Progress of video coding technologies and speed up of wireless LAN are enabling short range wireless transmission from mobile camera to base station.
However, this wireless transmission was often disconnected by
deteriorating signals or blocking.
To avoid this disconnection, multiple wireless access points work with wireless LAN controller to hand over connections or mobile ad hoc network technology to make detour path are used.
Since these technologies require wireless devices to measure signal strength and to make use of them for route controller, they can't be applied to generic wireless LAN devices.
We therefore made a redundant path switcher which make use of commodity wireless devices.
It monitors path condition by periodical probing packet.
In this paper, its switching mechanism and its probing conditions for preventing transmission errors are discussed. |
