Abstract. We present Typhoon, a protocol designed to reliably deliver
large objects to all the nodes of a wireless sensor network (WSN). Ty-
phoon uses a combination of spatially-tuned timers, prompt retransmis-
sions, and frequency diversity to reduce contention and promote spatial
re-use. We evaluate the performance benefits these techniques provide
through extensive simulations and experiments in an indoor testbed.
Our results show that Typhoon is able to reduce dissemination time and
energy consumption by up to three times compared to Deluge. These
improvements are most prominent in sparse and lossy networks that
represent real-life WSN deployments.
1 Introduction
One of the main end-user requirements for WSNs is the ability to reprogram the
network after it has been deployed. In turn, the requirement to reprogram the
network generates the need to reliably disseminate large objects (50100 KB)
