5.4 Joint Routing and Information Aggregation
A primary purpose of sensing in a sensor network is to collect and
aggregate information about a phenomenon of interest. While IDSQ
provides us with a method of selecting the optimal order of sen-
sors to obtain maximum incremental information gain, it does not
specifically define how a query is routed through the network or the
information is gathered along the routing path. This section outlines
a number of techniques that exploit the composite objective function
(5.1) to dynamically determine the optimal routing path.
Consider the following two scenarios
