A SURVEY OF ENERGY EFFICIENT APPROACHES OF WIRELESS SENSOR NETWORK FOR PRECISION AGRICULTURE

wireless sensor network, precision agriculture

— The agricultural scenario seems to the
most promising application area for wireless
sensor network (WSN) due to the necessity of
providing the agricultural production chain in
terms of precision and quality. This involves a
careful system design, because requirements are
very strict, such as battery lifetime
maximization, robustness, recovery strategies,
network flexibility and reconfigurable.
The objective of this paper is to review
the various Wireless sensor network technologies
used for precision Agriculture. Wireless sensor
network is used for monitoring the
environmental conditions like soil temperature,
soil moisture, soil fertility, humidity, luminosity
and weed detection. Energy efficiency is one of
the most important design factors for the WSN
as the typical sensor nodes are equipped with
limited power supply. Minimizing energy
consumption and maximizing the lifetime of the
networks are key requirements in the design of
sensor network applications.
