Ad Hoc Network Using UAVs in Indian Farms: A Review Shivanta Sahoo, Yash Gupta, Vijay Nath, and Srikanta Pal Abstract Agriculture is repeatedly affected by threats like wild animals, insects, droughts and floods. It is important to safeguard the farmland from various natural disasters and maintains the quality of crops to meet the consumer demand. For this purpose, the Government of India (GOI) has presented a number of rural plans all through the nation to assist the agriculture sector. The farmers need to monitor their crops to ensure the final product is undamaged and well grown. With the help of UAVs, the information related to the farmland could be gathered and sent to the farmer from time to time. But many of the Indian farms are located in deep remote areas with erratic geographical conditions where telecommunications or Internet services are difficult to maintain. So, the motivation of this research is to provide the farmers of our country with proper access to communication and monitoring farmland by using UAVs connected together by an ad hoc network. The ad hoc network will be able to maintain direct line of sight communication with uninterrupted connectivity in hilly areas and mountains. These connected UAVs can scan the crops and act as surveillance from intrusions. Keywords Agriculture · Ad hoc network · Unmanned aerial vehicles (UAV) · Communication technologies S. Sahoo (B ) · Y.
