Sensor Networks for Internet of Things

Over the past two decades, Wireless Sensor Networks (WSNs) and their applications have been the topic of many studies. WSN is a network that collects, processes, and distributes wireless data to the intended database storage center. Applications of wireless sensor networks (WSNs) have been growing at a rapid rate over the past couple of decades.
Also, wireless sensor networks (WSN) will play a fundamental role in the future Internet of Things (IoT), with millions of devices actively exchanging confidential information with one another in a multi-hop manner. IoT is a new emerging technology domain connecting all objects through the Internet for remote sensing and control.
In general, wireless sensor networks represent a new generation of real-time embedded systems with significantly different communication constraints from traditional networked systems.

What is the objective of this course?

Wireless sensor networks (WSNs) offer applications that offer comfortable and smart-economic life. They have become more important in agriculture, landslide detection, production, energy, health monitoring, industrial automation, etc., as networks decrease cost, time, and effort and increase productivity. Wireless sensor networks provide the basis for new computing paradigms that challenge many classical approaches to developing distributed and networking systems. This course mainly covers Bluetooth system architecture, stack and application profiles, RFCOMM, GAP, GATT, SDP, Wi-Fi, network architecture, and WPA firmware.
This course also gives a detailed understanding of GSM architecture, RFID, NFC, GPS, etc.

How do I get a receipt after purchasing a course?

If you purchased a course directly through the platform as a retail user, a receipt for your order will be sent directly to the e-mail address you registered with.

If you received a token to enroll into a course through your organization/college, please contact your college for receipt details. No individual receipts are provided for such purchases

I purchased a course on the platform. How do I start accessing the e-Learning?

You will receive a token number (via e-mail for direct purchase on the platform or through your college/institutions IEEE-BLP program coordinator). Enter the token number on your dashboard on the IEEE BLP platform (after signing in at blended-learning.ieee.org ). You will be successfully enrolled to the course once the platform accepts the token as valid. Click on the Play button for the course on the dashboard to launch the e-Learning program or to perform other activities associated with the course. If you have trouble enrolling for courses, please send an e-mail to support-blp@ieee.org.

I am a faculty at a college and would like to enroll my students for the IEEE Blended Learning Program. How do I do this?

Please contact our sales team at support-blp@ieee.org.

How long do I have access to the courses after successful enrollment (token number accepted by the platform)?

E-Learning access: Three months from the time you enter a valid token number on the platform or until you complete the lab session whichever comes later. The entire program (e-Learning, Lab, and end-of-course assessment) must be completed within 6 months of purchase.

How can I extend access to the e-Learning course beyond the end date?

Please send us an e-mail at support-blp@ieee.org. You may be granted extension upon the sole discretion of the IEEE BLP Program administrator under exceptional circumstances.

I purchased and enrolled into a course but I am not able to continue. Can I get a refund?

Please refer to the course refund policy. You can write us at support-blp@ieee.org

Where can I find instructions to navigate e-Learning?

Navigation Guides:If you have purchased a course from us, you would have received a ‘Getting started version of the Learner Navigation Guide’ from our support team. If you did not, please contact us at support-blp@ieee.org and we will be happy to share one. Help Lecture:If you are having trouble navigating the e-Learning, please click on the ‘Help Lecture’ (represented by a question mark symbol) present on every e-Learning slide.
