An extensive area implementation of fully observed greenhouses
motivates on research, especially in remote greenhouses. However,
implementation of wireless sensor networks (WSNs) is still needed for
investigation. Cognitive radio sensor networks (CRSNs) took advantage of using
the cognitive radio (CR) concept to which allowed wireless sensor networks to
dynamically access intowhite
space channelswhich
is unused channels. In this paper, we adopted the Generalized Implicit-OR as
CRSN sensing protocol to reduce the energy consumption and increase the network
lifetime in multiple numbers of greenhouses. Our results showed thatenhanced energy consumption and improved network
lifetime compared to ordinary WSN.
