AbstractLandslide is a catastrophic movement of the soil and rock in a downward slope. It is usually an after-effect of earthquakes, heavy rains, volcanic eruptions, or soil erosion. It might lead to injury, death, or damage of property ultimately resulting in financial loss. In order to reduce colossal destruction, it is important to detect landslides before they occur. Typically, a wireless sensor network comprises sensor nodes that are spatially dispersed over an area. The nodes can transmit data with each other wirelessly and also gather data about the variations in physical parameters such as temperature, pressure, etc. Since nodes have restricted or limited resources such as power and sense, they need to be used in an efficient manner in order to improve a network’s lifetime. In this paper, we use the LEACH protocol for clustering and the AODV protocol for routing. NS-2 is a software that predicts the behaviour of computer networks to provide accurate analysis of system performance. The paper aims to evaluate performance through a network simulator for the existing system. The enhanced system shows an improvement in energy efficiency, throughput, packet delivery ratio, overhead and delay through simulation results. Additionally, features like fault tolerance, faster data processing rate, and higher transmission range have been incorporated in the system. In this paper, the enhanced WSN is designed using NS-2 tool for landslide detection.
