• [IoT-J'19] Improving IoT data quality in mobile crowd sensing: A cross validation approach [DOI: 10.1109/JIOT.2019.2904704]
  T. Luo, J. Huang, S. S. Kanhere, J. Zhang, and S. K. Das
  IEEE Internet of Things Journal (IoT-J), vol. 6, no. 3, pp. 5651-5664, June 2019.
  
  We propose a cross validation (CV) approach that seeks a validating crowd to ratify the quality of sensor data contributed by the a contributing crowd. Using a weighted ramdom oversampling (WRoS) technique and a PATOP² algorithm which makes an exploration-exploitation tradeoff, the CV approach offers a unified solution to two disparate (and important) needs: reinforce obscure truth and discover hidden truth. (See illustration.)
• [ICC'18] Distributed anomaly detection using autoencoder neural networks in WSN for IoT [DOI: 10.1109/ICC.2018.8422402]
  T. Luo and S. Nagarajan
  IEEE International Conference on Communications (ICC), May 2018.
  
  This paper is the first that introduces autoencoder neural networks (ANN), a deep learning model, into wireless sensor networks (WSN) for distributed anomaly detection. It contradicts the general belief that deep learning is not suitable for WSN, by (1) making deep learning extremely shallow and (2) dividing and allocating computation load to sensors and the IoT cloud with a two-part algorithm. (See illustration.)
• [ComMag'17] Sustainable incentives for mobile crowdsensing: Auctions, lotteries, and trust and reputation systems [DOI: 10.1109/MCOM.2017.1600746CM]
  T. Luo, S. S. Kanhere, J. Huang, S. K. Das, and F. Wu
  IEEE Communications Magazine, vol. 55, no. 3, pp. 68-74, March 2017.
  
  This survey paper provides a technical overview and analysis of six incentive mechanism design frameworks: auction, lottery, trust and reputation system, bargaining game, contract theory, and market-driven mechanism.
• [TIST'16] Incentive mechanism design for crowdsourcing: an all-pay auction approach [pdf] [DOI: 10.1145/2837029]
  T. Luo, S. K. Das, H-P. Tan, and L. Xia
  ACM Transactions on Intelligent Systems and Technology (TIST), vol. 7, no. 3, pp. 35:1-26, February 2016.
  
  The most adopted auctions in incentive mechanism design so far have been winner-pay auctions (WPA), in which only winners (who outbid others and will therefore receive reward) need to pay their bids. By contrast, all-pay auctions (APA) require all the participants regardless of who win the auction to pay their bids. This apparently sounds unreasonable, but when applied to crowdsourcing, it makes perfect sense and gains two important advantages over WPA. (This paper builds on our INFOCOM'14 paper.)
• [TMC'16] Incentive mechanism design for heterogeneous crowdsourcing using all-pay contests [DOI: 10.1109/TMC.2015.2485978]
  T. Luo, S. S. Kanhere, S. K. Das, and H-P. Tan
  IEEE Transactions on Mobile Computing (TMC), vol. 15, no. 9, pp. 2234-2246, September 2016.
  
  Despite that crowdworkers are typically heterogeneous (in abilities, costs, etc.), the daunting challenge of modeling and analyzing such scenarios has restricted researchers to choosing homogeneous models in which all the worker types follow a single, common distribution (Bayesian belief). This paper addresses this challenge using an asymmetric all-pay auction model with a prize tuple. Not only does it achieve better performance, but it also uncovers a counter-intuitive and interesting property called strategy autonomy, in which the asymmetric equilibrium collapses into a symmetric one.
• [TMC'16] Competition-based participant recruitment for delay-sensitive crowdsourcing applications in D2D networks [DOI: 10.1109/TMC.2016.2524590]
  Y. Han, T. Luo, D. Li, and H. Wu
  IEEE Transactions on Mobile Computing (TMC), vol. 15, no. 12, pp. 2987-2999, December 2016.
  
  We tackle the challenge of large delay incurred in Device-to-Device (D2D) networks, by designing two distributed approaches that closely approximate a centralized, dynamic programming algorithm. One is a divide-and-conquer method with Voronoi cells, and the other is a task splitting and delegation scheme.
• [INFOCOM'15] Crowdsourcing with Tullock contests: A new perspective [DOI: 10.1109/INFOCOM.2015.7218641]
  T. Luo, S. S. Kanhere, H-P. Tan, F. Wu, and H. Wu
  The 34th IEEE International Conference on Computer Communications (INFOCOM), April 2015, pp. 2515-2523.
  Acceptance rate: 19% (316 out of 1640)
  
  What is a Tullock contest? Think it as a lucky draw! While auctions have dominated the realm of mechanism design for decades, this paper suggests Tullock contests as a better alternative, on the basis that it is less competitive and more conducive to larger participation.
• [TMC'15] Quality of contributed service and market equilibrium for participatory sensing [DOI: 10.1109/TMC.2014.2330302]
  C-K. Tham and T. Luo
  IEEE Transactions on Mobile Computing (TMC), vol. 14, no. 4, pp. 829-842, April 2015.
  
  Characterizing QoS for crowdsensing is a challenge, and this work proposes a new metric called Quality of Contributed Service (QCS) to aggregate individual quality of contributions by taking information quality and time sensitivity into account. We analyze this metric using a market-based supply-and-demand model.
• [INFOCOM'14] Profit-maximizing incentive for participatory sensing [DOI: 10.1109/INFOCOM.2014.6847932] [Much enhanced version: ACM TIST'16]
  T. Luo, H-P. Tan, and L. Xia
  The 33rd IEEE International Conference on Computer Communications (INFOCOM), April 2014, pp. 127-135.
  Acceptance rate: 19% (319 out of 1650)
  
  All-pay auction + adaptive prize/reward (see the short abstract of TIST'16 or an illustration).

Systems

Besides theory, I am also passionate about developing real systems. I led a team to have developed the following mobile crowdsourcing / crowdsensing applications and made them freely downloadable at Apple Store and Google Play between 2014-2019.
