Dynamic selection of communication links in a mixed network
First Claim
1. A system comprising:
- a first station;
at least a second station;
wherein the first station and the second station are coupled to communicate via;
a first link to provide a direct wireless link between the first station and the second station;
a second link to provide an indirect wireless link between the first station and the second station; and
at least a third link to provide an indirect mixed link between the first station and the second station; and
wherein the first station includes a link selection component that is adapted to estimate the respective capacities of the first, second, and third links, and to dynamically select one of the links for transmission of a bitstream based on the estimation of the capacities of the first, second, and third links.

Abstract
Dynamic selection of communication links in a mixed network having wired and wireless links. An access point is coupled between at least two stations, with the access point coupled to a first station by a wired link and a wireless link. The access point is coupled to the second station by a wireless link. The first and second stations are coupled by a direct wireless link, and also at least two indirect links passing through the access point. A link selection component on the first station is operative to estimate the capacities of the various links, and to select one of the links for transmitting a bitstream. The link selection component can also dynamically re-select a link for continuing an on-going transmission of a given bitstream.
