中文简介: | 大多数真实网络通常随着时间演变:拓扑的变化可以在一些节点和/或边缘出现和/或消失时发生,并且即使拓扑是静态的,节点和边缘的类型或权重也可以改变。具有无线功能的移动设备(移动电话,笔记本电脑等)是演变网络的典型示例,其中节点或用户在环境中传播,并且用户之间的连接只有在他们靠近每个人时才会发生。每当用户移动时,谁接近网络将会发展,并且任何信息的传播等通信服务都会在移动性和底层网络的特性上发生。我们将在这里展示一些关注三个关键问题的结果,使用典型的演进网络描述和建模不断发展的网络,其中41个传感器已经分发给会议的参与者,该会议要求始终保持传感器。每个传感器都能够检测并记录其无线电范围内其他传感器的存在,从而提供有关参与者接近度的信息 |
课程简介: | Most real networks often evolve through time: changes of topology can occur if some nodes and/or edges appear and/or disappear, and even if the topology stays static, the types or weights of node and edges can also change. Mobile devices with wireless capabilities (mobile phones, laptops, etc.) are a typical example of evolving networks where nodes or users are spread around in the environment and connections between users can only occur if they are near each others. This who-is-near-who network is going to evolve every time users move and communication services such as the spread of any information will deeply rely on the mobility and on the characteristics of the underlying network. We will present here some results focusing on three key problems - measuring, describing and modeling evolving networks - using a typical evolving network where 41 sensors had been distributed to participants of a conference, which where asked to keep the sensor at all time. Each sensor was able to detect and record the presence of others sensors within their radio range which gives some information on the proximity of participants |
