英语翻译
With ACK,
the transmitter does not send redundant packets for the
information that is already successfully decoded.Hence,the
amount of traffic in the system is reduced and the probability
of collision is smaller at the cost of added complexity
and additional bandwidth to transmit the “ACK”.Another
class of random access based MAC protocols uses carrier
sensing.Basically,a user that wishes to transmit senses
the channel before it attempts to send.Camer sensing
reduces the collisions by avoiding collisions with ongoing
transmissions.The medium access control sub-layer of the
wireless LAN 802.11 standards uses CSMNCA (CarrierSensing Multiple Access/Collision Avoidance).In case of
collision,each transmitter will back off for a random period
of time before its next attempt.In particular,we consider
an exponential back-off algorithm [lo].
In this paper,we study the performance of a networked
control system with a wireless network adopting one of the
MAC protocols discussed above.Given a MAC protocol,
we can find the probability distribution of time delay and
packet losses as a function of p,the probability of success
on each transmission,and the number of time slots in a
sample period.The performance of different MAC protocols
are compared in terms of the control performance index we
choose.
