Abstract
We address the challenges of bursty convergecast in multi-hop
wireless sensor networks, where a large burst of packets from
different locations needs to be transported reliably and in real-
time to a base station. Via experiments on a 49 MICA2 mote
sensor network using a realistic traffic trace, we determine the
primary issues in bursty convergecast, and accordingly design
a protocol, RBC (for Reliable Bursty Convergecast), to address
these issues: To improve channel utilization and to reduce ack-
loss, we design a window-less block acknowledgment scheme
that guarantees continuous packet forwarding and replicates the
