Given a set of facilities and a set of users, a reverse nearest neighbors (RNN) query retrieves every user $u$
is said to be influenced by $q$ . In this paper, we propose a relaxed definition of influence where a user $u$ is said to be influenced by not only its closest facility but also every other facility that is almost as close to $u$ returns every user $u$ for which $dist(u,q) \leq x\times NNDist(u)$ denotes the distance between a user $u$ and its nearest facility, i.e., $q$- Published
