Research on Wireless Sensor Network and Carrying Network Integration Based on Gateway

In this paper, we analyze the protocol architecture of Wireless Sensor Networks (WSNs) and carrying networks, and propose a connection scheme based on gateway, which is suitable to the integration of these two networks. According to the characteristics of these gateways, we put forward the concept of end-to-end connection, give the address mapping scheme to the gateway and design a simple gateway node. To realize higher connection reliability, we advance a method of backup gateway and multi-gateways selections. This work can greatly facilitate the research for connecting WSN with the carrying network, IoT (Internet of Things), which also makes contribution to the influence of this connection.
