Abstract

Consider a wireless sensor network with i.i.d. sensors following a homogeneous Poisson distribution in a given area A in R2. A sensor located at x2 ∈ A is directly connected to a sensor located at x1 ∈ A with probability g (x2 - x1), independent of any other distinct pair of sensors. In this letter, we provide a recursive formula for computing Pr (k|x), the probability that a node x ∈ A apart from another node is connected to that node at exactly k hops, for a generic random connection function g : R2 → [0, 1]. The recursive formula is accurate for k = 1, 2 and provides an approximation for Pr (k|x) for k k|x) can be used in a number of areas in sensor networks.
