Non-uniform grid-based routing in sensor networks

A non-uniform 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 implement routing in heavily 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.
