基于卫星及无线Mesh网的组网技术研究与应用
|
摘要
针对地震现场应急通信网络时间突发性、地点不确定性、业务紧急性和信息多样性等特点,提出一种基于卫星及无线Mesh网的组网方法。首先,对无线Mesh网概念及其特点、组网模式进行阐述;其次,对无线Mesh网组网的关键技术进行详细探讨;结合卫星通信技术特点,对基于卫星及无线Mesh网的组网方法进行详细设计并实现。该组网方法是一种搭建现场应急通信网络平台行之有效的方法。
Aiming at the characteristics of time suddenness,location uncertainty,business urgency and information diversity of the emergency communication network at earthquake site,a networking method based on satellite and wireless Mesh network is put forward. The concept,characteristics and networking mode of wireless Mesh network are described. The key technologies of wireless Mesh network are discussed in detail. The characteristics of satellite communication technology are combined to design and implement the networking method based on satellite and wireless Mesh network in detail. The networking method is an effective one of the site comnunication network platform.
