PPT-Detecting Phantom Nodes in Wireless Sensor Networks

J Hwang T He Y Kim Presented by Shan Gao Introduction Target the scenarios where attackers announce phantom nodes Phantom node Fake their ranging information Identify and filter out. g shooter detection Goals of clock synchronization Compensate offset between clocks Compensate drift between clocks terms are explained on following slides Time Synchronization Sensing Localization Duty Cycling TDMA Ad Hoc and Sensor Networks Roger W Abstract. Ad hoc low-power wireless networks are an exciting research direction in sensing and pervasive computing. .. . Prior security work in this area has focused primarily on denial of communication at the routing or medium access control levels. . . Outline. Background. Classification of Routing Protocols.

Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies. CS577 . Advanced . Computer Networks . WSN Outline. Introduction. Mote Revolution.
