The deterministic energy efficient protocol for adjustable sensing range (ADEEPS) is one of the important protocols for enhancing the lifetime of a wireless sensor network. This protocol however considers the underlying network of homogeneous nature. In this paper, we propose hetADEEPS (heterogeneous ADEEPS) protocol that considers the underlying network of heterogeneous nature. The heterogeneous network model is parameterized that has 3-level heterogeneity. The proposed model can describe 1-level, 2-level and 3-leel heterogeneity and accordingly the hetADEEPS is referred as hetADEEPS-1, hetADEEPS-2 and hetADEEPS-3. The performance of the hetADEEPS is compared with that of the hetALBP. The hetALBP is Load Balancing Protocol with Adjustable sensing range (ALBP) that has the underlying network of heterogeneous nature. As the level of heterogeneity increases, the network lifetime increases. Furthermore, decreasing the value of the model parameter increases the network lifetime.
