Center node: "query centric cps qcps approach for multiple heterogeneous systems"
  Abstract: In modern scenario we need to have mechanisms which can provide better interaction with physical world by an efficient and more effective communication and computation approach for multiple heterogeneous sensor networks. Previous work provides efficient communication approach between sensor nodes and a query centric approach for multiple collaborative heterogeneous sensor networks. Even there is energy issues involved in wireless sensor network operation. In this paper we have proposed Querycentric Cyber Physical System (QCPS)model to implement query centric user request using Cyber Physical System (CPS). CPS takes both communication and computation in parallel to provide better interaction with physical world. This feature of CPS reduces system cost and makes it more energy efficient. This paper provides an efficient query processing approachfor multiple heterogeneous sensor networks using cyber physical system.This approach results in reduction of communication and computation cost as sensor network communicates using centroid of respective grids which reduces cost of communication whileinvolvement of CPS reduces the computation cost.
