摘要： 基于IEEE802.11b和Bluetooth两大协议标准的无线网络解决了有线通信不便移动、缺乏灵活性和使用不便问题，因此越来越受青睐.该文分析与研究了工作于嵌入式移动环境的应用层协议——蓝牙服务搜索协议（SDP）体系架构、服务搜索机制及其实现，通过和IEEE802.11b协议的比较，针对SDP的不足提出了改进思路，从而加强了其安全性和传输速度.

Abstract: Wireless Network which is based on two protocols: IEEE802.11b and Bluetooth solves the problems of wire communication moving inconvenience, lacking in flexibility and use inconvenience. This paper analyzes and researches system architecture, service search engine and realization of SDP which is working in the embedded mobile environment, and suggests some improvement ideas on its shortage which is concluded from the comparison to IEEE802.11b to enhance its security and transfer speed.
