Call for Papers A Special Issue of Journal of Network and Computer Applications on “Green Network Protocols and Algorithms” The Past decade has witnessed a fast growth in wireless networks that provide connectivity and information to the end users. Along with this network expansion, the necessity of sufficient bandwidth and efficient quality of service is increasingly demanded. Network expansion greedily contributes a large factor of energy consumption and resulted in high environment footprint. It is recently been reported that Information and Communication technology (ICT) sector is responsible for producing 2 % to 3 % of total emission of greenhouse gases. Moreover, according to the GreenTouch initiative, the estimated CO2 emissions from mobile, wire-line and LAN communications is about 25 % to 31 % of total ICT’s global CO2 emission. Thus, it is increasingly necessary to alleviate energy consumption as it is not only becoming scarce and expensive but also causing a dramatic climate change. Green protocols and algorithms are required to reinvent scalable and sustainable network by maximizing energy efficiency and reduce total cost of ownership. Alleviating the energy consumption of network and communication infrastructure by developing power-efficient techniques is a pressing need for researchers in academia and industry. This special issue aims to theme innovative research achievements in the field of green communication and networking. We are seeking original and unpublished papers. Specific topics include, but are not limited to: • Energy-efficient packet forwarding protocol for wireless networks • Energy-efficient geographical routing protocol for wireless networks • Energy-efficient vertical handover for heterogeneous wireless networks • Green radio network architecture design • Green mobile networks protocols and algorithms • Green medium access protocols and channel assignments • Test-beds, case studies, experimental systems and evaluations • Energy-efficiency in tactical wireless networks • Cross layer protocols to optimize energy efficiency • Green routing protocols for vehicular ad hoc networks • Energy-efficient protocols for wireless sensor networks • Energy-efficient protocols for vehicular networks • Energy-efficient secure networking • OpenFlow networks • Software defined networks • Energy-efficient networking protocols • Energy efficient device-to-device, small and dense networks protocols and algorithms • Cellular offloading, load balancing and systems convergence • Cellular energy footprints Important dates Paper submission: 30 September, 2014 Acceptance notification: 15 December, 2014 Final papers: 7 April, 2015 Submission Format and Guideline All submitted papers must be clearly written in excellent English and contain only original work, which has not been published by or is currently under review for any other journal or conference.
