Concept and approach

The amount of traffic over mobile networks has been increasing exponentially, namely due to the ever-increasing number of mobile services and applications running on top. In the next years with the impact of the Internet of Things (IoT), the number of network-connected devices and corresponding traffic will increase, making it impossible for current mobile networks to provide enough capacity to support this growth. It is therefore necessary to adapt existing wireless technologies to future needs. In particular, the reduction of the energy consumption and ultra-high bandwidth are fundamental features for next generation networks.

The Wi-Green project has the goal of developing new solutions that enable the reduction of the energy consumption of Wi-Fi access points (APs), namely in indoor environments, taking into account the Wi-Fi offloading approach followed in the SooGreen overall solution. The main innovation of the Wi-Green project lies on the optimization of the energy consumption from the point of view of the component that has been forgotten in Wi-Fi networks – the access points. The Wi-Green approach includes the use and adaption of existing mechanisms for analyzing and detecting input and output traffic within an access point, in order to enable the dynamic and traffic-aware configuration of the operation of one AP (BSS – Basic Service Set) or of a network of APs (ESS – Extended Basic Service Set), without compromising performance.

 

Concept and approach

WI-GREEN is integrated with SooGREEN (https://soogreen.cms.orange-labs.fr/soogreen), a project associated to the European cluster Celtic-Plus/Eureka, composed by 16 consortium partners led by Orange France, the project has started in 2015 and have an expected duration of 36 months. SooGREEN intends to explore different solutions to optimize the energy consumption of services/networks in communications, arises from the need to reducing the energy consumption taking into account the constant traffic evolution and for explore new network architectures, keeping in mind the development of smart networks and potentiating areas such as, Internet of Things (IoT) and Smart Grids.
