For longer period of measurement or data collection energy needs are supported by solar panels and rechargeable batteries if other sources are not nearby which is the case most of the times. Networking of such equipment is based on star, mesh or hybrid topologies. Communication among the nodes are via Wireless Fidelity (WiFi), Bluetooth or Radio Frequency (RF) and they are interconnected to the base centre via GSM/GPRS, RF, Satellites and various other internet infrastructure of the country. Sensors are mostly autonomous which enable us to develop smart agricultural yards or smart natural resources management of livestock, fisheries and forestry
