Traffic lights (TLs) are used to control traffic at road intersections. Typically, the TL control mechanism on the road operates according to a fixed periodic schedule to change the light (red/yellow/green). A different schedule may be employed at late night or early morning hours. Such fixed light control does not react to changing traffic conditions, and is unaware of (unresponsive to) congestion...
Paper deals with the smart city and smart public lighting concept and their characteristics. Furthermore, it deals with public lighting management system capabilities and interoperability between more public lighting systems, with possibility of implementation of standardized system for public lighting management in terms of smart city concept. Different manufacturers of public lighting use a lot...
The Smart Cities concept implies the integration of vertical application pillars, such as mobility, smart grid and public illumination, and more, for an optimal management of the resources and a reduction of the energy footprint of large cities. This approach requires the use of existing heterogeneous communication infrastructures to allow a peer to peer interconnection of services exposed by sensors...
The Indian ‘smart cities’ have burgeoning population consuming the intelligent systems running over the city infrastructure and services. One critical set of such services is that of the emergency services involving Ambulances, Police and Firefighters. The services provided by these officials are often time critical, which makes their easy and quick availability a must have attribute. This paper proposes...
Evolving methodologies are seamlessly connecting the real world and the virtual world using some physical objects and intelligent sensors. Internet of Things (IoT) is one such methodology. Things are becoming smarter than before. IoT empowers users to communicate and control physical devices to salvage vital information. Large amounts of data will be generated and exchanged which in turn will help...
With the recent advancements in the information and communication technologies, large number of devices are connecting to the Internet, hence large volumes of data in different formats and from different sources are generating. Consequently, on one hand dynamic and heterogeneous data sharing and management, in the ecosystem of Internet of Things (IoT), where every smart object is connected to Internet,...
Smart cities aim to improve the quality of urban services and their energy efficiency by utilizing information and communication technologies. In such context, drones can be utilized to support various services, such as traffic monitoring, search/rescue, and surveillance, by communicating with many different smart objects like sensors. Securing such communications is crucial to making correct decisions...
IEEE 802.11ah is proven to be a suitable communication standard for Smart City projects. However, due to the absence of Restricted Access Window (RAW) size adjustment and proper relay node solution, it fails to optimally utilize the resources in heterogeneous networks. In this paper, we propose a method to estimate the RAW size based on traffic loads and provide Relay node support for stations to...
Smart systems - according to a simplistic definition - provide new qualities and new functionalities through the integration of formerly distinct functions, components and networks. Street-lighting (as other lighting applications) recently went already through a drastic change offered by “LEDification”. The easy electronic controllability of LEDs as light sources triggered a new change of paradigm:...
User interaction is an important part of the smart gridconstruction. In order to allow power consumers to have a better understanding of their own household electricity, it is necessary to provide them with real-time electricity information. On the basis of intensive study of the electricity information acquisition system, this paper puts forward a construction scheme of power information visualization...
The efficient water resource management represents an always more modern and important theme. During last years, debates on water scarcity present on hearth have been quite heated, along with several considerations about the current water supply network inadequacy and obsolescence In fact, timeworn and often bad maintained infrastructures highly contribute to Non-Revenue Water (NWR) increasing. Various...
The Internet of Things is becoming a critical subject nowadays and along with an increasing adoption of ubiquitous computing devices security becomes an issue which must be approached in different application contexts. One notion that gains traction along with the IoT (Internet of Things) paradigm is the social context of embedded devices. This paper proposes a participatory verification security...
Many cities around the globe are adopting the use of Information and Communication Technology (ICT) as part of a strategy to transform into Smart Cities. These will allow cities in the developing world to cope with the ever increasing demand for services such as an effective electricity supply, healthcare and water management. Machine-to-Machine (M2M) communication standards play a vital role in enabling...
A lot of data and data processing functionalities are available in the context of Smart City and Internet of Things and Services. These capabilities are accessible via services and offered via service marketplaces. Marketplaces enable service trading functionalities to their participants. It is observed that the number of service marketplaces is growing. This makes an assessment according to the systems...
Cloud computing has experienced enormous popularity and adoption in many areas, such as research, medical, web, and e-commerce. Providers, like Amazon, Google, Microsoft, and Yahoo have deployed their cloud services for use. Cloud computing pay-as-you-go model, on demand scaling, and low maintenance cost has attracted many users. The widespread adoption of cloud paradigm upshots various challenges...
Smart health care, smart transportation, smart buildings, smart homes, smart water networks and smart electric grids may form the main parts of future smart cities. Standard communication protocols facilitate interconnectivity between software components and assure interoperability between different stakeholders of these components. For electric grids, standards introduce an open Smart Grid for liberalized...
In recent years, vehicular networks has drawn special attention as it has significant potential to play an important role in future smart city to improve the traffic efficiency and guarantee the road safety. Safety in vehicular networks is crucial because that it affects the life of humans. It is essential like that the vital information cannot be modified or deleted by an attacker and must be also...
The Constrained Application Protocol (CoAP) is a promising candidate for future smart city applications that run on resource-constrained devices. However, additional security means are mandatory to cope with the high security requirements of smart city applications. We present a framework to evaluate lightweight intrusion detection techniques for CoAP applications. This framework combines an OMNeT++...
This work presents a wireless sensor platform implemented on a UWB time-coded semi-passive RFID tag. Several sensors are integrated in the tag, connected to its microcontroller either by means of an analog-to-digital converter or using an I2C bus. An EEPROM memory is also connected to the I2C bus to store measurements. The sensor is normally in sleep mode and only wakes up when the reader contacts...
We propose a network management system which is suitable to disaster situation in U-city environment. U-city is a smart city with the intelligent convergence system that integrates IT technology and urban engineering technology such as environment, road traffic, safe and GIS. The network used in U-city should provide services without transmission failure and support functionality which enlarges the...
