"PERFORMANCE EVALUATION OF SCHEDULING ALGORITHMS ON BLUETOOTH PICONET AND
SCATTERNET NETWORK"

By

Mr. Kin-Pong Cheung


Abstract

Bluetooth is an emerging communication technology that started as a simple
cable replacement solution, but has quickly advanced to a promising
solution for short range ad hoc networking. Compared to other wireless LAN
technologies, Bluetooth has a number of distinctive features that
significantly affect the performance of Bluetooth networks. However, there
are still very few performance analyses of Bluetooth networks.

In this thesis, we first simulate the queuing delay of a single Bluetooth
piconet traffic under the assumptions that (1) each piconet member
uniformly communicates with all other members, and (2) each member
receives data packets according to Poisson distribution. We also compare
the 1-limited service, k-limited service, exhaustive service Fair
Exhaustive Polling and skip-1 service scheduling with different traffic
models such as exponential ON/OFF and bursty traffic. Simulation results
show that exhaustive service offers better overall performance. We also
consider scatternets that consist of two piconets linked through
Master/Slave and Slave/Slave bridges respectively. In order to compare
performance of both types of bridges, we have simulated the access delay
and end-to-end delay for both local and non-local traffic, assuming that
the traffic is bursty. We find that Slave/Slave bridge offers better
overall performance.
