power consumption

The base specifications of wireless sensor network (WSN) are low power consumption, self-organization and heterogeneous interconnection, and these newest morphology can't be described by traditional theories and models. A large number of potential applications make it hot for researches of theories and application. Wireless Sensor Network is a self-organizing plus size wedding dresses network, so that the information of physical environment will take the initiative to send information to the human world by wireless network. According to information available to judge, wireless sensor networks can help us feed back our intention into the objective world. This will be an entirely new means of communication between human beings and nature.Wireless sensor network is not isolated, interconnection with existing heterogeneous will only be meaningful, and this research is also relatively cheap wedding gown dresses small. The task of research is to solve interconnection issues between wireless sensor networks and heterogeneous network, and design essential networking equipment for wireless sensor networks (Gateway). Research goal is to design a gateway between wireless sensor network and custom made prom dresses Ethernet. Based on in-depth analysis of many gateway models, a better discount wedding gowns model of hardware and software architecture of the gateway is proposed, and hardware based on ARM-based embedded systems, software based on Windows CE embedded operating system. Under the guidance of this framework, gateway hardware platform and gateway software are designed. Two protocols can be understood in the gateway, and data can be exchanged two-way. In order to test the performance of hardware and best clothes blog software of gateway, a complete wireless sensor network is built to test the performance of the gateway and get some measures for improvement.
