Towards providing an over the air reprogramming
functionality for sensor networks, reliable
message communication is the important
requirement. However, this service should be
energy-efficient. Infuse is a multi-hop
dissemination service that uses time division
multiple access (TDMA) based medium access
control. Further, Infuse provides a mechanism for
recovering lost packets in case of unexpected
channel errors. And, finally, Infuse propagates
the code in a pipeline and in an energy-efficient
manner.
