Abstract EN
Wireless sensor networks (WSNs) are important parts of Internet of Things or Cyber-Physical Systems (CPS).
WSNs can be seen as a new type of distributed database systems.
The data query processing is very important for WSNs.
In this paper, we proposed a Continuous Top-k Contour Regions Querying algorithm (CTCRQ) which can continuously obtain the top-k contour regions and does not lose the rate of precision (accuracy).
We take full advantage of the kth value of top-k result in current round as the threshold to suppress the nodes whose readings do not belong to the top-k result in next round.
Extensive experiments are conducted to evaluate the performance of the proposed CTCRQ approach by using a synthetic data set.
The results provide a number of insightful observations and show that CTCRQ substantially outperforms Centralized algorithm, Centralized Optimized algorithm, and CCM algorithm in terms of data transmitted.
