Please have a look at our 2011 paper on IEEE TSP: We are looking into the Orphaned node problem in a large Sensor Network in the context of Irrigation.
Dear Saman, I'm working on distributed event detection and processing within wireless sensor networks based on pattern recognition approach. I would be interested to work on this area of research. Hope that we could keep in touch. Thanks.
Sorry, though I am not directly working in this area, but would like to join hands in academic project in the filed of artificial intelligence and data science (Have a look at http://www.springer.com/us/book/9783319292052 for newly published book on data science by Springer).
I have completed a few national and international projects and authored 162 publications in last 10 years. My research information is available on my website: http://pritisajja.info/.
