Smart portable devices have been playing a crucial role inthe long-term evolutionary (LTE) communications and areexpected to be an indispensable part of the 5G system. Whilesmart portable devices (e.g., smartphone and tablets) havepowerful computing and communication capabilities, thehigh data rate services, however, drain out the energy of thedevice much faster than before. For example, a mobile usercan watch a video on a smartphone, to provide an ad for aninteresting item, and tap through the site to purchase it on thephone. However, the current phone battery is not durable tosupport all these activities in one day. Even worse, if a usertypically transmits/shares large volumes of data for a longtime, it will shorten the lifetime of the device significantlyand deplete the batteries rapidly. As a result, cost-effective andenergy-efficient computing and communication mechanismfor smart portable devices are required to be designed anddeveloped.
With the goal of reduction of energy consumption, greencomputing and communication refer to the solutions thatare able to improve the network’s performances in termsof computing/energy efficiency, data privacy, and networksecurity. This special issue intends to bring together theleading researchers and developers from both academia andindustry to discuss and present their views on all the aspectsof green computing and communications for smart portabledevices.
This special issue attracted twenty submissions, and eightpapers are accepted to be published after the peer-reviewprocess with at least three reviewers base on originality,quality, and relevance to this special issue and the journal.The first paper “Greening Software Requirements ChangeManagement Strategy Based on Nash Equilibrium” by Z.Tong et al. looked into the green computing, in softwareengineering, and proposed effective strategies to manage therequirement change based on game theory.
The second paper “Energy Efficient Downlink Transmis-sion inWireless LANs byUsing Low-PowerWake-Up Radio”by S. Tang and S. Obana studied the transmission schedulingin the downlink of a WLAN by using a wake-up radio toremotely activate a WLAN module to receive packets ondemand. The carefully designed scheme reduces the powerconsumption and results in less delay and higher through-put.
The third paper “Multihop Data Delivery Virtualizationfor Green Decentralized IoT” by L. Zhang et al. studiedgreen decentralized communication technologies for IoT andproposed a multihop data delivery virtualization approachwhich uses multiple one-hop reliable transmissions to per-form multihop data transmissions. The real world experi-ments were conducted besides the computer simulations andhigher throughput and shortened transmission time can beobserved.

The fourth paper “A Game Theory Based Approach forPower Efficient Vehicular Ad Hoc Networks” by K. Hua etal. investigated the throughput and transmission delay per-formances for real-time and delay sensitive services througha repeated game theoretic solution towards a power efficientvehicular ad hoc networks.
The fifth paper “Energy Efficiency Analysis of ICNAssisted 5G IoT System” by Di Zhang et al. analyzed theenergy efficiency for ICN assisted 5G IoT system with in-network core router as well as short and long distancescenarios based on the introduced comprehensive systemmodel.
The sixth paper “Energy and Delay Optimization ofHeterogeneousMulticoreWirelessMultimedia SensorNodesby Adaptive Genetic-Simulated Annealing Algorithm” byX. Liu et al. researched an energy-efficient, delay-efficient,hardware, and software optimization platform to minimizethe energy cost, while guaranteeing the deadline of the real-time WMSN tasks.
The seventh paper “Short-Range Cooperation of MobileDevices for Energy-Efficient Vertical Handovers” by X.Foukas et al. introduced the concept of short-range coopera-tion for energy-efficient vertical handovers and developed amodel for capturing the associated mean energy expenditureper handover by means of closed-form expressions.
The eighth paper “Green Data Gathering under DelayDifferentiated Services Constraint for Internet of Things” byM. Huang et al. studied the energy-efficient data gatheringtechniques and proposed a delay differentiated services baseddata routing (DSDR) scheme to improve the delay differen-tiated services constraint that is missed from previous datagathering studies.
