中文摘要：

日益普及的无线网络和移动设备为普适的Internet接入提供了良好的硬件基础，缓存技术是普适Internet场景中人们进行信息共享和分发的关键技术之一。综述了两类无线网络环境，即基于基础设施无线网络环境和移动自组网中的缓存策略，具体包括缓存放置策略、缓存替换策略、缓存一致性维护算法。进而分析、讨论了上述策略的优缺点，并指出了缓存策略的发展趋势。

英文摘要：

The growing wireless networks and mobile devices provided a good basis of the hardware for universal access to the Internet. Caching technology is one of the key technologies which enables people to share and distribute information in pervasive Internet environments. This paper summarizes two types of wireless network environment, that is, caching strategies for the infrastructure-based wireless network and mobile ad hoc network. The advantages and disadvantages of specific strategies, including cache placement strategy, cache replacement strategy and cache consistency maintenance algorithm are analyzed and discussed. This paper also points out the trends of caching strategies.
