(1) Title: Internet access in challenging environments
The Internet applications are widely used in everyday lives of many people. However, the ubiquitous Internet access is very challenging or not available at all in a number of scenarios. These scenarios include travellers on long-haul journeys, people living in remote areas, or when the Internet access becomes disrupted due to a natural disaster. In other situations, the Internet access becomes less stable with occasional disruptions when a large number of users from the same geographical area overwhelm the network. Fortunately, these problems are no longer ignored, and different solutions started to emerge. This tutorial will review the approaches how to improve the Internet access when the access to the network is intermittent, and how to provide the Internet connectivity in the areas where it has been non-existent previously.
In particular, the Internet access for high density users is usually provided by fog and edge computing solutions in order to reduce the requirements for bandwidth to the core network and off-load computing from the cloud servers. These systems also enable to pre-process locally generated data from the IoT platforms, or they rely on information caches. They exploit intelligent protocols to manage traffic demands, and they will play a crucial role in the upcoming 5G networks. However, when the Internet access is unavailable over much longer time scales or permanently, the satellite connectivity is usually assumed. The satellite access is rather expensive and bandwidth limited, and the coverage may be restricted to certain geographical areas and time of the day. Nevertheless the satellite networks are already planned for the Internet access to travellers on long-haul flights. On the other hand, in order to provide the Internet access to people in remote areas, the current thinking involves a network of high altitude platforms including the stratosphere balloons.
In this tutorial, we will critically review the current developments including notable projects to understand the key drivers and existing or proposed network and application architectures to provide the Internet access in challenging environments and conditions. We will compare the most promising strategies against other existing networking concepts including information caching, delay tolerant networking, content-centric networking, and the content distribution networks. This allows us to define the requirements for the network architecture and networking protocols. We will also consider operating systems, user interfaces and the developments in web applications. We will examine physical delivery of information contents and portable clouds as a promising concept which can resolve many issues in situations with limited or no connectivity. We will also discuss the implementation challenges, and issues related to energy supply, security, content creation and update, and overall system deployment and maintenance.
Part 1: Accessing the Internet when the connectivity is limited
- Current developments focusing on long-haul travellers
- Current developments focusing on digital inclusion of people in remote areas
- Key issues, challenges and drivers and how they are going to influence 5G development
Part 2: Web technologies for the limited connectivity
- information caching, delay tolerant networking, off-line and progressive applications
- edge and fog computing, cloudlets, content distribution networks
- information-centric networking and portable clouds
Part 3: Case study: Designing the Internet in remote areas of Himalayas
- portable clouds, physical information delivery, selection of the information contents
- implementation and maintenance challenges: energy supply, antennas, coverage
(4) Learning objectives:
- understand the importance of considering the Internet access when the connections are limited or unavailable
- understand the current trends in providing solutions for the Internet access with limited or no connectivity
- introduce a new concept of portable clouds which may solve many challenges of using the Internet in situations where there is no Internet access available
- promote the current work of Dr. Mahabir Pun and gain more support for his activites
(5) Duration: the overall length 3.5 hours consisting of 3 hour of lectures and additional 30 minutes for one or two breaks in between
The proposed tutorial is intended to be attractive for current PhD and other research students and academics who are interested in modern networking concepts. There are estimated 4.5 billion people on this planet who have no Internet access, many of them being in the south Asian countries. The presentations will be kept at a moderate technical level to be accessible by those who may not have enough knowledge in networking, and at the same, the presentations will be made attractive for networking experts by highlighting the latest developments in this area. We will identify a number of open research problems, and also discuss our collaboration with Dr. Mahabir Pun who is actively developing a number of projects to improve living conditions for people in the remote areas of Nepal.
Dr. Pavel Loskot has an extensive portfolio of industrial and academic collaborative projects. He has been involved in telecommunication research and development since 1996. His current research is concerned with network engineering and cyber-physical system design in telecommunications, transport, and energy sectors. He received two best paper awards in international conferences, served as a TPC member in over 70 IEEE conferences, and delivered the keynote speeches and tutorials in a number of IEEE conferences. He is a Senior Lecturer in System Engineering at Swansea University, UK, and the Senior Member of the IEEE.
Pavel Loskot is currently heading a group of 6 research students. Some of them may accompany him to the conference and help him to deliver the tutorial:
Mr. Salman M. Al-Shehri has 20+ years of experience in designing, deploying and operating wireless ad-hoc networks in challenging environments. He is expert in antennas and protocols for these networks, and how to evaluate the wireless networks using computer simulation software such as OPNET and NS2.
Mrs. Murooj Nadhom has background in edge and fog computing systems, and is currently researching portable clouds and how the Internet is used by different people in different parts of the world.
Mr. Ramhari Poudyal is researching renewable energy systems, how these systems can be designed for use in remote areas, and they are going to affect the overall economic development of the countries.
