Energy conservation in wireless sensor network using irregular cellular automata

Wireless sensor nodes are severely constrained by energy consumption as they are battery powered. Most topology control techniques that are used for energy conservation assume that the sensor nodes are uniformly deployed, mostly in form of grids. In a real world scenario a grid based deployment presents its own set of problems and limitations. The current paper proposes improvement over a block cellular automata based energy conservation approach. In place of uniform grid, an irregular cellular automata approach has been proposed in this paper. Voronoi tessellations are used for clustering and a new neighborhood rule is proposed for non-uniform neighborhood of irregular cellular automata.
