Bluetooth-Based Smart Sensor Network
                     Bluetooth-Based 
Smart Sensor 
Network
INTRODUCTI
ON
The communications capability of 
devices and continuous 
transparent information routes 
are indispensable components of 
future oriented automation 
concepts. Communication is 
increasing rapidly in industrial 
environment even at field level. 
In any industry the process can 
be realized through sensors and 
can be controlled through 
actuators.

Battery life
When nodes are in a mesh, 
each node has to act as both 
a sensor and a repeater. It 
must constantly listen for, 
relay, and route network 
traffic. Thus, you’ll likely 
experience decreased 
battery life.

Reliability
If one node in a key location 
drops out of your mesh, it 
could take down a good 
chunk of the network.

Cost
Bluetooth is relatively 
inexpensive, but this cost will 
vary drastically depending 
on network coverage in a 
mesh. Covering a small 
home, for example, may not 
be too expensive—but 
covering a large office 
building will be.

Latency
To get a message from point 
A to point B in a mesh 
network, the data will have 
to travel through points C, D, 
E, F, and G first. Thus, to get 
a message where it needs to 
go, you could introduce a few 
seconds of latency.

Isolated 
Sensor 
Networks
An example of an isolated 
sensor network may be a 
small house (where you’re not 
talking extreme ranges). You 
could probably cover the 
furthest reaches with only a 
few nodes—or you may be 
able to cover the area with a 
centrally located access point 
and avoid using nodes at all.

Smart 
Vehicles
Nearly all new vehicles (and 
many older vehicles) are 
Bluetooth-enabled, offering you 
the chance to listen to music on 
your phone or talk through car 
speakers.
 Vehicles offer a perfect 
Bluetooth environment, because 
they are self-contained and all 
devices are close to each other.

Outdoor 
Applications
If you’re considering integrating 
a Bluetooth-based smart sensor 
network at a college campus, 
you might want to think about a 
different sensor technology. 
Not only will the range be 
difficult to tackle, but you’ll be 
trying to work in a congested 
band with interference 
problems.

Dynamic Or 
Mobile 
Networks
If you’re trying to plan a 
Bluetooth network that deals 
with constant movement or a 
dynamic radio frequency (RF) 
environment, you’re in for a 
challenge.
