IoT & WSN Center

The IoT-WSN Center provides scope to experiment with varieties of sensor technology devises in the service of mankind – with sensors limited to smartphones to sensors included in an ever-widening variety of places (remote or local sites) and appliances. Experiment with making of ‘smart/connected’ gadgets by networking traditional machinery with added sensors – simulate a state which is referred to as the ‘Internet of Things’, a communicative network that requires no human intervention once set-up to function – possible by consolidating the presence of networked sensors.

The IoT-WSN Center developed at TAT is capable of providing lots of scopes to enable students and researchers to explore different aspects WSN and develop different applications in the field of IoT. IoT-WSN Center provides infrastructural support to make thorough behavioral study and control of WSN nodes and direct access to the WSN gateways to which nodes are connected, allowing students and researchers to monitor nodes energy consumption and other network-related metrics, e.g., end-to-end propagation delay, throughput or overhead, overload conditions, etc. The facility available offers quick experimental setup and deployment, along with easy evaluation, collection and analysis of results. The infrastructure should allow defining complementary test beds with different node types, topologies and environments for coverage of a wide range of real-life use-cases.

The IoT-WSN Center provides ample of scope to the faculties and students to experiment with:

Experimenting with Heterogeneous Platform: IoT-WSN Center provides scope for experimenting with heterogeneous platforms, with different processor architectures (ARM Cortex, ATMega based Arduino UNO R3, Quad Core Broadcom based Raspberry-Pi) and different wireless infrastructures (WiFi, GSM, ZigBee, 2.4 GHz RF, etc.) in the Lab with either fixed or mobile WSN nodes spread across geographically dispersed sites.

Experimenting with Mobility: IoT-WSN Center provides scope to design and develop applications involving mobile entities with either controlled or uncontrolled mobility by integrating some WSN mobile nodes into the entities – they move on the ground in the space that contains the fixed nodes.

Application Development: IoT-WSN Center offers scope for the development of WSN based IoT applications.

IoT-WSN Center has programs in the pipeline to organize training sessions for the students and faculties on the following areas:

• Training on different processor based SBCs, such as ATMega based Arduino UNO R3, Quad Core Broadcom based Raspberry-Pi, Intel Galileo and Edison Boards.
• Setting up of WSNs with Programmable Coordinator & Gateway:
  • Zig Bee Coordinator & Gateway WSN Nodes
  • The coordinators designed around advance processors, such as Arduino UNO R3, Intel Galileo Gen 2, Intel Edision, Waspmote, Beaglebone, Raspberry Pi, etc. and must act as gateway with other wireless connectivity.

Shortly IoT-WSN Center is going announce commencement of a short term training program with a broad outline for the program as follows:

1. Embedded Programming involving Toggling LEDs, transmission of a string through UART, Blinking LEDs through UART, configuring Digital and Analog IO, Toggling LED controlled by Timer, Temperature, humidity, etc. measurement through ADC, etc.
2. Experimenting with RF Communication: Point to point communication of two Arduino UNO R3 Boards over the radio frequency
3. Experimenting with Arduino based WSN Applicatoions: different network topology using Coordinator and end network devices
4. Setting up Single Hop WSN and Multi Hop(Hierarchical) WSN
5. The hierarchical WSN will be configured into three layers, comprising of:
   1. Sink or Gateway Node
   2. Cluster or Coordinator or Router Nodes and
   3. Leaf or End Nodes

Each leaf node will be experimented by interfacing varieties of sensors, like Accelerometer Sensor, Magnetometer Sensor, Light Sensor, Acoustic Sensor, Sound Sensor, Humidity Sensor, Vibration Sensor, Displacement Censor, GPS Sensor, PH Sensor, Soil Moisture, Smoke Sensor, Motion Sensor, Temperature Sensor, Current Sensor, ColourSensor, IR Sensor, Barometric Sensor, Luxometric Sensors, etc.

Simple configuration of an experimental Hierarchical WSN is shows below:

6. Experimenting withpeer to peer network topology using Coordinator and end device network devices
7. Experimenting withpeer to peer communication between Coordinator and end device through a Router
8. Experimenting with Star Network Topology i.e., Many to one Communication
9. Experimenting withTree Network Topology
10. Experimenting withCluster Tree Network
11. Experimenting withIoT applications

Lab facilities at the IoT-WSN Center are open to all the B.Tech. andM.Tech. students, irrespective of their branch of study, to carry out their end-semester projects as per the curriculum, as well as offers program to enrich their knowledge through different beyond-curriculum program modules.

Apart from building conceptual foundation, IoT-WSN Center also extends supports to the students and faculty members to conduct experimental study and write papers based on their experimental findings.

Coordinators of the IoT-WSN Center have initiatives to organize seminars and workshops for the students and faculties on the upcoming areas of technology.
