Special issue on energy-efficient wireless communication networks with QoS

Nowadays, we are witnessing a huge increase in the number of mobile subscribers, and also the forecast on the telecommunications market assumes an increase per subscriber’s data rate and the roll out of additional base stations for next generation mobile networks. An undesired consequence is the growth of wireless networks’ energy consumption that will cause an increase of the global carbon dioxide (CO2) emissions, and impose more and more challenging operational costs for operators. This has initiated the need to innovate in the field of energy efficient communications, as wireless network infrastructures as a whole have contributed a significant portion of the total carbon emission of a telecommunication system. As such, wireless networks can play an important role in helping to alleviate the global warming. Various energy efficient networking technologies can be designed to reduce power consumption. However, the effort of saving power and energy must not affect the service quality perceived by a user. It is a major challenge to be able to reduce power consumption and maintain good service quality at the same time. This special issue is devoted to the recent progress on the advanced wireless networking technologies to achieve energy efficiency without compromising quality of service (QoS). We are particularly interested in wireless cellular networks, but innovative and novel works in other types of communication networks are also invited. Original major contributions on the design, analysis, implementation, demonstration, application and standardization of energy efficient wireless networking technologies with QoS will be considered for this special issue. By gathering the relevant cutting edge works, this special issue will identify the unique challenges and the efficient solutions in the area of energy efficient wireless networks with QoS.
