PENERAPAN WIRELESS SENSOR NETWORK (WSN) DENGAN TOPOLOGI TREE PADA PEMANTAUAN TANAH LONGSOR

Abstract

Wireless technology (LAN) is a wireless communication technology and current developments are wireless sensor wireless networks (WSN). WSN is a combination of wireless modules, micro module and the sensor module, the way it works is the sensor response value to the micro module and the response values are transmitted through the wireless module. Based on how the WSN can be used for various purposes with one of them for monitoring natural disasters, and in this WSN is designed for monitoring natural disasters landslides.

In general WSN systems have problems such as limited distance limitations. In this system the authors apply the WSN topology tree and spanning tree protocol (STP). Tree topology is a collection of star topology are connected into the bus topology as the backbone lines, while STP is a network communications protocol that has automatic backup paths if the main line is not active.

By applying this system the maximum distance the receiving and sending of data between nodes without the use of the system is 100 meters with 34% packet loss, whereas by applying the system to 100 meters obtained packet loss is 20% and the maximum distance on the overall system is 140 meters with packet loss 30%. With these results we can conclude that the maximum distance is more spacious with menginplementasikan topology tree and adopt the spanning tree protocol.
