Energy-efficient vertical handover parameters, classification and solutions over wireless heterogeneous networks: a comprehensive survey

In the last few decades, the popularity of wireless networks has been growing dramatically for both home and business networking. Nowadays, smart mobile devices equipped with various wireless networking interfaces are used to access the Internet, communicate, socialize and handle short or long-term businesses. As these devices rely on their limited batteries, energy-efficiency has become one of the major issues in both academia and industry. Due to terminal mobility, the variety of radio access technologies and the necessity of connecting to the Internet anytime and anywhere, energy-efficient handover process within the wireless heterogeneous networks has sparked remarkable attention in recent years. In this context, this paper first addresses the impact of specific information (local, network-assisted, QoS-related, user preferences, etc.) received remotely or locally on the energy efficiency as well as the impact of vertical handover phases, and methods. It presents energy-centric state-of-the-art vertical handover approaches and their impact on energy efficiency. The paper also discusses the recommendations on possible energy gains at different stages of the vertical handover process

A roadmap for a green interface selection standardization over wireless HetNets

Wireless heterogeneous networks (HetNets) have been widely deployed in parallel with the dramatic increase of smart mobile devices. Nowadays, people use these devices to access the Internet, communicate, socialize and handle their short or long-term businesses. As these devices rely on their batteries, energy-efficiency has become one of the major issues in both academia and industry. Due to terminal mobility, variety of Radio Access Technologies (RATs) and need to be always best connected (ABC) to the Internet anytime and anywhere, energy-efficient interface selection has to be taken into account carefully. In this context, this roadmap intends to raise the awareness of energy efficiency, and to highlight a green interface selection process in which additional standardization is needed. The roadmap first describes essential rules of energy- efficient interface/network selection procedure. Then, it discusses future policies of green interface selection standardization for smart mobile devices, from the perspective of governments, non-governmental organizations (NGOs) and companies
