23175 传统缓存方案通常为网络内的单一全局协作策略，然而不同网络区域的缓存目标不同，导致传统方案的性能优化程度有限，可扩展性不强。 Most of traditional caching coordination research use uniform caching policies within the same cache network, but the aim of different network part is quite various, thus the existed schemes are hard to achieve a comprehensive performance optimization or hard to scale.
23176 同时协同缓存放置和请求路由，相较于纯缓存方案有效性更高。 Additionally, most work fail to adapt to the on-path coupling effect content caching and request routing.
23177 该文提出并评估了一种新型面向分域的协作混合缓存放置和路由请求机制，该机制将缓存网络区分核心网络和边缘网络，在核心网络中采用非沿路的HASH 协作机制，边缘网络采用沿路的回退协作机制，创建二元组标签保存缓存放置的信息并作用于后续的请求转发。 This paper proposes and evaluates novel domain-orientated coordinated hybrid content caching and request search in ICN, which fully exploit content- space partitioning and divide the cache network into a core area and several edge areas. The off-path HASH-based coordination scheme is applied to core area and on-path reversion scheme is deployed in edge areas. The binary tuple is created to record the information of content placement and guides the request routing.
23178 通过仿真对比表明，该文提出的协作混合缓存机制相较于传统策略可以更好地平衡网络资源利用和用户体验，并在大型 ISPs 中拓展性更好。 Through simulation and comparison, it is found that the proposed policies yield better tradeoff between network-centric and user-centric performance than traditional schemes, and are scalable to be used in large ISPs.
23179 为了提高认知无线电网络的频谱利用率，该文提出对认知无线网络频谱感知估计时间进行优化。 In order to improve the spectrum efficiency in the cognitive radio networks, the optimization algorithm of the spectrum sensing estimation time is presented.
23180 如果频谱感知时间较长，一方面对信道参数的估计更准确，会减小对授权用户的干扰并提高认知用户的吞吐量； The longer sensing time will bring two aspects of the consequences. On the one hand, the channel parameters are estimated more accurate so as to reduce the interference to the authorized users and to improve the throughput of the cognitive users.
23181 另一方面，数据传输时间相应缩短，使系统吞吐量减小，这时存在一个最优的感知时间使得系统吞吐量最大。 On the other hand, it shortens the transmission time so as to decease the system throughput. In this time, it exists an optimal sensing time to maximize the throughput.
23182 该文认为子频段的信道状态信息服从指数分布，故提出随机规划的方法，对认知无线网络频谱感知估计时间进行优化运算。 It is considered that the channel state information of sub-bands is exponentially distributed, so a stochastic programming method is proposed to optimize the sensing time of the cognitive radio networks.
23183 计算机仿真结果表明，该算法是切实有效的，具有一定的工程应用价值。 The computer simulation results show that the algorithm is effective and has a certain engineering application value.
23184 为了增加水下高速目标的识别特征维度，优化识别效果，该文设计了一种基于目标辐射噪声高速特征量(High Speed Characteristic Quantity, HSCQ)的分类方法。 In order to improve the result of underwater high speed vehicle classification, a classification method that is based on High Speed Characteristic Quantity (HSCQ) of vehicle radiated noise is designed.
