Enhancing Clock Skew by Measuring Least Square Fit Method to Identifying Unauthorized Nodes in Wireless Ad-Hoc Networks
Identifying authorized ad-hoc nodes in different networks by monitoring the time difference between the various nodes. The clock skew is defined as the difference in time between simultaneous clock transitions within a system. The measurement of clock skews of ad-hoc nodes in an 802.11 network can be useful to detect the unauthorized nodes in network by use of fingerprints of devices. The fingerprint provides confident to client stations by choosing the authorized and fake nodes in network and wishing to connect to the nodes. Identifying nodes in the wireless ad-hoc network is most important issues to network security.
