Description: Example: Distributed Wireless Control System，可用于无线传感器网络中-This example shows distributed control of a DC-servo using
communication over a wireless network. The example also shows how to
simulate power consumption and how to use the battery block. The model
contains two computer nodes located 20 m apart, each represented by a
TrueTime kernel block. A time-driven sensor/actuator node samples the
process periodically and sends the samples over the network to the
controller node. The control task in this node calculates the control
signal and sends the result back to the sensor/actuator node, where it
is actuated. The wireless communication link is at the same time
subject to a simple power control scheme. Power control tasks running
in both the sensor/actuator node and in the controller node
periodically send out ping messages to the other node to test the
channel transmission. If a reply is received, the channel is assumed
to be good and the transmission power is lowered. If on the other hand
no reply is received, then the transmi Platform: |

Description: To support the varying Quality-of-Service (QoS) requirements of emerging applications such as those involving continuous media, a new standard IEEE 802.11e has been specified [1]. This standard aims to support QoS by providing differentiated classes of service at the medium access control (MAC) layer to enhance the ability of physical layers to deliver time-critical traffic in the presence of traditional data packets. The 802.11e standard defines four access categories (ACs). These four ACs have different transmission priorities. The transmission priority is the probability of successfully earning the chance to transmit when individual ACs are competing to access the wireless channel the higher the transmission priority, the better is the opportunity to transmit.-To support the varying Quality-of-Service (QoS) requirements of emerging applications such as those involving continuous media, a new standard IEEE 802.11e has been specified [1].
