Table 1: MoteLab statistics for experimental parameters defined
in Table 2. The statistics for intermediate links, node density,
potential neighbors, and candidate neighbors were collected by
randomly selecting 10 motes from different locations (i.e.,
corner, center) in the test-bed. The statistics for forwarders
and candidates were collected by running BRE on all the motes
(sending a packet every 5 seconds) with a collection root (i.e.,
mote 183), located at one corner of the network.  Experimental
