We design a kind of wireless sensor networks gateway nodes based on IP2022 and nRF905; also, the industry application of nodes designed is studied, the thought of the industry application is given out.
Wireless sensor network consists of large number of sensor nodes randomly distributed in some regions. Each node has a limited energy supply and generates information when some events that need to be communicated to a sink node occur. It has been proved that the nodes closer to the sink node will use up their energy more quickly, as a result, the network lifetime will be affected, some bad consequences...
