The full coverage of the field is achieved by exploiting the
field division method in uniformly distributing sensor nodes
to guarantee that each division covered by a suitable and equal
number of nodes. The connectivity among sensors is guaranteed
by deploying nodes with separation less than 10 m to mitigate
the effect of foliage on the propagation of radio waves,
while the fault tolerance and reliability are achieved by deploying
redundant nodes in each field division.
