| Abstract | Efficient information delivery in sensor networks is one major research area in the community. In one dimension, efficiency for information delivery in sensor networks includes energy efficiency, capacity efficiency and scalability. In another dimension, the efficiency can be achieved at different network layers: application layer, transport layer or routing layer. These two dimensions describe a design space for efficient information delivery in wireless sensor networks.; We have made several contributions to this design space. First, we have proposed and studied utility-based sensor selection framework to maximize the lifetime of sensor networks at all three layers. Then, we have theoretically studied the problem of energy-efficient broadcasting in a realistic network model. Next, we have proposed and evaluated QCRA, a quasi-static centralized rate control for sensor networks, which achieves capacity efficiency at the transport layer. Finally, we have proposed and evaluated HLR, a data-centric routing protocol that achieves scalability at the routing layer without requiring accurate geographic locations. |
