基于Linux的蓝牙系统核心协议栈的设计与实现

DESIGN AND IMPLEMENTATION OF THE BLUETOOTH KERNEL PROTOCOL BASED LINUX

本文设计与实现的基于Linux平台的Bluetooth核心协议栈主要由四个模块组成 :服务发现协议SDP模块 ,逻辑链路控制与适配协议L2CAP模块 ,串行线路模拟协议RFCOMM模块和主机控制接口HCI模块。在本核心协议栈的设计过程中 ,始终将提高整个协议栈的执行效率作为第一目标。为提高协议栈的效率 ,对协议栈进行了设计优化 ,采用了状态自动机、散列技术、缓冲机制、开放式平台。

This thesis describes a plan of designing and implementing Bluetooth protocol stack on Linux platform that is designed by myself.This plan has four pieces of modules:SDP,L2CAP,RFCOMM,HCI.During the design of the protocol stack,I think that the efficiency is most important.In order to raising driver efficiency,we used many advanced methods:finite-state automata,hash table,buffer pool,hardware simulation technology,open platform.
