sensor nodes

Wireless sensor networks (WSN) is composed of large number of sensor nodes which are deployed in monitoring region, it is forming a multi-hop and self-organized network system through wireless communication, the information of chi pink dazzle monitored area is cooperatively sensed, collected and processed. WSN can be applied in Lacoste Polo Shirts medical treatment, environment monitoring, and minitary area.Zigbee technology is a chi flat iron unified technical standard for short-range wireless communication technologies. Zigbee protocol stack is composed of Physical layer, MAC layer, network layer, security layer and application layer. chi flat iron protocol defined the Physical layer and MAC layer, Zigbee Alliance developed the network chi hair straighteners layer and security layer. The development of application layer should be based on the user's own needs. Zigbee technology is a standard wireless network protocol designed for low-rate hair straighteners sensor and control network; meanwhile, it is the most chi dazzle suitable standard protocols for wireless sensor networks.Currently, wireless sensor network research is still in its infancy.
