Abstract: The challenges in deploying robust wireless sensor networks (WSNs) in agricultural environments are limited power supply and variability of wireless propagation channel that restrict performance. Proposed protocols do not meet the challenges for realistic simulation and evaluation of WSN for agricultural applications. The design of LEACH protocol is, for the most part, efficient for many applications. It achieves energy efficiency through a clustering technique with TDMA based MAC layer algorithms and data aggregation method. Analysis performed shows that LEACH uses simple radio propagation and energy models that are unrealistic. This paper focuses on the performance analysis of LEACH protocol for agricultural environments.

Keywords: wireless sensor networks; WSNs; low energy adaptive clustering hierarchy; LEACH; vegetation propagation modelling; clustering protocols; MAC layer protocol; medium access control; IoT; internet of things; simulation; agriculture; agricultural applications; energy efficiency; data aggregation.
