RF Based Node Location and Mobility Tracking in IoT

摘要

In this paper, a new method RF based IoT node localization and status is proposed. In this paper a robust mapping is done between the measured RSSI vector and the existing RSSI signature to minimize location estimation errors encouraged by the instability problem of RSSI node evaluations. The proposed system extends study on multicast networks in which the communication IoT nodes should be with in the RF server region of the network. In proposed method, the routing is performed peer to peer instead of a static network infrastructure to provide network connectivity. Objectives of this paper are reliable communication, cooperative network, expanding of network and shrinking of network. The study includes RSSI technique for locating the position of the Wi-Fi enabled nodes and determining the variation in the strength of the signal at individual nodes connected to an access point, as the number of nodes increases or decreases.
