Abstract:

With the increasing demand of ubiquitous sensing and cyber-physical
interaction, wireless sensor networks have emerged as one of the key
technologies for many long-term applications such as habitat monitoring,
microclimate study, structural integrity analysis, precise agriculture,
traffic engineering and assisted living. In wireless sensor networks,
energy constraint is by far the most critical hurdle hindering the
practical deployment of this emerging technology. A central challenge is
to sustain the operation of wireless sensor networks for years in
energy-dynamic environments.  Unlike battery-powered systems, which aim to
conserve as much energy as possible, the fundamental objective of
Sustainable Sensor Networks (SSN) is to effectively utilize a continuous
stream of ambient energy. To illustrate our design principle and
methodologies, this talk focuses on energy-synchronized computing -a
holistic approach to synchronize sensor network activities with dynamic
energy supply from the environments.  Specifically, we will discuss a
three-layer architecture for Sustainable Sensor Networks, namely (i) the
design of sustainable TwinStar nodes; (ii) the control of leakage-aware
energy synchronization; and (iii) the adaptation of energy-synchronized
communication and sensing.
