Wark, Tim, Crossman, Chris , Valencia, Phil , Corke, Peter, Bishop-Hurley, Greg , & Swain, Dave (2008) Poster Abstract : A sensor network for compression and streaming of GPS trajectory data. In SenSys '08 ; Proceedings of the 6th ACM conference on Embedded network sensor systems, ACM, Sheraton Raleigh Hotel, Raleigh, North Carolina, pp. 439-440.
We present the design and deployment results for PosNet - a large-scale, long-duration sensor network that gathers summary position and status information from mobile nodes. The mobile nodes have a fixed-sized memory buffer to which position data is added at a constant rate, and from which data is downloaded at a non-constant rate. We have developed a novel algorithm that performs online summarization of position data within the buffer, where the algorithm naturally accommodates data input and output rate mismatch, and also provides a delay-tolerant approach to data transport. The algorithm has been extensively tested in a large-scale long-duration cattle monitoring and control application.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
