Resumo

This paper studies pure probabilistic broadcast in ad hoc networks under a variety of topological scenarios, offering a comparison of the performance of broadcast in lattice-like geometric node layouts (e.g. nodes arranged in triangular, square and hexagonal grids) with that in randomly placed nodes. Results suggest that the geometry of the position of nodes has an impact on the success of probabilistic broad-cast techniques. Specifically, networks with randomly-placed nodes exhibit a near-ideal (collision-free) behavior, whereas the grid layouts are extremely sensitive to the impact of collisions and interference. To account for the unreliable behavior of broadcast under certain node-distribution geometries, this paper provides an analysis of Signal to Interference ratio for ad hoc networks.
