Wireless P2P networks, such as ad hoc networks, mesh networks, and sensor networks, have received considerable attention due to their potential applications in many civilian and military environments. The design of such networks that consider performance and power optimization has become a recent research focus. As nodes in wireless P2P networks may perform similar tasks using common data sets, collaborative data access, which allows sharing and coordination of cached or replicated data among multiple nodes, can be used to reduce the bandwidth and power consumption. The specific goal of this project is to provide a collaborative data access framework for wireless P2P networks. The project addresses four intertwined issues: (i) various cooperative caching schemes will be designed, implemented, and evaluated; (ii) suitable cache replacement and cache admission control algorithms are proposed and evaluated to balance the tradeoffs between access latency and data accessibility; (iii) novel data replication and data discovery techniques are investigated to further reduce the access latency and increase the data accessibility; (iv) possible security violations to maintain data consistency will be identified, and solutions to defend against such attacks will be proposed. The project will make significant theoretical advances in understanding and designing wireless P2P networks using the collaborative data access concept, and will develop a comprehensive software support for collaborative data access in wireless P2P networks. The success of this project is likely to have a broader impact on making wireless P2P networks more affordable and amenable to commercial, civilian, and military applications. The results of the project will be disseminated widely through high-quality publications and discussions. The proposed research will also be integrated with the education curricula at Penn State.

无线P2P网络，如ad hoc网络、mesh网络和传感器网络，由于其在许多民用和军事环境中的潜在应用而受到相当大的关注。考虑性能和功耗优化的网络设计已成为近年来的研究热点。由于无线P2P网络中的节点可以使用公共数据集来执行类似的任务，因此允许在多个节点之间共享和协调缓存或复制的数据的协作数据访问可以用于减少带宽和功耗。该项目的具体目标是为无线P2P网络提供一个协同数据访问框架。该项目主要解决四个相互交织的问题：（i）设计、实现和评估各种合作缓存方案;（ii）提出和评估合适的缓存替换和缓存接纳控制算法，以平衡访问延迟和数据可访问性之间的权衡;（iii）研究新的数据复制和数据发现技术，以进一步减少访问延迟并提高数据可访问性;（iv）找出可能违反保安规定以维持资料一致性的情况，并提出防御该等攻击的解决方案。该项目将在使用协作数据访问概念理解和设计无线P2P网络方面取得重大理论进展，并将为无线P2P网络中的协作数据访问开发全面的软件支持。该项目的成功可能会对无线P2P网络产生更广泛的影响，使其更经济实惠，更适合商业，民用和军事应用。该项目的成果将通过高质量的出版物和讨论广泛传播。拟议的研究也将与宾夕法尼亚州立大学的教育课程相结合。
