Abstract :
Wireless sensor network is a wireless network that requires low power and
wide range. There are three easy wireless data communication options in terms of
installation and have low power consumption for wireless sensor network
infrastructure, including Bluetooth (802.15.1), WI-Fi (802.11) and Zigbee
(802.15.4). Based on the comparison between Bluetooth, WI-Fi and Zigbee got the
conclusion that Zigbee technology is so superior that the purpose of this research
is to analyze performance and compare Zigbee wireless communication protocol
(IEEE 802.15.4) in three wireless sensor network topologies such as star, cluster
tree, and mesh. The performance measurements of this research use the real device
using Arduino Uno as the microcontroller and also the XBee module as a
transceiver device that supports the Zigbee protocol. Parameters measured include
throughput, packet loss, and delay which is a standard QOS in a network. Based
on the results of the research, the star topology is a topology with a maximum
throughput value of 6.61 Kbps, the smallest packet loss value of 0 %, and minimum
delay value of 35 ms. The superiority of the star topology is influenced by the
network configuration that does not use multi-hop (router) so that data is received
directly by the coordinator. Another problem with using the Zigbee protocol is the
background traffic that causes the quality of the network to increase with the
number of additional nodes.
