초록

Request oriented sensor networks have stricter requirements thanconventional event-driven or periodic report models. Therefore, in this paper wepropose a minimum energy data aggregation (MEDA), which meets the requirementsfor request oriented sensor networks by exploiting a low power real-time scheduler, ondemandtime synchronization, variable response frame structure, and adaptiveretransmission. In addition we introduce a test bed consisting of a number of MEDAprototypes, which support near real-time bidirectional sensor networks. Theexperimental results also demonstrate that the MEDA guarantees deterministicaggregation time, enables minimum energy operation, and provides a reliable dataaggregation service.
