Center node: "quality adaptive online double auction in participatory sensing"
  Abstract: Agents (specially humans) with smart devices are stemming with astounding rapidity and that may play a big role in information and communication technology apart from being used only as a mere calling devices. Inculcating the power of smart devices carried by the agents in several different applications is commonly termed as participatory sensing (PS). In this paper, for the first time a truthful quality adaptive participatory sensing is presented in an online double auction environment. The proposed algorithm is simulated with a benchmark mechanism that adapts the existing McAfee's Double Auction (MDA) directly in the online environment.

Connected through hyperedge HE-1 (induced by source paper "online participatory sensing in double auction environment with location information"):
  with members:
    - "incentive mechanisms for participatory sensing survey and research challenges"
    - "participatory privacy enabling privacy in participatory sensing"
    - "models for truthful online double auctions"
