In this project, we will extend and advance the state--of--the--artin the field of sensor network research in two important ways.First, we will design, implement, and distribute a simulation environmentdesigned specifically for sensor networks of hundreds of thousands ofnetwork elements. The basic simulator will be designed from the beginningwith scalability in mind, and will use distributed simulation methodsto increase the available memory and CPU power that and be utilizedto conduct the simulation experiments.Secondly, we will design and demonstrate a set of protocols designedspecifically for data dissemination in a very large--scale sensornetwork environment. These protocols will be power and bandwidth aware,allowing a maximization of data throughput while at the same timeextending the overall life of the network by limiting energy costsat individual network elements. The protocols will be designed tosupport a hierarchical view of the network, and will support primitivesfor data aggregation methods and selective attention of high--prioritymeasurements.Our simulation environment will be freely available to allresearchers working on large--scale wireless networks, and will fosterincreased attention to network performance as the network scales totens or hundreds of thousands of elements.Our power and bandwidth aware protocolswill encourage deployment of inexpensive environmental sensing devicesthat interact in a cooperative manner to insure sensor data is reliablydelivered to the end--user on a timely basis.
