摘要

Timing control for delay-constrained data aggregation is critical for improving the performance of a wireless sensor network. In this paper, we propose an adaptive timing control (ATC) mechanism to determine the proper time for data aggregation and forwarding. Given the maximum delay requirements of an application, the ATC mechanism determines the aggregation time for sensor nodes based on both the locations of the nodes and the number of children in the data aggregation tree. The nodes with more children are allocated a longer waiting time. The ATC mechanism maximizes the opportunity for data aggregation and ensures sufficient time to process data from the children. Analytical and simulation results show that the ATC mechanism leads to a higher data delivery rate and lower energy costs compared with existing similar algorithms. Moreover, since a lot of data packets can arrive at the sink earlier, the ATC mechanism is capable of responding more quickly to users.
