Today, we see computing outside the realm of personal computers. It has
penetrated into everyday products, enabling useful and interesting applica-
tions. It has been estimated that around 90% of the computing devices are in embedded systems rather than personal computers. The growth rate is more than 10% per annum. According to industry forecast, there will be over 30 billion smart devices worldwide by 2020.
With an explosive growth of smart devices and ubiquitous computing, and a desire to be in a connected society, the Internet of Things (IoT) has become a reality gradually. It is an ever-growing network of computing devices, machines, vehicles, buildings, people, animals and other physical objects with the ability to exchange data over the Internet.
The goal of the IoT is to create smart environments that make energy, transport, agriculture, healthcare, tourism, buildings, homes, cities and many other areas more intelligent. Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) technologies being the critical hardware infrastructure, the IoT system provides remote tracking and monitoring of connected objects and thereby offers numerous applications so as to improve the quality of human life.
While the promises of IoT are exciting, the challenges it offers are manifold. These challenges can be both technical and social in nature and must be overcome in order to ensure its rapid adoption and diffusion. Some of them can be interoperable hardware and software, energy-efficient devices, efficient sensing and identification techniques, communication protocols, quality of service, data analytics and visualization algorithms, security and privacy issues.
Against this backdrop, the paper, “Android-Based City Bus Tracking System”, by Snehal A Demapure and S V Kulkarni, describes an intelligent traffic information system using the notion of IoT. The authors claim that the proposed application is efficient, useful and cost-effective.
The second paper, “Mobile Learning and Evaluation: A New Paradigm of Teaching and Learning”, by Kirti Panwar and Raj Kamal, presents a mobile application that enables a user to learn a subject and test his knowledge while on the move. The system is developed using Microsoft Technologies and claimed to be user-friendly.
The third paper, “E-Sign Detector: Image Steganography-Based Employee Identification System”, by V Senthooran, M T Chathuranga and T Kartheeswaran,
describes a system that identifies and tracks employees in an office who try to enter some restricted area. The authors claim that the proposed system will overcome several problems of manual identification and tracking.
The next paper, “A Comparison of Code Maintainability in Agile Environment”, by Mary Adebola Ajiboye, Matthew Sunday Abolarin and Johnson Adegbenga Ajiboye, presents a research study on time to maintain code in an agile software development environment. It reveals that random pair programmers spend more time per bug on the average, while individual experts spend less time to do so.
The last paper, “The Effect of ERP System on Organizational Performance: A Comparative Study”, by Bharti Motwani and R K Sharma, is an impact study. It reveals that Enterprise Resource Planning (ERP) systems have positive effects on many factors related to organizational process.
