Envisioning Cloud-Inspired Smarter Homes Published: April 10, 2013 • Service Technology Magazine Issue LXXI PDF


The rapid rate of maturity of machine-to-machine (M2M) communication technologies has put their application processes in the spotlight. The initiative of this methodology aims to bring a range of real-time, adaptive applications and services to the forefront.

A number of industry professionals has expressed interest in furthering advancements in this field for a range of business and use cases. People that reside in futurist smart homes, for example, will be able to use smartphones to remotely activate and control home-centric tools for enhanced convenience and comfort. The optimal usage of home appliances and other electronics to reduce energy consumption has become a viable option, while appliance safety and operation can be improved using various forms of higher-performance connectivity.

Another trend of M2M is to enable service providers to collect real-time data from machines and appliances for analysis, before being applied for product design, engineering, and packaging improvement purposes. The key technical components of smart homes, their primary use cases, and the future of home networking, integration, and automation will be discussed and explored in this article.

There are several drivers in M2M technology advancements that are relevant to smart homes, which include the mass production of smartphones, penetration of broadband communications, M2M integration, and adoption of the cloud. Business market research consistently praises M2M for the advantages provided to next-generation services by machines that can remotely and locally connect and collaborate with one another wirelessly. Managed home automation market revenue is predicted to have a compound annual growth rate of 60% until 2017.

Connectivity and Service Paradigms

Connectivity has been assuming a more prominent role in the creation of business innovations. Considerable advancements have been made in the ubiquity, utility, and affordability of the Internet communication infrastructure, as publicly usable content and services are constantly being added to the Web. In parallel, numerous types of electronic devices and distributed systems are also becoming connected to the Web via the cloud.

A recent phenomenon is the digitization of commonplace appliances, with improvisations in edge technologies such as smart sensors, barcodes, and microcontrollers. Ordinary appliances can adopt computational, networking, and perceptive characteristics to join mainstream computing technologies. Another emerging trend is the adoption of the service paradigm so that every IT resource can become expressed as autonomous, discoverable, and composable.

The IT resource capabilities behind service interfaces eliminate dependencies and enable users to find and leverage services at any time. Services are considered to be the most effective option for both legacy system modernization and the development and integration of applications.

The Emergence of the Cloud and Big Data Technologies

Infrastructure optimization is the primary driver behind the cloud, which facilitates the diversified utilization of IT resources and infrastructure to ensure capital and operational cost-savings. Meanwhile, service-oriented software applications are being developed and deployed in cloud platforms to benefit from
cloud characteristics.

A cloud is a virtualized and automated infrastructure that has been centralized to become commonly sharable by multiple customers, which can continuously migrate over software platforms as required. Another critical technology is Big Data, as data is an asset that needs to be aggregated from different sources and stored, processed, and analyzed for the extraction and dissemination of real-world knowledge. The need for Big Data technologies will increase alongside the rise in data volume
and diversity.

Prominent Use Cases for Smart Homes

Use cases are being constructed for futurist homes that provide the self-management of everyday needs by enabling device connectivity, both at home and with the outside world. Activities such as the remote monitoring of the health of the elderly and protection of the home from intruders can be made possible, after these technologies have been implemented to build cognitive applications and services.

At&T has announced plans for a new portfolio consisting of various all-digital and IP-based home security monitoring and automation services. These services, named At&T Digital Life, will provide users with unparalleled control and security over their homes using any Web-enabled device, which can be:

  • cameras, door locks, and appliance power controls
  • smoke, carbon monoxide, and motion sensors
  • thermostats and moisture detectors
  • window and door sensors

Smart Home Monitoring is an advanced home monitoring and automation service that was recently launched by Rogers. From remotely controlling thermostat levels to scheduling lights to turn on at specific times, this system delivers personalized connectivity that can be extended to multiple locations, from the home to the office. This monitoring system enables customers to automate and manage home sensors, thermostats, and small appliances from their tablet or smartphone.

Another example is the Amdocs Connected Home solution, a cloud-based service that enables service providers to rapidly launch pre-packaged home and business services that can be applied to remote security, multimedia, and other areas. These out-of-the-box services considerably reduce the service providers’ development times, as well as investment costs related to inventory control, billing, and customer care.

Smart homes will have their outdoor lighting, climate control, power sources, and alarm system managed via M2M solutions, which will gradually switch to direct radio connectivity for home networking, smart metering, and appliance automation. M2M products and services are currently available in various market segments, which include the transport and logistics, vehicle telematics, smart metering and grid, and healthcare industries.

The Smart Home Architecture

Essential for establishing and sustaining smart homes, home networking, integration, and automation solutions are typically deployed in home integration devices, which have sufficient memory, processing power, and storage capabilities. Every device in the home spontaneously connects via this discovery and mediation middleware to achieve real-time device integration and orchestration towards real-world applications. However, this type of centralized architecture contains the possibility of a single point of failure, since connectivity is centralized at the home server or gateway.

In the smart home era, however, centralized intelligence is distributed between both home servers and the cloud to provide services with cloud scalability and availability. Data that is aggregated and stored in the cloud can provide information on the needs and behavioral patterns of cloud consumers. Several modules that are key to the smart home architecture include:

  • cloud-based service delivery platform (SDP)
  • cloud-based home and device management applications
  • on-premise home integration software solutions, for data and protocol transformation
  • home-bound devices, appliances, sensors, and actuators
  • input /output devices such as smartphones, handhelds, tablets, and personal computers

The cloud-based service delivery platform (SDP) is key for smart homes, as smartphone services that are being deployed to cloud platforms are emerging in parallel with services for home-bound devices. Cloud-based SDPs are the most appropriate for the controlled delivery of these agnostic,
device-specific services.

A new form of cloud middleware solutions that include cloud service brokers or buses (CSBs) are being launched to the market for the locating, binding, and integration of various types of services and data across geographically distributed clouds. Autonomous composite services that are context-sensitive and people-aware can then be dynamically constructed and delivered. CSBs can become the underlying platform for pioneering cloud-based SDPs, whose tasks include automated service loading, configuration, and provisioning.

The device management system (DMS) is another option for the optimal management of home-bound devices. On-demand cloud-based solutions are capable of activating, monitoring, and managing multiple on-premise devices, as well as maintaining the devices’ services and service level agreements (SLAs). Cloud-based multitenant applications can be delivered to numerous devices over any network.

Cloud-based service delivery is rapidly being integrated into a range of industries, and services in security, healthcare, and education have already been increasing consumer convenience and usability. Connected devices have the ability to receive and display cloud content at any time, in any location, as cloud characteristics enable these devices to become smarter in their decision-making, abilities, and performance. The cloud is the critical core infrastructure for domain-neutral application deployment and delivery, and is becoming the central gateway that will be able to host a large variety of services in the upcoming years.


The cloud is recognized as a highly efficient IT infrastructure that has the ability to advance the realization of smart homes. A variety of smart home data, applications, and platforms can be hosted in the cloud to be delivered as accessible and composable services, and the cloud allows tasks like automated service monitoring, governance, management, and usage billing to be efficiently carried out. Conventional homes are set to transform into smart homes by leveraging on the potential that is enabled by the expanding selection of smart technologies and tools.
