Topic:
------
Feasibility of Using Bluetooth as a Communications Protocol in Sensor Networks.

Scope:
------
The current generation of sensor nodes rely on commodity components. The choice of the radio is particularly important 
as it impacts not only energy consumption but also software design. Bluetooth is one of the most popular commodity 
radios for wireless devices. As a representative of the frequency hopping spread spectrum radios, it is a natural 
alternative to broadcast radios in the context of sensor networks. The question is whether Bluetooth can be a viable 
alternative in practice. In this project, experiences using Bluetooth for the sensor network regime shall be reported. 
A tiny Bluetooth stack shall be described which would allow TinyOS applications to run on Bluetooth-based sensor nodes, 
a multihop network assembly procedure shall be presented that leverages Bluetooth's device discovery protocol and 
Bluetooth's impact on in-network query processing shall be discussed. This project underlies the limitations and some 
promises of Bluetooth for the sensor netowrk regime.

Major Goals:
------------
1) Understanding Bluetooth and BTNode characteristics
2) Understanding Sensor Networks
3) Suggesting the Tiny Bluetooth Stack
4) Designing a Multihop Network Assembly
5) Using In-Network Query Processing
6) Experiments
7) Results
8) Conclusion
