Quantum Telecommunications Demystified
Introduction There is considerable concern that quantum computing will make existing communications security protocols obsolete. In particular, Public Key Infrastructure (PKI) methods are believed to be vulnerable using the Shor algorithm. This article seeks to familiarize the readers with the new quantum-based technologies and explore their impact on telecommunications, such as PKI. There is much…
The IoT and the Serious Security Risks It Poses
Introduction The Internet of Things (IOT) refers to the increasingly networked world we now inhabit, in which more and more “smart” devices use Internet to interact with other devices, servers, or with various users. It is not a new type of Internet, but an evolutionary development that shows how incremental technology growth can lead to…

Distributed Computing for IoT: Data Management in a Fog Computing Environment
Mobile cellular operators are making plans for Mobile Edge Computing (MEC), which enables Cloud computing capabilities and an IT service environment at the edge of the cellular network. It is a concept developed by ETSI (European Telecommunications Standards Institute) that aims to bring computational power into Mobile RAN (radio access network) to promote virtualization of software at the radio edge. MEC brings virtualized applications much closer to mobile users ensuring network flexibility, economy and scalability for improved user experience.

Blockchain and Other Cutting Edge Tech
Blockchain, the Distributed Ledger Technology behind Bitcoin, has attracted interest across many industries including financial services, legal, real estate, digital rights, identity management, healthcare, asset tracking, supply chain management, and the Internet of Things (IoT). A disruptive technology, it has the potential to transform the way many transactions are conducted.

The Internet of Things (IoT) Revolution: Are You Ready?
Nearly every industry vertical stands to be transformed by the coming IoT revolution. The IoT technology is creating enormous opportunities for new services as well as more efficient delivery of existing services. The rapid pace at which this technology is evolving is also giving rise to major privacy/security risks for individuals, institutions, and public infrastructure — creating new vulnerabilities and giving rise to not-as-yet-thought-of attack modalities, including those of remotely engineered death and destruction.

SDN/NFV (Software Defined Networking, Network Functions Virtualization): Networking Game Changers?
The terms SDN (Software Defined Networks) and NFV (Network Functions Virtualization) have acquired magical connotations for those who work with networks but are not technical, raising many expectations. Are SDN and NFV really such a game changer for networking? SDN and NFV are among the half dozen or so technologies seeking to address the issues that trouble contemporary networks. The other major technologies in the mix include GMPLS, ASON, high-speed Ethernet, NGN, and OTN, with a good deal of overlap between the various solutions that have been proposed.

The Internet of Things: Smart Devices, M2M, WSNs, and IoT
At its most basic level, IoT just connects simple devices over the Internet or other network which could be private and/or wireless. Common examples include the ‘program-from-anywhere’ thermostats and security systems already in use. At the mid-level, IoT is an enabler of new business and technology models, not just incremental improvement of existing ones. For example, autonomous vehicles will require very high levels of communication among devices in the vehicle (e.g., LIDAR, sensors, cameras, computers) and most likely devices/sensors outside the vehicle (e.g., other vehicles, fixed cameras, servers with detailed maps). At the highest level, the interconnection of devices could lead, over time, to new technologies that will reorganize the society, much as the automobile and the Internet have. One possibility is the “Smart City”, where IoT is used not only in autonomous vehicles, but where all types of transportation are linked to provide optimized people movement. Private self-drive cars, in this scenario, would rarely be needed. This could lead to entirely different land use patterns, for example.

SDN/NFV: Enhancing Network Capacity and Functionality
SDN and NFV have been developed to help meet the challenge of increasing demand for services and user expectation of rapid provisioning and universal availability. Both rely on virtualization, the ability to make a piece of equipment look like another via the magic of software. SDN was originally developed to address the problems of large data centers, where virtualization of hardware and operating system is important. It will likely spread to other areas, including the WAN, where virtualization and the ability to dial up bandwidth and related characteristics would be extremely valuable as well. NFV is an outgrowth of SDN in many respects, concentrating on backbone networks, where the need to rapidly reconfigure resources is key.

Mobile Backhaul “Mutual Fund” and Technology Trends

MOOCs: A Revolution … or Just Plain Hype?
As of this writing, hundreds of MOOCs are being offered by US and foreign universities and millions of people have registered for them. But are they effective? They have been criticized for their lack of academic rigor. They also suffer from poor completion rates, with the bulk of participants dropping out in the first few days of the course. But they do offer the promise of making higher education and degrees accessible to a much larger chunk of the world’s population at a fraction of the cost, significantly reducing the cost of corporate training, and providing a convenient and cost-effective option for lifelong learning.
Mobile Backhaul: The Missing Link
Mobile is hot and mobile backhaul is thriving. As the number of mobile devices grows the need to bridge the gap between the subscriber devices and the IP cloud grows and as the bandwidth demand increases the demand for a bigger bridge between the subscriber devices and the IP cloud also grows.
Statistical Tolerance Analysis
Dimensional tolerances specify allowed variability around nominal dimensions. We assign tolerances to assure component interchangeability while meeting performance and producibility requirements. In general, as tolerances become smaller, manufacturing costs become greater.

TRIZ: How to Stimulate Engineering Creativity Using TRIZ
TRIZ is an acronym for teoriza rezhinija izobretatalskih zadach, or the theory of inventive problem solving.

After reviewing 40,000 patents, Altshuller reached the following conclusions: Inventions and innovations follow common patterns that cut across industry and technology boundaries.

Unleashing Engineering Creativity
Creativity. We deem it essential for business and technical success, yet we are often puzzled about how to find it, how to empower our people to exercise it, and how to apply it. Do we need creativity for solving engineering or business problems, designing completely new products, improving existing products, or developing and improving processes? Are we born with creativity, or do we need to develop our creativity skills?
