Deployment of IoT based smart environment : key issues and challenges

Abstract

The Internet of Things (IoT) is viewed as a dynamic technological revolution representing future communications and computing in several areas. It introduces physical objects in the sphere of cyber world. IoT is not about a single technology but various complementary technological developments which provides ways to bridge the gap between the real world and the virtual world. A number of wireless sensor technologies are implemented in IoT viz. RFID, ZigBee, actuators, WiFi and wireless sensor networks (WSNs). This paper presents various key technologies involved in IoT and its detailed architecture. IoT architecture explains function of each layer with respect to the technologies and the devices that surround each layer. Each layer has its specific security issues. This paper presents various security threats related to each IoT layer and the specific security requirements. Information security, data protection, and user's privacy are among important key areas in IoT. This paper in the nutshell presents new challenges posed by IoT so that further work can be undertaken in creating a robust, efficient and smart environment for IoT based applications.

IoT Based Human Activity Recognition System Using Smart Sensors

“…Wearable sensors and the advances of wireless networks has opened the door to a world of novel interactive IoT applications. Different types of inexpensive and unobtrusive body-worn sensors like accelerometers, gyroscopes, and microphones have been often used in daily life activities [4]. Various researchers worked on detecting human activities by observing different parameters.…”

Novel Algorithm for Enhancing MANET Protocol in Smart Environment

“…Internet is like a digital fabric that affects our life in one way or others. The internet of people changed the world but there is a new internet emerging which is about connecting things and so its name is the internet of things (IoT), here the things share their experience and communicate with one another [1]. It is like take things and add sense and communication power to them.…”

A Review on Performance Evaluation Criteria and Tools for Lightweight Block Ciphers

“…Furthermore, wireless networks are more prone to attacks than the wired network [2]. A number of attacks can be applied to IoT based applications and to provide sufficient protection against these attacks good cryptographic solutions must be made available to these devices [3,4]. Besides, embedded devices are resource constraint and have limited processing power, low memory available, low energy consumption, and etc.…”
