Abstract:

Wireless sensor networks (WSNs) are best characterized by two types of
dominating traffic patterns, namely, one-to-many communication in the
control plane and many-to-one communication in the data plane. Scaling law
analysis provides fundamental understandings to the limitation of various
communication paradigms. In this talk, we summarize our recent results on
the asymptotic behavior of data dissemination and data gathering
operations in WSNs. In particular, we determine the optimality of sink
tree-based relay schemes, the commonly adopted practice in WSNs, in
different attenuation regimes.
