Abstract

We lay down the foundations of a new approach for finding the network connectivity in wireless networks, with special regard to the properties of dependencies between links of geometrically collocated nodes. The proposed methodology is rooted in the theory of random graphs, but we significantly extend the conventional random graph model, as in its original definition it would be too sterile to capture realistic wireless networks. A closed form expression for the network connectivity was derived by an equilateral hexagon topology introduced from the minimum set covering problem. We also analyzed the effect of boundary nodes on the connectivity of an infinitely and a finitely large network. Through a combination of mathematical proof and simulations, we have shown that our result provides a robust performance in wireless networks.
