Wireless networks are increasingly popular as the last-mile solution for a ubiquitous communication infrastructure. This trend in combination with the users? growing interest and falling cost in accessing vast amount of resources in Internet wirelessly has driven the developments of hybrid wireless network architecture such as Internet-based mobile ad hoc networks (IMANETs) and Internet-based vehicular ad hoc networks (IVANETs). However, it brings critical challenges in terms of limited storage space, frequent disconnections due to mobility, as well as unreliability of communication links. Caching a frequently accessed data in a local storage is shown to be an effective technique not only to relieve the network but also to improve data accessibility and availability in the presence of such challenges. The specific goal of this project is to develop algorithms and communication protocols that allow efficient and correct data caching in Internet-based wireless mobile networks. This project investigates cache management and invalidation strategies for IMANETs, and cache invalidation and consistency strategies for IVANETs. The project will make significant advances in understanding and designing an efficient data caching schemes for Internet-based wireless mobile networks. The success of this project will have a much broader impact on Internet-based wireless mobile network education and the corresponding industry, and provide versatile research opportunities to both undergraduate and graduate students. The algorithms and techniques developed in this research will be integrated with the education curricula

无线网络越来越流行，作为无处不在的通信基础架构的最后一英里解决方案。与用户结合使用的趋势？在无线上访问大量资源的兴趣和成本下降促进了混合无线网络体系结构的发展，例如基于Internet的移动临时网络（IMANET）和基于Internet的车辆临时网络（IVANETS）。但是，它在有限的存储空间，由于流动性以及通信链接的不可靠性方面带来了关键的挑战。在本地存储中，缓存经常访问的数据被证明是一种有效的技术，不仅可以减轻网络，而且还可以在存在此类挑战的情况下提高数据可访问性和可用性。该项目的具体目标是开发算法和通信协议，以允许基于Internet的无线移动网络中有效，正确的数据缓存。该项目研究了IMANET的缓存管理和无效策略，以及ivanets的缓存无效和一致性策略。该项目将在理解和设计基于Internet的无线移动网络的有效数据缓存方案方面取得重大进步。该项目的成功将对基于Internet的无线移动网络教育和相应的行业产生更大的影响，并为本科生和研究生提供多功能的研究机会。这项研究中开发的算法和技术将与教育课程集成
