无线传感器网络M2M网关的设计与实现

本文主要论述了无线传感器网络与M2M平台对接的关键性技术——M2M网关的设计与实现。无线传感器网络（WSN）具有独立自组网和超低功耗等优点，但是由于其短距离通信的特征，使其应用范围有所限制。将WSN与M2M平台进行对接，是无线传感器网络发展的必然趋势；而M2M网关则是实现对接的关键性技术。无线传感器网络M2M网关，采用嵌入式ARM9处理器S3C2440为核心；以CC2530作为汇聚节点采集WSN数据；利用GPRS模块EM310为网络数据的出口，对接M2M平台服务器。该M2M网关可将WSN与M2M平台相连接，具有很好的通用性，可广泛使用在众多物联网的实际应用中。

Design and implementation of M2M gateway of wireless sensor network

This paper mainly discusses the key technology of connecting wireless sensor network with M2M platform-design and implementation of M2M gateway. Wireless sensor network (WSN) has many advantages such as independent ad hoc network and low power consumption. However, because of its feature of short distance communication, its application scope is limited. It is an inevitable trend in the development of wireless sensor networks that connecting WSN to M2M platform, while M2M gateway is the key technology to achieve the docking. Wireless sensor network M2M gateway use the embedded ARM9 processor S3C2440 as the core; CC2530 as the sink node to collecting data of WSN; GPRS module EM310 as the export of network data to docking the M2M platform server. The M2M gateway, which can connect WSN with M2M platform, can be widely used in a lot of practical application of Internet of Things with strong universality.
