....a location signature from the microwave signals transmitted by the GPS satellites. However, this system is vulnerable if an attacker is able to record the GPS satellite signals and re assemble the aggregate signal with the appropriate delays for the location he is trying to spoof. Gabber and Wool [12, 13] discussed several techniques for tracking the location of set top terminals used for receiving satellite TV. Those techniques include: using the CallerID feature of telephone exchanges; the enhanced 911 location feature of cellular networks; GPS and differentials in the arrival times of the ....

....part of wireless network nodes, it can be deployed in networks today and is expected to become more widely utilized in future systems at reduced expense, size, weight, and power consumption. In addition, the time synchronization signal itself in such systems may be subject to certain attacks [6, 12]. Esoteric hardware such as cesium beam clocks, rubidium clocks, and hydrogen maser clocks, could also be used in special applications today to provide sufficiently accurate time synchronization for months. Although our general requirement for time synchronization is indeed a restriction on the ....

....be known by all nodes in the network. Though this time synchronization can be maintained with off the shelf hardware based on LORAN C [58] WWVB [59] or GPS [ 18, 87] it is currently not a common part of ad hoc network nodes, and the time synchronization signal itself may be subject to attack [23]. Stable time sources such as microcomputer compensated crystal oscillators [8] can provide sub second accuracy for several months. Synchronization to within a few seconds per month can also be achieved using temperature compensated crystal oscillators. Finally, if normal crystal oscillators are ....
