Abstract:

Reliable dissemination of bulk data is one of the important problems in sensor networks. For example, programming or upgrading the software in sensors at run-time requires reliable dissemination of a new program across the network. In this paper, we present Infuse, a reliable data dissemination protocol based on time division multiple access TDMA based medium access layer. Although TDMA guarantees collision-freedom, unexpected channel errors e.g., message corruption, varying signal strengths, etc can cause random message losses. To deal with this problem, we consider two recovery schemes that use implicit acknowledgments. We also present a scheme to reduce the number of message receptions further. With this approach, sensors typically do not receive a given message multiple times. We also demonstrate that our algorithms can handle failure of sensors.
