Project Title: Ambient Air Quality Monitoring using Integrated Secure Wireless Sensor and Vehicular Networks Pakistani Principal Investigator: Muhammad Tahir Hafiz Malik Reporting Period: October 1, 2012 September 30, 2013 Summary of Activities During Reporting Period: U.S. Principal Investigator: During the last year, focus of our research was development, testing and evaluation of secure communication and resource optimization algorithms. To date we have developed, tested, and evaluated our algorithms on three types of sensor nodes, (a) commercial sensor nodes such as MicaZ etc., (b) sensor nodes acquired from Dr. Tahir s Lab, and (c) sensor nodes developed at the UM-Dearborn. A brief overview of research activities and tasks accomplished during the last year is provided below. Sensing-enabled data security and verification: we have developed efficient algorithms and a prototype for secure data transfer over a short-range using near field communication (NFC) protocol. More specifically, sensing-centered data security algorithms were developed for NFC is a short-range, standards-based wireless connectivity technology, based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity. o Human gesture activated secure NFC - I: Human gesture recognition method was used for NFC, that is, human gesture is used for triggering NFC service/application. Motion sensor such as an accelerometer is used to record human movement like walking, running, posture transition, etc. A template matching based similarity detection algorithm was implemented to compare the data samples with pre-defined human movement templates. For better accuracy, the 3-D accelerometer and gyroscope sensors were used for 3-D motion human gesture template generation and matching. A prototype was developed using a Google Nexus Smartphone which is equipped with a 3-D accelerometer. To this end, a simple Android application was written to collect the data and tested on Google Nexus smartphone.
o Human gesture activated secure NFC II : In our second algorithm, we used statistical modeling based method to parameterize the human gesture templates. Maximum likelihood estimation based framework is used to estimate underlying density parameters which are used for human gesture motion recognition. A prototype was developed and tested using a Google Nexus Smartphone. To this end, a simple Android application was written to collect the human gesture-motion data, and tested in Matlab environment. The hardware development for solar energy harvesting and data acquisition using vehicular communication: we have designed and tested hardware for solar energy harvesting using sensor nodes. Sensor nodes from Dr. Tahir s Lab in UET Lahore, Pakistan, (our counterpart in Pakistan), commercially available MicaZ, and designed at UM-Dearborn were used for testing solar energy harvesting and data acquisition using vehicular communication. Design and development of hardware for sensor node realization and data visualization: we have developed hardware for rapid gas sensor node realization. The sensor nodes developed, in our Lab at the UM- Dearborn, are capable of monitoring up to five air pollutants. We have also developed a graphical user interface (GUI) visualization of instantaneous as well as long-term air quality data trends. A group of undergraduate students is working on developing algorithms to generate real-time spatial-temporal map for each sensor node in the network. Study of gas sensor nodes from Dr. Tahir s Lab: we have also completed the study of sensor nodes received from Dr. Tahir s Lab. Sensor calibration: During my Pakistan visit last January 26 Feb 2, 2013, me and Dr. Tahir visited SUPARCO Pakistan for gas sensor calibration. I also visited Dr. Tahir s Lab during this visit and acquired four sensor nodes. At UM-Dearborn, are are developing a gas sensor calibration set up to calibrate gas sensor nodes developed at the UM-Dearborn. I also participated in the First Pakistan-US Science & Technology Symposium, where we presented the project progress and gave a real-time demo of our experimental testbed. Pakistan Side: During the last year, our focus has been on the development and deployment of multiple sensor nodes. To date we have developed and tested a batch of sixteen sensor nodes, of which four sensor nodes are being used on the US side for experimentation. A packaging case has been designed and developed for deployment and we are currently working for its further improvement to make it capable of withstanding severe weather conditions. Below is the brief list of tasks that we have accomplished during the last year. 1) The hardware development and testing for a batch of sixteen sensor nodes has been completed.
2) Simple data transfer protocols and graphical user interface for data visualization have been implemented. 3) We are in the process of developing our project website, which will host the details of the developed tools as well as serve as the source of online sensor data obtained from our sensor nodes. 4) The current firmware development activity is concentrated on the data storage and retrieval from local sensor node buffers. We are implementing widely used data structures for efficient information storage and retrieval. Additionally, we are developing some over the air programming capability for parametric configurations of the sensor nodes. 5) A visit to SUPARCO Pakistan was arranged for calibration of our gas sensors and a hardware setup for that purpose is developed. 6) We participated in the First Pakistan-US Science & Technology Symposium, where we presented the project progress and gave a real-time demo of our experimental test-bed.

Two graduate students are working on developing a Test bed for Air Pollution Monitoring using Wireless Sensor Networks. Pakistan Side An undergraduate group of students () is currently working on different aspects of the project. The key project activities accomplished by them as well as currently in progress are (a) the communication protocol implementation for over the air configuration of the sensor nodes allowing us to change parameters of installed sensor nodes wirelessly, (b) implementation of real-time-clock (RTC) functionality and its synchronization for time stamping purpose of the sensed data. In addition, work on the project website is in progress and a second visit to SUPARCO is being arranged to train this group of students the process of gas sensor calibration. An M.S. student Ms. Arfa Dilawari has completed her thesis related to this project. She has developed optimization techniques for improved communication network performance by introducing new dimension to the sensor node design. In particular, she has proposed optimal data flow splitting for sensor nodes with multiple RF interfaces. Her work has resulted in two conference publications in IEEE International Symposium on Personal, Indoor and Mobile Radio Communications and is currently being extended for journal publication. In addition to the above mentioned human resource development, we have used our expertise in the development of an embedded systems laboratory, which is funded by Mentor Graphics Pakistan and grant of Rs. 3.8 Million has been sanctioned. The students will be taught to develop small size embedded platforms and they will learn the development process of software, firmware and hardware and will be exposed to the use of different debugging, programming and testing tools as well. Infrastructure Development: During last year, we acquired four sensor node from Dr. Tahir s Lab and we also have developed 10 gas sensor nodes and two base stations in our lab at the UM-Dearborn. We are working on developing a calibration platform at the in our lab at the UM-Dearborn. We are working on sharing sensor data online.
Pakistan Side: In addition to the infrastructure developed during the previous years, we have developed gas sensor calibration platform. For sensor node packaging purpose we have acquired a cutting machine that can be used for developing different custom casings of different materials. A server is acquired and configured for data hosting and online access of the sensed data. Publications: 1) M. Abbas, M. Tawhid, K. Saleem, H. Mahmood, and H.
