1.2. Contributions
In this paper, we surveyed the variants of WSNs and their potential for the advancement of various agricultural application
development. We highlight the main agricultural and farming applications, and discuss the applicability of WSNs towards
improved performance and productivity. We also classify the network architecture, node architecture, and communication technology standards used in agricultural applications. The real-world wireless sensor nodes and various sensors such as soil, environment, pH, and plant-health are also listed in this paper. In Section 5, we study and review the existing WSN deployments both in the global as well as the Indian scenarios. In summary, the contributions
of this paper are listed as follows.
