Focus of this paper is on energy heterogeneity and distributed algorithms for scheduling and adjustable range.The problem of lifetime enhancement of wireless sensor networks is dealt with the adjustment of transmission or sensing range of the sensor nodes and implementation of heterogeneous energy model.In this work, we deploy the sensor nodes in 2-D using triangular, square, and hexagonal tiles.The initial energies of the sensors and their positions along with the positions of targets are known.For this environment, we investigate the maximu m ach ievable lifetime using heterogeneous determin istic energy efficient protocol with adjustable sensing range (HADEEPS) and heterogeneous load balancing protocol with adjustable sensing range (HALBPS).We observe that deploying the sensors in triangular t iles g ives better lifetime.
