When it comes to the Internet of Things (IoT), cities have enormous potential. A city needs to manage many different processes and priorities ranging from trash collection to traffic management, for hundreds of thousands to millions of people distributed over a large area. Many of these processes can be enhanced through the use of IoT.
During the past several years we have seen more and more technology solutions being deployed to help cities optimize these processes and provide additional value to its citizens. Smart parking is perhaps one of the best known and perhaps the most visible for city inhabitants.
Typically an IoT solution stack for these processes is build on several layers: (1) sensors to measure, (2) for each type of sensor there is typically a compute infrastructure at the edge of the network near the sensors, to perform simple aggregation, protocol/access technology conversion and local processing/analytics, (3) connectivity (wireless, backbone) to transfer data to the cloud, (4) cloud for deeper analytics, business processes and long term data access.
No two cities however are the same and each city has its own unique challenges. Backbone network infrastructures are managed in different ways, and local views on privacy and security can differ substantially. Light poles form a natural infrastructure to connect sensors with the edge of the network as it provides power and physical security. However cities upgrade their physical infrastructures with different time tables, and upgrades take time (and money), which leads to different alternative IoT infrastructure deployments at the network edge. Each city is organized differently which means budgets are managed differently. The latter can be especially challenging if new services touch multiple departments.
But cities also face common IoT challenges. Different types of sensors typically come with their own edge hardware and service management software. If a city deploys multiple sensor platforms this leads to so-called box proliferation and service management siloes (what some people call the vertical approach to IoT). This is not only undesirable from an aesthetics point of view, but makes it harder (more costly) to manage the whole city IoT infrastructure.
Challenges edge services
More sensors also means an increased security risk. Certain sensors have little processing power (to save money and battery life) which can make them targets for security attacks. While network security can filter out a lot of attacks there is still an increased risk of infecting the whole city infrastructure, specifically on an application level through data obfuscation. Sensor platforms do offer a certain level of security, but it is not always the primary focus within the solution and dealing with multiple platforms leads to multiple different security solutions.
The above challenges make it harder to scale up IoT in cities. Therefore a paradigm shift is needed towards a hyper distributed architecture of smart nodes: The heterogeneous edge hardware and software platforms should be replaced by a platform on which the virtualized services of the providers can be deployed. This so-called fog platform has hardened security as well as common libraries, features and hardware that can be used by the service providers to deploy their virtualized edge services. The fog platform also provides uniform edge service life-cycle management, policy based data and service access, as well as multi tenancy, reducing the cost for a city to manage such an infrastructure.
Fog: a platform to reduce cost, increase security and amplify IoT
The fog platform is a win-win for the city and its edge service providers. Service providers can focus on their core competence of sensors, data aggregation/processing and business logic while leveraging standard security and processing features from the fog platform as well as the possibility to easier share and combine data (sometimes referred to as the horizontal approach to IoT) between different services.
For the city, the fog platform will make it easier to manage and deploy new edge services, without adding new boxes on the network edge for each new service, thereby reducing the capital and operational cost for managing the city IoT infrastructure.
The value of the fog platform for a city is not only the direct operational and capital cost savings as well as hardened security, but equally important is the shorter deployment cycle of new edge services, and easier data sharing between the traditional service siloes. With such an approach the city can become a large distributed test-bed to incubate new innovative ideas on data fusion and processing and develop new services that contribute to the overall quality of life for its citizens.

Call me an optimist.
We are fortunate today to watch the dawn of the Digital Experience era as the world becomes digitally more and more connected.
Consider that there are already 3 billion of us connected to the Internet. Imagine what the next 4 billion can help us do as they connect.
Even greater change could result as the everyday “things” around us – bus stops, parking spaces, and street lights – get connected. I’ve seen predictions that 20, 50, even over 200 billion more things will be connected in the next couple years. Just think of the tremendous possibilities that could result from that amount of connectivity and collaboration happening around this planet.
What’s rapidly unfolding before us is the Internet of Everything – the intelligent connection of people, process, data, and things. Studies show that the Internet of Everything can drive $19 trillion worth of economic benefit for this planet. To put that into perspective, that’s almost as large as the U.S. and China economies combined. What is your country’s, community’s, or business’ portion of that?
But what fuels my optimism are the social, cultural, and environmental benefits waiting on the horizon — if we accelerate and if we change. With more efficiency and less waste, we human beings can benefit, as can our planet.

What does your #CityofTomorrow look like?
Over the past decades, broadband Internet access has been an important enabler of economic growth, social inclusion and improved government services. Now, the latest phase of the Internet—the Internet of Everything (IoE)—is transforming our lives in whole new ways. The biggest impact of this change is happening in our cities.
At this year’s Cisco Live in San Francisco, there was a lot of discussion around the idea of digital cities. New ideas that combine smart phones, cloud applications, data processes with whole new classes of connected devices are reinventing city services and experiences. This is the Internet of Everything in action: transforming every aspect of a city, from utilities to public safety to transportation.
There are many examples today. The city of Santander in Spain has installed sensors to monitor traffic levels, noise pollution and lighting levels. Santander’s smart parking application has yielded an 80 percent reduction in downtown traffic congestion! Cities around the world are using the Internet of Everything to reinvigorate urban centers just like the one in Santander, which can adapt to residents’ needs in real time. These cities are discovering new opportunities for energy efficiency and seeing immediate returns on investments.
Another IoE twist is the Los Angeles police department project using data analytics to more rapidly spot crime in progress, via license plate readers on police cars. These readers, which are in use as officers conduct normal business, digitally scan tens of thousands of vehicles over the course of a single day. This means automatic notification of stolen vehicles to officers as they drive past on their routine patrol.
,Want to hear more? Cisco has teamed up with CNN to explore digital cities around the globe, just like Santander and L.A. The CNN “City of Tomorrow” looks at how cities are utilizing technology to improve our lives, diving into unique case studies with results happening today. Weekly editorials on CNN broadcast television and the City of Tomorrow hub showcase IoE examples happening around the world. Just as L.A. becomes a safer place to live, San Diego is able to increase the amount of available drinking water, and Seattle has created a completely green commercial building that leaves no carbon footprint. These are only a few examples of IoE in action; there are many more on the horizon. And you can learn about them all in this eight-week City of Tomorrow series.
What you might not have realized is that the Internet of Everything is changing things in your city, too. How are you using the Internet of Everything today?
We want to know what examples of the Internet of Everything you see in your own City of Tomorrow – your neighborhood! Join the conversation online by tagging your photo and video examples with #InternetofEverything and #CityofTomorrow. How is the Internet of Everything changing your city?

For centuries, cities have generated most of humankind’s art, religion, culture, commerce, and technology. And while this trend is expected to continue, several challenges are emerging, including stress on aging public infrastructures, limited success of public-private partnerships, reduced budgets, and the loss of “brain power” to fast-growing suburban areas.
To revitalize the world’s largest cities, City24/7—a company committed to making public communications more accessible to everyone, everywhere—in collaboration with Cisco IBSG and the City of New York, has launched an interactive platform that integrates information from open government programs, local businesses, and citizens to provide meaningful and powerful knowledge anytime, anywhere, on any device. In short, City24/7 delivers the information people need to know, where and when it helps them most.
Located at bus stops, train stations, major entryways, shopping malls, and sports facilities, City24/7 Smart Screens incorporate touch, voice, and audio technology to deliver a wide array of hyper-local (about two square city blocks) information, services, and offerings in real time. The Smart Screens can also be accessed via Wi-Fi on nearby smartphones, tablets, and laptop computers.
The overarching goals of the City24/7 Smart Screens are to inform, protect, and revitalize. Read More »
