资源说明：Abstract—For the application of wireless sensor network
technology in an energy self-sufficient condition monitoring
appliance, we propose a new hybrid network topology to combine
the advantages of the ZigBee standard with the need for lowest
power consumption when applying an energy harvesting solution
for a subset of the sensor nodes.
For a research project on a wireless condition monitoring
system, we developed a prototype implementation of a partly
energy self-sufficient wireless sensor network. We adapted the
ZigBee network protocols so that the energy consumption of
the self-sufficient nodes is reduced albeit a ZigBee conform
communication with the rest of the network is still ensured. In
this paper, the prototype system is presented and the problem
when applying a full ZigBee stack is stated. We propose to shift
parts of the network functionality from the end-devices to the
(mains- or battery powered) routers and show actual measurement
results and calculated values to indicate the improvements
of this adapted hybrid topology.
