移动自组网络(MANETS)是一种具有弱连接性、低带宽、高查询延迟的网络。协缓存技术被广泛用来实现MANETS中数据的高效分发与共享,然而协缓存技术极易引发数据不一致性。为了有效解决现有MANETS中存在的数据不一致性问题,提出一种使用移... 移动自组网络(MANETS)是一种具有弱连接性、低带宽、高查询延迟的网络。协缓存技术被广泛用来实现MANETS中数据的高效分发与共享,然而协缓存技术极易引发数据不一致性。为了有效解决现有MANETS中存在的数据不一致性问题,提出一种使用移动窗口来预测选定缓存节点的协缓存算法(Mobile Window Caching Consistency,MWCC)。实验表明,该算法能有效解决MANETS中因协缓存技术带动来的数据不一致性问题,并在很大程度上减少了通信拥塞与查询延迟。 展开更多

This paper provides a comprehensive survey of the impact of the emerging communication technique, non-orthogonal multiple access (NOMA), on future wireless networks. Particularly, how the NOMA principle affects the design of the generation multiple access techniques is introduced first. Then the applications of NOMA to other advanced communication techniques, such as wireless caching, multiple-input multiple-output techniques, millimeter-wave communications, and cooperative relaying, are discussed. The impact of NOMA on communication systems beyond cellular networks is also illustrated, through the examples of digital TV, satellite communications, vehicular networks, and visible light communications. Finally, the study is concluded with a discussion of important research challenges and promising future directions in NOMA. 展开更多
