A nonuniform grid-based coordinated routing design in wireless sensor networks is presented. The conditions leading to network
partition and analysis of energy consumption that prolongs the network lifetime are studied. We focus on implementing routing in
densely populated sensor networks. By maintaining constant values for parameters such as path loss exponent, receiver sensitivity
and transmit power, and varying between uniform and non-uniform grids, we observe energy consumption patterns for each of
the grid structures and infer from the network lifetime the better suited grids for uniformly and randomly deployed sensor nodes.
