medium is inherently broadcast, and there is no clear-cut concept of a communication
link in wireless networks. This gives rise to a fundamental question of whether it still
makes sense to “create” links in a wireless network. Some recent work has made use
of the inherent broadcast nature of the wireless medium to come up with innovative
communication schemes for wireless networks. For example, exploiting the broadcast
nature of the wireless medium can allow transmission schemes that rely on cooperation
between the communication nodes.
These new modalities that the wireless medium offers cannot be accommodated
in layered architectures and, hence, inevitably require some degree of architecture vio-
lation—in other words, cross-layer design. They represent new opportunities for the
cross-layer design effort. Hence, we believe that while proposing cross-layer design pro-
posals to address the issues raised by wireless links, the designers should also keep an eye
out for new opportunities created by wireless communication networks.
8.7 Summary
In this chapter we reviewed the cross-layer design approach in WSN, as well as differ-
ent interpretations of the cross-layer design schemes and their representative cross-layer
design proposals. In addition, we looked at initial ideas on how cross-layer interactions
may be implemented and, as an example, looked at a cross-layer key-distribution scheme
in WSN.
