Title: "A survey on wireless sensor and actuator networks"

Miss Dian ZHANG


Abstract:

Although wireless sensor and actuator networks (WSAN) and
wireless sensor networks(WSN) are similar to some extent, WSANs have many
unique features, making them more challenge and need further development.
WSANs usually consist of a group of sensors and actuators. The sensors are
in charge of gathering information about the physical world as they act in
WSNs, while actuators take decisions and then perform appropriate actions
upon the environment. In other word, WSNs are just passive reflection to
the real world while WSANs can be interactive. The most important issues
in WSANs are the sensor-to-actuator and actuator-to-actuator communication
and coordination. In order to provide effective sensing and acting,
coordination mechanisms are required among sensors and actuators. In this
chapter, first we will list the unique features and communication
requirement for WSANs, and make a comparative study of the protocols for
WSANs. Some research problems and challenges are also pointed out in our
future work.
