  • Publication number: 20080205429
    Abstract: In a method for assigning transmission channels to links based on link-directionality in carrier sense wireless networks. The transmissions between two nodes of a link can be split into two channels based on their link-directionalities, one channel for transmitting traffic in one direction while the other channel for sending traffic in another direction. Simultaneous transmissions of a nearby node can be assigned based on link-directionality with a different transmission channel if it is within the carrier sensing region of the link or the same transmission channel if it is far enough from the link, which does not affect the reception of the link.

  • Publication number: 20080172172
    Abstract: In a process for determining a route from a predetermined starting point to a predetermined destination, firstly, weights are assigned to route segments interconnected at route nodes. At least a first weight relating to a first route segment is varied by querying at least a data source based on at least a second weight relating to a second route segment. The second route segment is prior to the first route segment in a consideration of the route from the starting point to the destination. Subsequently, the route is determined by using a route finding algorithm, the algorithm taking the weights into account.
