A real time system for intrusion detection and tracking based on wireless
sensor network technology is designed by using the IITH mote which is de-
veloped and designed in IIT Hyderabad as the communication module in the
network.This paper describes the Device-Free Passive Localization system
based on RSSI.The main objective of this paper is to design a DFP Local-
ization system that is easily redeployable, recon�gurable, easy to use, and
operates in real time.
In addition the detection of humans is to be done.The em-
bedded intrusion detection algorithm is designed so that it is able to cope
with the limited resources, in terms of computational power and available
memory space, of the microcontroller unit (MCU) found in the nodes. and
various challenges and problem faced during the real test bed deployment and
also proposed solutions to overcome them.We presented an alternative algo-
rithm based on the minimum Euclidean distance classi�er.our result shows
that the localization accuracy of this system is increased when using the
proposed algorith
