A Wireless Sensor Networks is a network formed with sensors that have characteristics to sensor an area to extract a specific metric, depending of the application. We would like to analyse the feasibility to use sensors in a coffee crop. In this work we are evaluating routing protocols using real dimensions and characteristics of a coffee crop. We evaluate, through simulation, AODV, DSDV and AOMDV and two variants known in this work as AODVMOD and AOMDVMOD with 802.15.4 MAC Protocol. For this comparison, we defined three performance metrics: Packet Delivery Ratio (PDR), End -to-End Delay and Average Energy Consumption. Simulation results show that AOMDVMOD overall, outperforms others routing protocols evaluated, showing that is possible to use WSN in a real coffee crop environment.
