摘　　要：用户节点通过多跳转发实现通信将会耗费大量的通信成本,研究设计了应用于办公自动化过程中的视频协同信息共享技术,该技术构造移动自组网(Mobile Adhoc Network,MANET)物理拓扑结构感知参数,同时提出时空感知的个性推荐算法。无拓扑感知和拓扑感知信息共享方法的平均邻居个数分别为5.6个和10.5个,提升率约为88.0%。对比于其他个性推荐算法,引入时间权重的推荐算法具有更低的节点命中个数和更高的平均跳数。该技术在实现时空感知的信息共享技术过程中将用户节点间的通信代价和用户间的兴趣相似度考虑在内,进而组建一个节点间数据通讯的高质量邻接网。通过这种方法能有效降低覆盖网络内部的通信量,维持良好的网络拓化结构,提高MANET网络的可扩展性,为用户提供更好的服务。The implementation of communication by user nodes through multi hop forwarding will consume a large amount of communication costs.A video collaborative information sharing technology applied in office automation processes has been studied and designed.This technology constructs physical topology perception parameters for Mobile Ad Hoc Network(MANET),and proposes a spatiotemporal perception personalized recommendation algorithm.The average number of neighbors for topology aware and topology aware information sharing methods is 5.6 and 10.5,respectively,with an improvement rate of approximately 88.0%.Compared to other personalized recommendation algorithms,recommendation algorithms that introduce time weights have lower node hits and higher average hops.This technology takes into account the communication cost between user nodes and the similarity of interests between users in the process of implementing spatiotemporal aware information sharing technology,and then forms a high-quality adjacency network for data communication between nodes.This method can effectively reduce the traffic within the overlay network,maintain a good network topology structure,improve the scalability of MANET network,and provide users with better services.
