Abstract


At present, the wireless network technique is just more and more valued by people. Among them, a kind of new broadband wireless mesh networks (WMN) becomes the bit hot in the wireless network researches. Especially, wireless local area networks (WLAN) based on the IEEE 802.11 series protocols has been produced deep influence in our lives. With the development of wireless networks, Wireless Mesh Networks, compared with the traditional wireless infrastructure networks, with advantages such as gather and link in broadband wireless, valid routing and disaster discovering, Etc.The purpose of this paper is to realize long range supervision system research and realization based on WMN. For this purpose, Wireless key technique of the Mesh network, the network configuring and the factor for consider in the routing protocols are discussed. Therefore we analyze wireless power technique in the Physical layer and multiple accesses in the data link layer. At the same time, three structure of WMN are been discussed. We use AODV, which is a hop-by-hop on demand routing protocol, as IEEE 802.11 Wireless Mesh networks’routing protocol. Kernel allocation, modification of the code, routing protocol transplantation and test of AODV are also been discussed.In this paper, we select wireless audio and video supervise and control system as the application of IEEE 802.11 WMNs. In order to abstract the material object to module and upgrade the system, we adopt ideas about Object Oriented and Component Object to plan the audio and video Supervise and control system. There are three parts of the Supervise and control system:scene system、transmission network and center of control system. The data information can be collected, transmitted, storages and handled.In this paper, the surveillance end points use the Linux as the operating system, and the surveillance clients adopts Microsoft Windows system as the operating system.In a word, the ideas about Object Oriented and Component Object make our supervise and control system more efficiency.
