Paper Reading #6: An efficient algorithm for scheduling in bluetooth piconets and scatternets

Ramana Reddy, G., Bhatnagar, S., Rakesh, V., and Chaturvedi, V. "An efficient algorithm for scheduling in bluetooth piconets and scatternets". Wireless Networks (10220038). Oct2010, Vol. 16 Issue 7, p1799-1816.

The expressed algorithm sought to get increased throughput and reduced packet delays in bluetooth piconets and scatternets all the while maintaining relatively fair traffic flow.  Using multi-layered parameterized policies, the algorithm schedules on the slave nodes of the network.  The way the group scheduled the packets was based on the two-timescale simultaneous perturbation stochastic approximation (SPSA) algorithm.

The algorithm showed better performance in both piconets and scatternets in polling and data rates for bluetooth over conventional algorithms.  While the performance was greater, I don't think it necessary to necessarily using this algorithm because the performance increase was not astoundingly significant.
