Abstract
Bluetooth is a promising short-range wireless
communication technology with the characteristics
of interference resilience and power
efficiency, both desirable for wireless sensor
networks. The new Intel Mote sensor devices
have Bluetooth technology incorporated as the
standard wireless communications interface.
When using Bluetooth in applications where
multihop routing is required, groups of Bluetooth
piconets combine together to form a scatternet.
However, most of the existing scatternet
formation protocols are designed to facilitate
communications between any two pairs of
devices, regardless of the actual traffic demand
pattern. For wireless sensor network applications
with low-duty-cycle traffic patterns, an on-demand
scatternet formation protocol can
achieve significant power saving by avoiding
unnecessary network connectivity. To that end,
we introduce an on-demand scatternet and
route formation protocol designed specifically
for Bluetooth-based wireless sensor networks.
Our protocol builds a scatternet on demand,
and is able to cope with multiple sources initiating
traffic simultaneously. In addition, our
energy-aware forwarding nodes selection
scheme is based on local information only, and
results in more uniform network resource utilization
and improved network lifetime. Simulation
results show that our protocol can provide
scatternet formation with reasonable delay and
good load balance, which results in prolonged
network lifetime for Bluetooth-based wireless sensor networks.
