Introduction to WSN• Distributed autonomous Sensors to monitor

environmental condition• Modern WSNs are bi-directional and can be controlled

by an user from remote location• Physical action can be performed on connected device

through Actuator.• Consists of thousands of Nodes

Introduction to WSN

Sensors• An object whose purpose is to detect events or changes

in its environment, and then provide a corresponding output• A Sensor generally provides electrical or optical signal as

output• Different types of Sensors are:-

• Pressure Sensor• Thermal Sensor• Motion Sensor- Acceleration and Displacement Sensor• Humidity Sensor… etc.

Basic Structure Of Sensor

Tiny OS

Introduction

• It’s an Open source Embedded Operating System• Specially Designed to be used in Wireless Sensor Network• Development started by University of California in co-

operation with Intel Research and Crossbow Technology in 1999• 1st version Ver. 0.6 was released in 2001• Latest Version is Ver. 2.1.2 released in August 2012

OS Architecture• The Kernel of TinyOS is developed in nesC• nesC is a version of C programming language specially customized for

Network and Embedded System Programming• The Front End of the OS is developed in Java and Shell Scripting• The TinyOS is non-blocking and uses only one stack for execution.

OS Architecture

Application Development• Apps are developed using nesC programming.• Programs are built out of the “Software Components”.• Software Components are present in the Hardware Abstraction.• Tiny OS has rich set of predefined functions and core libraries for

manipulation with Sensors

IDEs For Tiny OS App Development• TinyOS Eclipse Plugin “YETI2”- by ETH Zürich• TinyOS Eclipse Editor Plugin- by Rasmus Pedersen, Copenhagen

Business School • TinyDT – TinyOS Plugin for the eclipse platform, Vanderbilt University

Conclusion• In the era od automation, the use of Wireless Sensor Network is

increasing day by day• In India, due to the Smart City project, it’s going to be used in very

wide range

• TinyOS is very useful for WSN as it efficiently manipulates every events in WSN and gives better monitoring.
