Efficiency Parameter (Latency) for Wireless Network to Increase QOS
نویسندگان
چکیده
Bluetooth is a personal wireless communication technology [2] and is being applied in many scenarios. Current existing scheduling scheme only provide best-effort service for all master-slave connection. It is very challenging to provide Efficiency parameter (Latency) support for different connection due to the feature of Master Driven TDD (Time Division Duplex). This paper addresses the issue to how to enhance Efficiency parameter (Latency) support in a Bluetooth piconet. I propose an scheduling algorithm which can provide Latency as Efficiency parameter for different connection based on priorities[1]. Considering the feature of Master Driven TDD, we define token counters to estimate traffic of real-time slaves. To increase bandwidth utilization, a backoff mechanism is then presented for best-effort slaves to decrease the frequency of polling idle slaves. Simulation results demonstrate that our scheme achieves better performance over the existing schemes.
