Wireless sensor networks (WSNs) have been
becoming increasingly essential in recent years because of
their ability to manage real-time situational information for
various novel services. Recently, the scope of WSN
technologies has been expanded to places such as the home,
in order to provide the residents with various intelligent
services, such as home automation services or home energy
management services. However, due to their architectural
constraints, such as the trade-off between the performance
and cost, WSNs are not effectively implemented in home
environments. Therefore, this paper proposes a ZigBee-based
intelligent self-adjusting sensor (ZiSAS) in order to address
these concerns. This paper presents a situation-based selfadjusting
scheme, an event-based self-adjusting sensor
network, and hardware and middleware implementation. We
also introduce some smart home services using the proposed
system. We implemented our system in real test bed and
conducted an experiment. Our experiment shows that we
reduce the system’s energy consumption
