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
+
g
2
) and
O
(
Dg
/
l
+
g
4
), where
l
∈ Θ( max {(1 −
s
),
α
}).
