Abstract

During recent years, with the rapid development of wireless sensor technologies, Wireless Sensor Network (WSN) systems are widely used in various applications, such as environmental monitoring, smart home and so on. A WSN system is a self-configuring network of sensor nodes connected by wireless links. The union of sensor nodes forms an arbitrary topology. Routing in a WSN system is a critical task. Therefore, the routing protocol has much effect on the throughout performance and energy consumption of the whole network. Most available routing protocols employ distributed structure that is complex and has high energy consumption. Compared with these distributed protocols, a novel centralized routing protocol with a central node is proposed. And all kinds of routing management of the whole WSN systems are centralized in the central node. The centralized management strategy reduces routing overhead and energy consumption of the whole network. Finally, a WSN system with Raspberry Pi and OpenWrt is designed to evaluate the new method. Experiment results show that it is very efficient.

无线传感器网络集中式路由协议的设计与实现

近年来，随着无线传感器技术的飞速发展，无线传感器网络(WSN)系统被广泛应用于环境监测、智能家居等各个领域。WSN系统是由无线链路连接的传感器节点组成的自配置网络。传感器节点的联合形成任意拓扑。路由是无线传感器网络系统中的一项关键任务。因此，路由协议对整个网络的性能和能耗有很大的影响。现有的路由协议大多采用分布式结构，结构复杂，能耗高。与这些分布式路由协议相比，提出了一种具有中心节点的集中式路由协议。整个无线传感器网络系统的各种路由管理都集中在中心节点上。集中管理策略降低了整个网络的路由开销和能耗。最后，设计了一个基于树莓派和OpenWrt的WSN系统来评估新方法。实验结果表明，该方法是非常有效的。
