Wireless sensor network technology holds great promise for application in agriculture to improve cropyield, improve quality, and reduce costs. This paper presents wireless sensor network coveragemeasurements in a mixed crop farmland. As one of its key contributions, this study shows that generalvegetation attenuation models do not apply to low power wireless sensor networks. A log-linear modelis proposed in this paper and validated for application in mixed crop environment. Unlike in mono-cropenvironment, this study shows that the network coverage is heterogeneous with asymmetric channelbetween communicating node pair. Crop specific parameters of the log-linear model are derived andused to simulate network coverage in a 7 acre test-bed farm. An adaptive energy consumption modelfor each sensor node is proposed and used to compute energy consumption in the network. A clusterhead and two antenna heights deployment model is also proposed and simulated to alleviate shortnetwork lifetime due to vegetation attenuation of signals. The results show that this networkdeployment model extends the lifetime of the network by a factor of more than 20 compare to adeployment where cluster heads are not used.
