Our Applications DO require:
 Very
Low Power Consumption
– Disposable wireless sensors
– Should last at least five years for automotive applications and
from a few months to 10 years in Industrial applications
 Low
Cost
– Automotive applications
 Robustness
to handle industrial/vehicular
environments
– Temperature, vibration, humidity, etc

Application Description
Application Question
1
How many devices are there in the
proposed network?
256 sensors/network max.
What are the types of devices in that
2
application?
Stick-On Sensors
Control & Actuators
Wireless Hub
3 Describe how the network is initiated.
Self-configuring upon deployment
How do devices attach and detach from
4 the network? Is human intervention
required?
5 Describe the traffic flow of the data.
Describe the type of data that flows in
6
each branch of the network.
How much data is typically in each
7
message?
8 How often are messages sent?
Submission
Response
Self-discovery. No human intervention
Both Unidirectional and bidirectional
Asynchronous data packets
Adjustable packet length
4 to 10 bytes typical
64 bytes max.
Adjustable. From one a second to once

Application Description
Application Question
Response
How much latency in the message
9
transfer is acceptable?
< 10 min
Piconets/Scatternets
Point-Point/Multihop
Both, Master/Slave & Peer to Peer
with or without Multihop
Devices do not have to support all options
10 Describe the network topology.
Is there a master node? Where do data
11 flows originate and terminate? Are the
devices peer to peer or master/slave?
Does this network have to interface to
12 another network? If so, how should these No
two networks be connected?
If two low-rate networks are in the range
13 of one another, should they interact? If
yes, how?
What is the type of data that would flow
14 between two low rate networks? How
often would they communicate?
How should these two low rate networks
connect when they are within range?
15 Should they configure themselves into
one network or only communicate
between master, for example?
Do the devices support authentication
16
and security?
Submission
Yes, using service discovery
Data
Exchange of status and/or control
information
Service discovery
