Localization game for random geometric graphs

نویسندگان

چکیده

The localization game is a two player combinatorial played on graph G=(V,E). cops choose set of vertices S1⊆V with |S1|=k. robber then chooses vertex v∈V whose location hidden from the cops, but learn distance between current position and in S1. If this information sufficient to locate robber, win immediately; otherwise another S2⊆V |S2|=k, may move neighboring vertex. new distances are presented, if can deduce based all they accumulated thus far, win; otherwise, round begins. has strategy avoid being captured, she wins. number defined be smallest integer k so that game. In paper we determine (up poly-logarithmic factors) random geometric G∈G(n,r) slightly above connectivity threshold.

Localization game on geometric and planar graphs

The main topic of this paper is motivated by a localization problem in cellular networks. Given a graph G we want to localize a walking agent by checking his distance to as few vertices as possible. The model we introduce is based on a pursuit graph game that resembles the famous Cops and Robbers game. It can be considered as a game theoretic variant of the metric dimension of a graph. We provi...

Infinite Random Geometric Graphs

We introduce a new class of countably infinite random geometric graphs, whose vertices V are points in a metric space, and vertices are adjacent independently with probability p ∈ (0, 1) if the metric distance between the vertices is below a given threshold. If V is a countable dense set in R equipped with the metric derived from the L∞-norm, then it is shown that with probability 1 such infini...

Dynamic Random Geometric Graphs

We provide the first analytical results for the connectivity of dynamic random geometric graphs-a model of mobile wireless networks in which vertices move in random (and periodically updated) directions, and an edge exists between two vertices if their Euclidean distance is below a given threshold. We provide precise asymptotic results for the expected length of the connectivity and disconnecti...

Random geometric graphs.

We analyze graphs in which each vertex is assigned random coordinates in a geometric space of arbitrary dimensionality and only edges between adjacent points are present. The critical connectivity is found numerically by examining the size of the largest cluster. We derive an analytical expression for the cluster coefficient, which shows that the graphs are distinctly different from standard ra...

Geometric Inhomogeneous Random Graphs

For the theoretical study of real-world networks, we propose a model of scale-free randomgraphs with underlying geometry that we call geometric inhomogeneous random graphs (GIRGs).GIRGs generalize hyperbolic random graphs, which are a popular model to test algorithms forsocial and technological networks. Our generalization overcomes some limitations of hyperbolicrandom graphs, w...
