Information and Communication Technology (ICT) has been recognized as one of the main flag ships of global transformation toward a sustainable future, especially because of its capabilities to substitute/virtualize human activities and services. One group of promising ICT approaches to this goal is that of service-based, resource-shared, and virtualized ICT solutions that will be the focus of this project. One of the challenges to be addressed is on how to make ICT a sustainable part of an ICT-dominated world when a marginal role for ICT is not valid in the future.
The NSERC Strategic Network for Smart Applications on Virtual Infrastructures is a five-year partnership between Canadian industry, universities, researchers, research and education (R&E) networks, and high performance computing centres to investigate the design of future application platforms that will deliver software applications of greater capability and intelligence.
Ericsson Ottawa develops cellular base stations that are components of cellular networks marketed by Ericsson. The base stations serve as the interfaces between mobile devices (cell phones) to wired networks and the internet. These network products require high reliability and availability, which results in the need to perform extensive testing on expensive hardware, replicating complex customer network environments. Some tests are expensive, needing to be run for days, while others take seconds.
The Internet of Things is gaining popularity and it will enable the development of new applications that will be useful to businesses in almost any industry and in society. It is expected that more than 50 billion IoT devices will communicate via telecoms networks and will send an enormous amount of data. One major challenge to the successful deployment of this large and heterogeneous network is the problem of capacity planning. An in-depth knowledge of IoT traffic characteristics is necessary to optimize the capital expenditure (CAPEX) but no work has been done so far in this area.
A novel transmitter architecture which presents more power efficiency than that of the transmitters being used currently in mobile communication base stations is proposed in this research project. The result of this research fills the gap between the theoretical idea behind this transmitter structure and its practical usage in cellular network base stations. This transmitter can operate over a wide frequency range and with different mobile communication signal standards very power efficiently while maintaining the quality of the transmitted signal.
For economical and simplification purpose Operators in the Telecom market are looking to move as much as possible of their infrastructure from traditional deployment to Cloud deployment. However Cloud deployment of IMS still need to be defined and developed. This project aims at bringing further the knowledge for such a deployment and helping guide future development for Ericsson. This project focuses on providing future directions for the development of an IP Multimedia System (IMS) in a Cloud environment.
Unlike centralized computing, which is typically performed in a single data-center, Cloud computing enables the computation to be spread across multiple geographically distributed data-centers which are abstracted as a single system by the Cloud management layer. This computational model enables disaster recovery (DR) by re-establishing the services provided by a data-center affected by the disaster in another healthy data-center capable of hosting the applications providing these services.

The mobile traffic has been increased significantly both in volume and in the variety of services in the new generation of broadband mobile networks. This made mobile operators to think about new approaches of data forwarding in wireless cellular networks. With this motivation, mobile operators have started to deploy WiFi to enhance the cellular network capacity. This is done by providing a seamless traffic steering between WiFi and cellular network.
IP multimedia subsystem has been identified by mobile network operators as a promising framework for deploying VoLTE and rich communications services. Offering these services in efficient manner makes it even more attractive. Virtualization represents the suitable concept to achieve this. Moreover, deploying IMS in virtualized environment becomes a solution of great potential especially for multi-tenant application providers. This project aims at defining and validating elasticity management approaches of virtualized IMS based on SLA.
