| Summary: | Communications-Based Train Control (CBTC) is a modern signaling system that
uses radio communications to transfer information from train control to trains. In
general, the Trackside System network uses conventional Wi-Fi infrastructure
(IEEE 802.11), which means that trains must always do handshaking with an
access point or be connection oriented. This can af ect the performance of the
system because of the limited time each access point has to receive
communications caused by the fast pace of the trains. Therefore, it is necessary to
measure the performance of the system. In this research, a simulation will be
carried out to measure throughput and packet received values to see the
ef ect of interference from adding nodes (devices using wifi) caused by devices
around the CBTC system and the ef ect of train speed on CBTC system
performance. From all the simulations carried out, there are several points of
concern related to the ef ect of increasing the number of nodes on the train on the
ef ect of the performance of the CBTC system. The performance of the CBTC
system is not directly af ected until a certain point where the simulation is carried
out with a total of 35 nodes. Apart from the ef ect of increasing the number of
nodes, a decrease in performance values also resulted in an increase in the
number of train speeds. As the train speed increases, the resulting performance
value will decrease. This is due to the lower window time trains can communicate
with access points. If in the simulation with a speed of 10 m/s, the communication
window time between the train and the access point system is 47 seconds. In the
simulation with a train speed of 50 m/s, the train only has 9 seconds to be able to
communicate with the access point before the access point is outside the range of
the train to communicate. |
