Abstract:

The sink node deployment problem in wireless sensor networks is studied. By dividing infinite search space into a limited number of so-called "communication intersections", computational complexity has been significantly reduced. A grid-based linear programming is formulated and numerical results show the effectivity of the proposed approach.

Key words: wireless sensor networks, communication intersections, sink node, network lifetime
