In this work we present a new routing protocol for sensor networks that utilizes smart antennas to propagate information about a sensed event towards a receiving center. Our protoc...
We study the problem of data propagation in sensor networks, comprised of a large number of very small and low-cost nodes, capable of sensing, communicating and computing. The dis...
