Landslide majorly rely on sensor nodes that evaluate geological and geotechnical soilĬharacterization. Monetary losses, economic disruption, and so on, can be minimized. These events cannot be eliminated but the effects like deaths or injuries, Landslides are one of the natural or construction-triggered events that often occur Index Terms: Mobile Ad-Hoc Network, radio transceiver, wireless communication, ZigBee/ IEEE 802.15.4. Considering the performance of ZigBee with its limitations can help researchers to decide the suitable environment, distance between nodes and frame size to establish a wireless ad hoc network for reliable and efficient communication. The experimental analysis of variation in number of obstacles and distance between the nodes that affects the performance of the network in terms of range, network area, packet delivery ratio and latency is presented. This paper presents a study on performance evaluation of low power and low cost-"ZigBee/IEEE 802.15.4" as a wireless radio transceiver in the node design. The simplest form of real world implementation of MANET node can be an embedded circuit with microcontroller, radio transceiver, power source, memory and sensor/s module. Emulation enables repetitive testing of network scenarios with constraints much similar to the real world, but their per node deployment price is greater than simulation. Simulations assume real time scenarios to test the performance which many a times may not result into expected outcomes. simulation, emulation and real world implementation to evaluate the performance of MANET to reduce the impact of these limitations. Researchers have used different techniques viz. But easy deployment without necessity of physical infrastructure makes MANETs a preferred choice for "wireless communication network". Researchers are working on various constraints of MANET, such as limited battery power and bandwidth, lack of central administration and security, need of specialized routing etc. They can be used in rescue/disaster relief operation, forest animal surveillance, military surveillance and data exchange in lecture hall etc. These abilities of MANETs make them useful for the applications where fixed infrastructure is not available or is temporarily down due some calamity. They are portable, compact and battery powered. The nodes can sense, process and communicate wirelessly. : Mobile Ad-Hoc Network (MANET) is a self-structured and self-controlled network.
