University: Southern Research: RADAR: A Routing Scheme for Wireless Sensor Networks We are proposing a routing scheme for wireless sensor networks with the goal of improving the network's lifetime under battery constraints, while at the same time offering low computational cost for routing/scheduling. Given one base station and a set of nodes representing heads of sensor clusters in a given snapshot of the sensor field, the scheme (referred to as RADAR for “Radial Routing”) organizes first the nodes into regions along imaginary radii or “chains,” and then finds quickly an optimal energy-efficient routing for all the nodes in each chain (radius). All nodes in each chain are indexed monotonically so that a node with lower index (farther from the base station) can transmit its packet only to a higher-indexed node of the same chain or to the base station. The scheme offers low computational cost, good performance, and high scalability. Teaching: Course: ECE-422: Introduction to Data Communications Networks.
