  In wireless ad hoc networks, protecting source and destination nodes location
privacy is a challenging task due to malicious traffic analysis and privacy
attacks. Existing solutions, such as incorporating fake source destination
pairs in the network, provide some privacy of real source and destination nodes
against attackers. Moreover, ad hoc networks need stronger privacy protection
against powerful global attacker which has knowledge of overall network
topology and, that can also eavesdrop and visualize network wide data
transmissions. In this paper, we present a novel privacy technique, (EXTROUT)
Route Extrapolation to camouflage the real source and destination nodes along
an extended path in an ad hoc network. We demonstrate that the privacy level
achieved with EXTROUT is higher and more effective against a global attacker,
when compared to fake source destination nodes privacy scheme.
