Abstract:
In this thesis, we step inside an unexplored region of Wireless Sensor Networks
(WSNs) research. Nowadays, almost all WSNs research relies upon a hidden
uniformity assumption. This assumption involves deployment, distribution and
radio transmissions. Unfortunately, the real world is not uniform. In the
thesis, we break the uniformity assumption and study the non-uniformity
influence in WSNs. In particular, we show that addressing common WSN problems
taking non-uniformity into account can provide results that are sensibly
different from the ones achieved in a uniform world. In our work, we focus on
the influence of non-uniformity on a particular aspect of WSNs: data
management. First of all, we point out that even widely accepted solutions based
on the uniformity assumption are not able to survive inside an non-uniform
world. Then, we propose our approach to data management and detail a solution
able to deal successfully with non-uniformity. This allows us to catch out the
fundamental aspects of non-uniformity influence in WSNs and to cope with
non-uniformity. Results, discussed in the thesis, show that models and solutions
we propose are competitive in a uniform scenario and continue to work properly
in a non-uniform world.
