Landslides are the movement of slope-forming materials such as rocks, debris materials, soil, or a mixture of these materials, moving down or off slopes. In connection with an early warning of landslides, a very important thing to note is the process of collecting information or data on the occurrence of landslides (landsline). The more points of node sensors are installed on landslide-prone areas, the more accurate the quality of an early warning system is. The research was aimed at creating a model of landslide movement
and creating and analyzing models of multi-sensor data communication based on ZigBee IEEE 802.15.4. The research was to create a model of landslide movement based on the speed rate of soil movement by using a mobile Wireless Sensor Network/WSN and make the laying model of some WSNs (multi nodes) for an area coverage ± 300m2. This modeling used the software of Network Simulator version 2 or NS-2 with a range of scenarios. The results revealed that based on the network quality, the delays of some scenarios were
very erratic; the packet delivery ratio value decreased when the number of clusters and/or nodes increased; and when the number of clusters and/or nodes increased, the throughput got bigger.
