As already noted, there is interest in handling in-network processing, even while
the data are being routed. Communications links may be expensive (not only from an
electromagnetic spectrum perspective, but also in terms of the operational support of
the requisite infrastructure); the bandwidth may be limited; and the power availability
at the sensor may be limited and/or expensive in reference to supporting a high capacity/high-range link (i.e., to feed a high-power antenna).
