks for your question and great to exchange the ideas...
With the tremendous developments in the wireless communications, particularly with applying 5G and the trends which are planning for the generation beyond, I think the hot topics will be Artificial intelligent with the related algorithms with IoT.
It may be MIMO, MOBILE EDGE COMPUTING, both battery driven and energy harvesting enabled reliable communication, network slicing, virtualisation etc. are the most important topics right now.
5G systems and the pillars of 5G are hot topics in communication. Energy efficiency (i.e., SWIPT, WPCN), Low latency, efficient spectrum utilization techniques (full-duplex communication systems) are all very popular now a days. 6G networks are also pacing up in the race now. The application of machine learning, deep learning and artificial intelligence in communication systems is also good topic to work. IoT and MTC networks and free space optical communication for short range networks is also future studies.
