Wireless sensor network (WSN) applications such as
patients’ health monitoring in hospitals, location-aware
ambient intelligence, industrial monitoring /maintenance
or homeland security require the support of mobile nodes
or node groups. In many of these applications, the lack of
network connectivity is not admissible or should at least be
time bounded, i.e. mobile nodes cannot be disconnected
from the rest of the WSN for an undefined period of time.
In this context, we aim at reliable and real-time mobility
support in WSNs, for which appropriate handoff and rerouting
decisions are mandatory. This paper1 drafts a
mechanism and correspondent heuristics for taking
reliable handoff decisions in WSNs. Fuzzy logic is used to
incorporate the inherent imprecision and uncertainty of
the physical quantities at stake
