With the development of communication technology and network technology , wireless sensor networks have become one of the hot areas of research information . Wireless sensor network communication between the \The papers in the project team for many years wireless sensor network research based on the design of a Wi-Fi - based image sensor network node , and build an image sensor network for tracking of moving objects . Firstly wireless sensor networks research background , introduced a variety of wireless communication technologies compare sensor nodes , analysis of current wireless sensor network research ideas and the main method used for target tracking applications . On this basis , combined with the convenience of Wi-Fi communication mechanism with the existing network interaction as well as the image sensor to identify the advantages of moving objects , designed image sensor network target tracking system based on Wi-Fi , and describes the overall architecture of the system nodes , the overall process of the hardware and software environment and system . Then, the design and development of wireless sensor networks , Wi-Fi communication mechanism to ensure that the wireless sensor node wireless network user data communication and information exchange ; realized after the image sensor node information acquisition , image processing , and the object coordinate transformation , and detailed analysis and presentation of the collaboration between the nodes to achieve the target tracking process . Eventually moving target coordinate information sent by way of Wi-Fi to the server to complete the target trajectory display . Subsequently, through building the actual testing environment , target tracking moving objects experiment results show that the system can be quickly and effectively show the trajectory of a moving object .
