Course Descriptions: This is an upper-undergradaute and first graduate-level course in computer networks for students in information systems. This course will introduce students to the key concepts of underlying wired, and wireless networking. The layered architecture of the network protocol stack will be the focus of discussion. Alongside, a variety of case studies will be drawn from the Internet, combined with practical programming exercises. At the end of the semester, students will well understand several concepts, including the Internet architecture, HTTP, DNS, P2P, Sockets, TCP/IP, Routing protocols, IEEE 802.11, wireless and sensor networking, mobile computing, cellular and satellite networks, security, etc.

Course Objectives: This course aims at introducing the students to modern computer networks, in particular the Internet. We will discuss basic network architecture, design principles, different protocols, and applications. We will study the application, transport, networking, and link layers.

Hands-on Data Communications Research and Development Project (Sponsored by Constellation Energy):
In general in an upper undergraduate and lower graduate level computer networking course we discuss fundamentals of networking and communications in theory but most often we do not get the opportunity to test it on real everyday devices. Sometime we do simulation study to fulfill that requirement. In this course we will have an important component as part of our learning curve to deploy, test, compare, and if needed to make changes to the communication protocols to have access to real data on real devices commercially available in the market. In this semester, we will specifically focus on exploring devices for green building energy management such as smart plugs for fine-grained energy metering in home environment. For example, iMeter Solo, Z-Wave Smart Energy Power Strip, Enmetric Systems; all are smart plugs which are used for measuring power consumption of different appliances in an intelligent building environment. Believe it or not these devices advocate different types of communication protocols such as Wi-Fi (IEEE 802.11.x), ZigBee (IEEE 802.15.4), Bluetooth, X10, ANT, or Bluetooth low energy (BLE), Power Line Communication (PLC) etc., based on an application specific requirements and device hardware-software compatibility.

The idea of this project is to set up those real devices in your own living environment and find out what communication protocol has been employed to transport the DATA and how useful it is for that specific application? Is there a better alternative? At the end of this study we would like to hear from each group of students about your recommendation for a specific device, the technology it has used, how it has been deployed to communicate data? A comparative study on different communication protocols we use in our day to day lives, either knowingly or unknowingly based on different metrics such as range, power consumption, RSSI signal strength, security etc., would be well appreciated by the peers and albeit by the instructor!

All the devices will be provided by the Mobile, Pervasive and Sensor Computing (MPSC) Lab in the Information Systems department at UMBC. We heartily acknowledge our sponsors Constellation Energy to make this student hands-on data communications and networking project possible in Fall 2015.

The project is motivated by our effort on developing non-intrusive, energy-efficient, cost-effective scalable technological solutions for green building and independent living applications.  Please see the following Wall Street Journal article on sensor enabled technologies for independent living. Please recall that it is not possible to scale this system if the underlying communication protocols are not robust, energy-efficient, secure, fault-tolerant and universally acceptable with their coexistence in a variety of different hardware or software domains.

Logistics, Requirements & Deliverables:
1. Form a group of 3 students at the undergraduate-level and 2 students at the graduate-level.

2. Decide by the last week of September what devices you want for your project. Keep in mind that our goal is to find out which device should be an ideal choice for large scale smart home and green building energy management applications. So keep an eye on the cost of the device along with its hardware and software versatility to make a win-win recommendation.

3. You are expected to give a demo of how your system works, what underlying communication protocol has been deployed and why?

4. Submit a 3-page report (undergrads team) and a 6-page report (grads team) to the instructor by email. More details will be provided later.
