摘　　要：随着无线网络技术的迅速发展,移动即时通信已经成为电信行业的主要应用之一.XMPP是一种以XML为基础的开放式主流即时通信协议.针对XMPP协议在移动设备上高功耗、高带宽问题,通过研究XMPP核心标准,结合最新的XMPP扩展协议,指出了引起这些问题的原因并给出相应的解决方案.在功耗方面,提出一种兼顾传输安全性和功耗的安全体系结构SAX;在带宽方面,提出了实体能力算法、节过滤和拦截算法,用于减少XMPP实体间通信所需的XML流.最后在Android系统上进行功耗和带宽测试,测试结果表明,解决方案有效地降低了功耗并节约了带宽.With the rapid advancement of wireless network technologies, Mobile Instant Messaging has become a major application in the telecommunications industry. XMPP is an open standard communications protocol for Instant Messaging based on XML. Aim at the problem with high energy consumption and high-bandwidth of XMPP on mobile devices, through studying XMPP core standard, combined with the latest XMPP Extension Protocol, this paper points out the causes of the problems and give the corresponding solu- tions. In terms of power, we propose an architecture presenting a balance between security and energy, named SAX; while in terms of bandwidth, we propose an entity capabilities algorithm, stanza interception and filtering algorithm, both of them can reduce the number of XML stream of communication between XMPP entities. Finally, we have a test on Android System, the results show that the solution effectively reduces the power consumption and saves bandwidth.
