Remote surveillance by network robot using WLAN and mobile IPv6 techniques

摘要

A network robot within the function of the remote surveillance using WLAN and mobile IPv6 techniques is proposed. The network robot can receive the command from the remote control center, patrol like a guard, and continually transmit images grabbed by the web cam back to the control center. In this service architecture, the Network Robot uses the WLAN to connect with the Internet. The control center shall communicate with the network robot within a fixed IP address. When the Network Robot crosses the area of WLAN, the problem without the fixed IP address shall be solved. In this paper, the mobile IPv6 technology is implemented on a robot to afford the smooth handoff on a fixed IPv6 address to shorten the time of the broken connection through different WLAN areas. Besides, the implemented mobile IPv6 function also solves the status of the triangular routing to achieve the optimization on the routing of the packet transmission. Finally, the successful experience results show the feasibility of our system.
