简介:活动性支持上的同样不同的要求将被多样化的通讯情形在第五代(5G)介绍,在需求活动性管理上被提出简化发信号的过程,还原剂终端电源消费,等等改进网络效率。为了在5G在需求活动性管理上启用,联网,驾驶的活动性(MDNS)当为不同活动服务设定网络时,网络切被建议,它考虑单个活动性支持要求。在MDNS框架以内,要求的活动性支持的实际层次被一个活动性描述系统决定,并且与相应活动性管理计划联网片模板被一个网络片描述函数定义。由用具体例子说明,网络切,每个活动终端能与最适当的活动性管理计划被指导到网络片。基于这,一个原型被实现验证MDNS框架的可行性,即与不同活动性管理创造多重网络片策划。另外,平均处理一个活动性事件花费的性能评估为建议MDNS框架被进行,长期的进化(LTE)系统,和操作好处包括效率和可伸缩性被分析。
简介:网络活动性(NEMO)是为一个整个网络的活动性管理建议的一个协议。它为无缝的因特网提供连接到活动终端用户。然而,NEMO协议广泛地没在因特网被使用,因为它没关于认证和授权考虑安全问题。建议框架设计了特别为NEMO网络环境使用的一个存取控制计划。它基于认证,授权,和财务(AAA)系统。同时为所有活动节点证实能使用活动路由器,并且使用活动网络节点(MNN)控制MNN的安全存取的表同步机制。由使用外国AAA服务者缓存机制,这个计划能减少认证时间推迟并且改善网络的效率。优点被比较经由OPNET模拟与另外的最近的相关研究证明。

简介:都市化的过程被人的常规运动形成。它在一个城市里产出不同功能的地区,例如居住地区和商业地区。因而,在那里存在在人的活动性模式和城市之间的一个靠近的连接是地区。然而,收集能精确捕获在个人的运动和地区性的功能之间的内在的关系的大规模社会宽的数据不是容易的。因此,我们为理解人的活动性的基本模式的知识仍然是有限的。以便在一个城市里发现不同区域的功能,我们建议一种亲密关系在这份报纸基于方法。亲密关系是为在一个复杂网络测量二个连接节点的关联的一个最近介绍的度量标准。建议模型由经由相对的熵测量用户的到达/离开分发组织不同功能的地区。除了这,我们也由拿核密度评价(KDE)识别每个功能的地区的紧张方法。最后,一些实验被进行与大规模真实数据集评估我们的方法,它从一个月的一个时期由300万个蜂窝电话用户的记录组成。我们在活动性模式和地区性的函数之间的相互作用上的调查结果能高效地捕获城市动力学并且为城市的规划者提供珍贵引用。
