  • Guinard, Dominique; Floerkemeir, Christian; Sarma, Sanjay Emani (Association for Computing Machinery, 2011-06)
    While of increasing importance for the real-time enterprise, deployments of Internet of Things infrastructures such as RFID remain complex and expensive. In this paper, we illustrate these challenges by studying the ...
  • Pardal, Miguel L.; Harrison, Mark; Marques, Jose Alves; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
    Radio Frequency Identification (RFID) technology allows automatic data capture from tagged objects moving in a supply chain. This data can be very useful if it is used to answer traceability queries, however it is distributed ...
  • Ho, Stephen S.; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2009-09)
    Warehouse operations typically aggregate identical stock keeping units (SKU) into the same storage bin for easier bookkeeping and organizing of goods. With the emergence of automatic identification and tracking technologies ...
  • Goyal, Vivek K.; Deshpande, Ajay A.; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers (IEEE), 2010-02)
    We address the optimal sensor arrangement problem, which is the determination of a geometric configuration of sensors such that the mean-squared error (MSE) in the estimation of an unknown trigonometric polynomial is ...
  • Sarma, Sanjay Emani; Mickle, Marlin H.; McFarlane, Duncan; Cole, Peter; Engels, Daniel W. (Institute of Electrical and Electronics Engineers, 2009-01)
    The eight articles in this special section describe state-of-the-art technologies and tools and one application of RFID.
  • Bhattacharyya, Rahul; Floerkemeier, Christian; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2010-09)
    Radio-frequency identification (RFID) has been well established as an effective technology for track and trace applications. In this paper, we go beyond the ID in RFID, and discuss the potential for RFID tags to be used ...
  • Pardal, Miguel L.; Harrison, Mark; Sarma, Sanjay Emani; Marques, Jose Alves (Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
    Service-Oriented Architecture (SOA) and Web Services (WS) offer advanced flexibility and interoperability capabilities. However they imply significant performance overheads that need to be carefully considered. Supply Chain ...
  • Hacker, Patrick A.; Floerkemeier, Christian; Sarma, Sanjay Emani; Schuh, Gunther (Institute of Electrical and Electronics Engineers, 2010-04)
    Previous studies have shown that many consumer goods manufacturers believe that their promotions are not well executed in retail stores. One common concern is that in-store promotions are not synchronized with television ...
  • Floerkemeier, Christian; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2009-01)
    adio-frequency identification (RFID) poses a number of research challenges, such as interference mitigation, throughput optimization and security over the RF channel. A number of new approaches to address these issues have ...
  • Sarma, Sanjay Emani; Floerkemeier, Christian (Institute of Electrical and Electronics Engineers, 2008-12)
    Radio-frequency identification (RFID) poses a number of research challenges, such as interference mitigation, throughput optimization and security over the RF channel. A number of new approaches to address these issues ...
  • Bhattacharyya, Rahul; Floerkemeier, Christian; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2010-04)
    Liquid level detection in customer beverage glasses and liquor bottles in the service industry is important for maintaining quality of service and good approval ratings. Current sensing approaches rely either on visual ...
  • Bhattacharyya, Rahul; Floerkemeier, Christian; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers (IEEE), 2010-04)
    Temperature monitoring is important in a number of fields, particularly cold supply chain applications. Most commercial wireless temperature sensors consist of transceivers, memory and batteries to maintain a temperature ...
  • Bhattacharyya, Rahul; Di Leo, Claudio V.; Floerkemeier, Christian; Sarma, Sanjay Emani; Anand, Lallit (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)
    Ubiquitous temperature monitoring is important to boost visibility in applications such as cold supply chain management. Current sensors monitor and log a time history of temperature data, but their cost limits the scale ...
  • Engels, Daniel W.; Cole, Peter; McFarlane, Duncan; Mickle, Marlin H.; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2009-01)
    The eight articles in this special section describe state-of-the-art technologies and tools and one application of RFID.
  • Kumar, Sumeet; Deshpande, Ajay; Sarma, Sanjay Emani (American Automatic Control Council/IEEE, 2012-06)
    Today's wireless sensor nodes can be easily attached to mobile platforms such as robots, cars and cell phones enabling pervasive sensing of physical fields (say of temperature, vibrations, air quality and chemicals). We ...
  • Ehrenberg, Isaac Mayer; Sarma, Sanjay Emani; Wu, Bae-Ian (American Institute of Physics, 2012-10)
    Demonstrations of focusing with metamaterial lenses have predominantly featured two dimensional structures or stacks of planar elements, both limited by losses which hinder realized gain near the focal region. In this ...
  • Sarma, Sanjay Emani; Floerkemeier, Christian; Bhattacharyya, Rahul (Institute of Electrical and Electronics Engineers, 2009-05)
    The following topics are dealt with: tag circuits; measurement method; simulation method; health care; protocol; sensors; open source RFID software; privacy; security; reader design; antenna; propagation; near-field ...
