In this paper, we address the problem of broadcasting in a wireless sensor network under a novel communication model: the swamping communication model. In this model, nodes communicate only with those nodes at distance greater than s and at most r from them. We consider networks of unknown topology of diameter D, with a lower bound α on the geometric distance between nodes and a parameter g = 1/α (granularity). We present broadcast algorithms for networks of nodes placed on the line and on the plane with respective time complexities O(D/l + g2) and O(Dg/l + g4), where l ∈ Θ(max {(1 - s),α}).
