SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Pervasive computing, often synonymously called ubiquitous computing, is an emerging field of research that brings in revolutionary paradigms for computing models in the 21st century. Tremendous developments in such technologies as wireless communications and networking, mobile computing and handheld devices, embedded systems, wearable computers, sensors, RFID tags, smart spaces, middleware, software agents, and the like, have led to the evolution of pervasive computing platforms as natural successor of mobile computing systems. The goal of pervasive computing is to create ambient intelligence where network devices embedded in the environment provide unobtrusive connectivity and services all the time, thus improving human experience and quality of life without explicit awareness of the underlying communications and computing technologies. In this environment, the world around us (e.g., key chains, coffee mugs, computers, appliances, cars, homes, offices, cities, and the human body) is interconnected as pervasive network of intelligent devices that cooperatively and autonomously collect, process and transport information, in order to adapt to the associated context and activity.
The Pervasive and Mobile Computing Journal (PMC) is a professional, peer-reviewed journal that publishes high-quality scientific articles (both theory and practice) covering all aspects of pervasive computing and communications. Topics include, but not limited to:
• Pervasive/Ubiquitous computing and communications architectures and protocols
• Autonomic computing and communications
• Mobile computing systems and services
• Ambient, invisible, implicit, and adaptive computing
• Mobile grid and peer-to-peer computing
• Algorithmic paradigms, models and analysis of pervasive computing systems
• Smart spaces and intelligent environments
• Enabling technologies (e.g., Bluetooth, BANs, PANs, 802.11 wireless LANs)
• Embedded systems and wearable computers
• Wireless sensors networks and RFID technologies
• Virtual immersion communications
• Multiple inter-connected networking technologies (e.g., cellular, ad hoc, hybrid)
• Positioning and tracking technologies
• Auto-configuration and authentication
• Context-aware computing and location-based services and applications
• Service creation, discovery, management, and delivery mechanisms
• Middleware and agent technologies
• Application layer protocols and services
• Programming paradigms for pervasive and ubiquitous computing applications
• User interfaces and interaction models
• Runtime support for intelligent, adaptive agents
• (Innovative) applications requirements, performance, and benchmarking
• Security, privacy, fault-tolerance and resiliency issues.
