泛在网络在新时期下强调面向应用的特征,因此有必要对泛在网络的研究内容和技术体系进行梳理.本文基于对泛在计算与泛在网络起源、概念与特征的理解,辨析了泛在网络与传感网、物联网之间的关系,提出了泛在网络的分层架构与概念模型,分析了泛在网络挑战和关键技术,并提出研究及发展建议.
It's necessary to have deep understanding on the ubiquitous networks, including the origin, concepts and characteristics of ubiquitous computings. The relations between ubiquitous networks, sensor networks and internet of things are analyzed. A layered architecture and information plane model of ubiquitous networks is presented. Suggestions on key technologies and challenges the ubiquitous networks has to meet are proposed.
