Recovery of Sensors in Wireless Sensor Networks

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
The failure in cluster at a high level can bring up great damages to the system in wireless sensor networks where clustering techniques are used. Certain methods have been reported in the literature in recovering the sensors from a failure cluster. One of the most important methods is to recover the sensors in run-time and without clustering. But it is

Wireless Fingerprints Inside a Wireless Sensor Network

ACM Transactions on Sensor Networks, 2015
We discriminate between different SiLabs IEEE 802.15.4 2.4GHz RF sources using the Ettus Labs USRP1 Software-Defined Radio. The wireless fingerprinting method implemented on the USRP1 device exploits differences in the phase attributes of demodulated data samples.
