Goal of pervasive computing is to prompt a thorough inte-gration on information processing into everyday objects andactivities of human beings. With recent advances and maturetechniques in both software and hardware of sensor develop-ment, making a plethora of embedded platforms that equipwell computation, communication, and sensing capabilitiesavailable has brought rich experiences to end users. Thephenomenon indeed reveals dramatic changes on the waywe live, we act, we think, and so forth which all directly arelinked to our daily lives. That is, we have been, or thought tobe, tightly integrated (and linked as well) with these amazingand small things around us. Taking the growing usage ofsmartphone, for instance, you may easily find that modernsmartphones are equipped with a variety of sensors that canbe applied to continuouslymonitor activities (e.g., behaviors),associated geographical information, services, and so on.In addition to those frequently-accessed devices, a rapidly-growing number of sensors (e.g., sensors on/in public facil-ities services or similar devices) around us also makes itpossible to gain understanding of users in the real livingworld of human beings. As a summary of above-mentionedconcerns in this promising area of study, the term “pervasivesensing” identifies, in essence, a promising momentum thatincorporates different techniques, approaches, and thoughtsin a hybrid realm of pervasive computing and ubiquitoussensing so as to overcome individual limitations and achievesynergistic effects.

This special issue received around many submissionsfrom nine countries where the corresponding authors weremajorly counted by the deadline for paper submission. Allthese submissions were considered significant in the area

of pervasive sensing; but, however, only two-thirds of thempassed the first-round examination which is based on a strictand rigorous review policy. After a two-round review process,sixteen papers were accepted for being included in this issue.These accepted papers mainly look at our issue from the per-spectives of smart sensors, wireless sensor networking, sensordata management, data stream processing, RFID, embeddedsystems, distributed processing, artificial intelligence, agenttheory, speech recognition, image and video analysis, signalprocessing, computational intelligence, machine learning,data and text mining, information retrieval, gesture recog-nition, biometrics, text-to-speech processing, software engi-neering, and their union, which lively brought discussions tothe public.

Convergence of intelligent supply chain conditionperception, heterogeneous network access convergence, andresource servicisation are also demonstrated in a real-worldsystem.

A new framework, named energy-awarecentralized heuristic scheme (ECHS), where an energy-awarebenefit algorithm is applied for the determination of activesensor nodes and rotate sensor nodes by periodically recon-structing the scheduling scheme, was first introduced. Fol-lowing the similar consideration, an energy-aware distributedheuristic scheme (EDHS) which serves as the distributedversion of ECHS was presented to provide preliminarysolutions to the real-world problems.

Thegraph theory is applied to represent the nodes (e.g., partic-ipants) and attributes of nodes such as popularity entropyand correlated impacts. A series of algorithms are definedto formulize the applied graph and further discover thisimplicit information among the graphs. With the results, linkprediction is conducted for the comparisonwith other similarworks and brings about the experiences to the real-worldsocial-based applications and services.

A real-world performance evaluation of proposedtechnique outperforms the existing techniques up to 50%in terms of communication and computation overheads andsignificantly reduces the integrity checking and data propa-gation delay.

“Performance evaluation of page migration scheme forNVRAM-basedwireless sensor nodes” byY. Ryu comes back tothe energy issue and tends to solve the low-powered andmul-tifunctional sensor node(s) in an open wireless sensor net-work. A buffer management scheme for hybrid main mem-ory, which combines low-power nonvolatile RAM (NVRAM)and DRAM to reduce the energy consumption in a sensornode, is discussed. The proposed scheme employs the pagemigration technique in order to reduce the write operationson NVRAM part of hybrid main memory. The real-worldexperiment results outperform the legacy buffermanagementschemes in terms of the number of write operations onNVRAM.
