ABSTRACT
It is well-known that placing disks in the triangular lattice pat-
tern is optimal for achieving full coverage on a plane. With
the emergence of wireless sensor networks, however, it is now
no longer enough to consider coverage alone when deploy-
ing a wireless sensor network; connectivity must also be con-
sidered. While moderate loss in coverage can be tolerated
by applications of wireless sensor networks, loss in connec-
tivity can be fatal. Moreover, since sensors are subject to
