通过基础网络互联多个传感器网络,为用户提供大规模、大范围、多样化的信息服务成为未来无线传感器网络的应用模式之一。据此,提出了一种基于P2P(Peer-to—Peer)技术的无线传感器网络应用架构。采用P2P技术,解决了大数据量的通信瓶颈,传感器网络亦可自由加入、变更或退出,方便部署,网络可扩展性好.同时屏蔽底层网络差异及多种接入方式.为用户提供多个访问入口。
With the recent development of the wireless sensor networks (WSN), it can be envisioned that the future wireless sensor networks will be Connected by the infrastructure network such as the Internet and accessible to a wide range of applications. In this paper, we propose a P2P-based application framework (P2PWSN) for wireless sensor networks. The P2P technology alleviates the data communication bottleneck and allows easy deployment and free join-in and retreat-from of WSNs, improving the WSN scalability. It also hides the heterogeneity of the underlying networks and provides multiple access to the users.
