“…However, current algorithms that are based on the fake source technique are of limited relevance, since they make a number of assumptions which limit their practicality. For example, (i) fake sources are often known a priori or arbitrarily chosen [13], (ii) fake sources are selected based on a prohibitively expensive pre-configuration phase or the need to have network-wide knowledge [7], (iii) no common attacker model is adopted, making it is difficult to understand the efficiency of proposed algorithms [7] [13] [10], and (iv) there is a lack of results demonstrating the level of privacy that can be afforded by the fake source technique.…”
