Introduction

Introduction

  • Bluetooth have the potential to ensure the best services, system resources and quality.

  • The BLUEPAC (BLUEtooth Public ACcess) can enable mobile Bluetooth devices to access local area networks.


Introduction1

Introduction

  • BT can access IP network services using the

    • IETF Point-to-Point Protocol (PPP) and

    • the Bluetooth Network Encapsulation Protocol (BNEP).


Introduction2

Introduction

  • To provide high QoS in a Bluetooth-IP mobile environment, a pre-requisite for our discussion is seamless data transmission.

  • A cascading system:

    • fair resource allocation scheme,

    • seamless handoff strategy, and

    • transparent bridging system

Qos centric cascading mechanism

QoS-centric cascading mechanism

  • QoS is critical in transmitting of different network segments.

  • a QoS-centric cascading mechanism


Qos centric cascading mechanism1

QoS-centric cascading mechanism

  • Intra-piconet resource allocation

  • Inter-piconet handoff

  • Bluetooth-IP access system


Qos centric cascading mechanism2

QoS-centric cascading mechanism

  • Intra-piconet resource allocation

    • Two service types:

      • Synchronous Connection Oriented (SCO) and

      • Asynchronous Connectionless Link (ACL)

        • Flush Timeout
